WDR-240-24 Overview
The DAPPRA WDR-240-24 (SKU: OF62) is a 240W single-output industrial DIN rail power supply in the WDR Series. It provides a stable 24V DC output at 10A rated current from an ultra-wide 180–550 VAC single-phase or two-phase input, or 254–780 VDC input, with 91% typical efficiency at 400VAC and built-in active PFC (PF ≥0.84).
Positioned between the 120W WDR-120-24 and the 480W WDR-480-24, the WDR-240-24 doubles the output current of the 120W model while retaining the same ultra-wide input capability. It accepts two phases of a 380V/400V/480V three-phase network without a neutral, features a 63 mm metal housing, fanless natural convection cooling, a DC OK relay contact rated for higher loads (60VDC/0.3A), and complete protection functions. Overload protection includes a 3-second shutdown with auto-recovery after approximately 1 minute, and over-voltage protection (29–33V) also uses delayed auto-recovery. The unit operates from −30°C to +70°C with derating above +50°C.

WDR-240-24 Installation
The WDR-240-24 supports TS35 DIN rail mounting with specific ventilation clearance and orientation requirements for reliable operation.
Vertical Orientation Only
The appropriate mounting orientation is vertical — input terminals at the bottom and output terminals at the top. Upside-down, horizontal or table-top mounting is not allowed, as sufficient cooling will not be possible.
Ventilation Clearance
Always allow good ventilation clearances around the unit: 5 mm left and right, 40 mm above and 20 mm below, to prevent overheating. When the adjacent device is a heat source, keep 15 mm clearance.
TS35 DIN Rail Mounting
Admissible DIN rail: TS35/7.5 or TS35/15. Tilt the unit slightly rearwards, fit over the top hat rail, slide it downward until it hits the stop, press against the bottom for locking, then shake slightly to check the locking action.
FG Must Be Connected to PE
The FG (Frame Ground) terminal must be connected to PE (Protective Earth) for safety and to ensure proper EMC performance.
Operating Temperature Limits
The WDR-240-24 operates from −30°C to +70°C, with derating required above +50°C. Do not install near fire sources or in high ambient temperature locations.
Pollution Degree 2 Environment
Install the unit only in a pollution degree 2 environment — typically dry, well-ventilated locations such as control cabinets. Do not install in places with high moisture or near water.
WDR-240-24 Wiring & Terminal
The WDR-240-24 uses two terminal blocks: TB1 for input and TB2 for output. TB2 pin order differs from the WDR-480 — verify the terminal label before wiring.
Terminal Pin Assignment
| Pin No. | Assignment |
|---|---|
| 1 | FG (Frame Ground) |
| 2 | AC/L2 |
| 3 | AC/L1 |
Single-phase: L1 live, L2 neutral. Two-phase: L1 and L2 to two phases, no neutral.
| Pin No. | Assignment |
|---|---|
| 1, 2 | DC OK relay contact |
| 3, 4 | DC OUTPUT +V |
| 5, 6 | DC OUTPUT −V |
Note: The WDR-240 TB2 order is relay first, then +V, then −V. The WDR-480 uses +V first, then −V, then relay. Verify terminal labels before wiring.
The FG pin must be connected to PE (Protective Earth). Both +V pins (3, 4) and both −V pins (5, 6) should be connected to their respective output wires to prevent excessive current stress on a single contact. The DC OK relay contact is a dry contact — do not use it as a power output.

WDR-240-24 Installation
The WDR-240-24 supports TS35 DIN rail mounting with specific ventilation clearance and orientation requirements for reliable operation.
Vertical Orientation Only
The appropriate mounting orientation is vertical — input terminals at the bottom and output terminals at the top. Upside-down, horizontal or table-top mounting is not allowed, as sufficient cooling will not be possible.
Ventilation Clearance
Always allow good ventilation clearances around the unit: 5 mm left and right, 40 mm above and 20 mm below, to prevent overheating. When the adjacent device is a heat source, keep 15 mm clearance.
TS35 DIN Rail Mounting
Admissible DIN rail: TS35/7.5 or TS35/15. Tilt the unit slightly rearwards, fit over the top hat rail, slide it downward until it hits the stop, press against the bottom for locking, then shake slightly to check the locking action.
FG Must Be Connected to PE
The FG (Frame Ground) terminal must be connected to PE (Protective Earth) for safety and to ensure proper EMC performance.
Operating Temperature Limits
The WDR-240-24 operates from −30°C to +70°C, with derating required above +50°C. Do not install near fire sources or in high ambient temperature locations.
Pollution Degree 2 Environment
Install the unit only in a pollution degree 2 environment — typically dry, well-ventilated locations such as control cabinets. Do not install in places with high moisture or near water.
WDR-240-24 Wiring & Terminal
The WDR-240-24 uses two terminal blocks: TB1 for input and TB2 for output. TB2 pin order differs from the WDR-480 — verify the terminal label before wiring.

WDR-240-24 Safety & Cautions
Read and follow all safety instructions before installing, wiring, maintaining or modifying the WDR-240-24 power supply.
- Risk of electrical shock and energy hazard. All failure should be examined by a qualified technician. Do not remove the case of the power supply yourself.
- Connecting both the primary and the secondary sides together is not allowed — risk of electric arcs and electric shock (danger to life).
- Risk of burn hazard. Do not touch the unit in operation and shortly after disconnection.
- Risk of fire and short circuit. The openings should be protected from foreign objects or dripping liquids.
- The FG (Frame Ground) must be connected to PE (Protective Earth).
- Output current and output wattage must not exceed the rated 10A / 240W.
- Before commencing any installation, maintenance or modification work, disconnect the system from supply voltage. Make sure that inadvertent connection in circuit will be impossible.
- Do not use the DC OK relay contact as a power output. Observe its 60VDC/0.3A, 30VDC/1A or 30VAC/0.5A rating.
- The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
Note: Pollution Degree 2 applies where there is only non-conductive pollution that might temporarily become conductive due to occasional condensation. Generally refers to dry, well-ventilated locations, such as control cabinets.

WDR-240-24 FAQ
What is the DAPPRA WDR-240-24?
The DAPPRA WDR-240-24 (SKU: OF62) is a 240W single-output industrial DIN rail power supply providing 24V DC at 10A. It accepts an ultra-wide 180–550VAC single-phase or two-phase input, includes built-in active PFC, a DC OK relay contact, 3KVAC I/O isolation, and 91% typical efficiency at 400VAC.
What is the input voltage range of the WDR-240-24?
The WDR-240-24 supports an ultra-wide AC input range of 180–550VAC (single-phase or two-phase) and 254–780VDC. It is suitable for 220V, 380V, 400V and 480V mains networks, as well as two-phase operation of a three-phase system without a neutral.
Does the WDR-240-24 have built-in active PFC?
Yes. The WDR-240-24 includes built-in active power factor correction (PFC) with PF ≥0.84 at 400VAC and 230VAC under full load, compliant with BS EN/EN61000-3-2 harmonic current regulations. This is a key difference from the WDR-120-24, which does not have PFC.
What is the efficiency of the WDR-240-24?
The WDR-240-24 achieves 91% typical efficiency at 400VAC input and full load. Actual efficiency varies with input voltage and load conditions.
What is the output voltage adjustment range of the WDR-240-24?
The WDR-240-24 has a 24–28V output adjustment range via the front-panel +V ADJ potentiometer. This is narrower than the 24–29V range on the WDR-120-24, reflecting the different design of the 240W platform.
What is the over-voltage protection threshold of the WDR-240-24?
Over-voltage protection triggers at 29–33V for the 24V model. The output shuts down and recovers automatically after approximately 1 minute if the fault condition is removed. This delayed auto-recovery differs from the WDR-120-24, which recovers immediately.
What is the overload protection behavior of the WDR-240-24?
The WDR-240-24 uses 105–130% rated output power constant-current limiting. Unlike the WDR-120-24, the WDR-240-24 shuts down after approximately 3 seconds of overload, then recovers automatically after about 1 minute if the fault is removed.
What is the isolation voltage of the WDR-240-24?
The WDR-240-24 provides 3KVAC isolation between input and output (I/P-FG: 1.5KVAC, O/P-FG: 0.5KVAC). This is suitable for most industrial control and automation applications.
What is the terminal pin assignment of the WDR-240-24?
TB1 (Input): Pin 1 = FG, Pin 2 = AC/L2, Pin 3 = AC/L1. TB2 (Output, 6 pins): Pins 1,2 = DC OK relay contact; Pins 3,4 = DC OUTPUT +V; Pins 5,6 = DC OUTPUT −V. This order (relay first, then +V, then −V) differs from the WDR-480 — verify terminal labels before wiring.
Does the WDR-240-24 have a DC OK relay contact?
Yes. The WDR-240-24 includes a built-in DC OK relay contact on TB2 pins 1 and 2, rated 60VDC/0.3A, 30VDC/1A or 30VAC/0.5A. Contact Close = PSU turns on / DC OK; Contact Open = PSU turns off / DC Fail.
What is the operating temperature range of the WDR-240-24?
The WDR-240-24 operates from −30°C to +70°C with free air convection cooling. Derating is required above +50°C ambient.
What are the dimensions and weight of the WDR-240-24?
The WDR-240-24 measures 63 × 125.2 × 113.5 mm (W × H × D) and weighs approximately 1.06 kg. The 63 mm metal housing provides additional heat dissipation for the higher 240W output.
Can the WDR-240-24 power a 24V load at 10A continuously?
Yes, 10A at 24V equals the 240W rated output. Continuous full-load operation is specified within the −30°C to +70°C range, but derating is required above +50°C. In a typical control cabinet at 40–50°C, full 10A is achievable with adequate ventilation clearance.
What certifications does the WDR-240-24 have?
The WDR-240-24 is certified to UL508, TUV/EN62368-1 and AS/NZS62368.1, and complies with BS EN/EN55032 Class B, BS EN/EN61000-6-2 industrial immunity, and GL standards. Confirm certificate coverage for your destination market.
What is the MTBF of the WDR-240-24?
The WDR-240-24 has an MTBF exceeding 1.06 million hours (Telcordia SR-332) / 141.1K hours (MIL-HDBK-217F), reflecting the long-life design and active PFC topology of the 240W platform.
