Overview
HDR-30-24 Overview
The DAPPRA HDR-30-24 (SKU: SD93) is a 36W single-output ultra-slim DIN rail power supply in the HDR Series. It provides a stable 24V DC output at 1.5A from a universal 85–264 VAC input, with 89% typical efficiency and a ±10% output adjustment range of 21.6–29V.
At 35 mm (2SU) wide, the HDR-30-24 sits between the 17.5 mm HDR-15 and the 52.5 mm HDR-60. Class II double insulation eliminates the need for a protective earth connection, and LPS certification makes it suitable for limited-energy circuits. Protection includes short circuit, overload (105–160% constant current limiting, auto-recovery) and over-voltage (30–36V, shut-off with zener clamping). Ripple is 150mVp-p and no-load consumption is below 0.3W. The unit is well-suited to 24V sensor clusters and small relay banks whose combined draw stays within 1.5A.

HDR-30-24 FAQ
What is the DAPPRA HDR-30-24?
The DAPPRA HDR-30-24 (SKU: SD93) is a 36W single-output ultra-slim DIN rail power supply providing 24V DC at 1.5A. It features a 35 mm (2SU) plastic step-shape housing, Class II double insulation (no grounding required), LPS certification, and 89% typical efficiency.
What is the input voltage range of the HDR-30-24?
The HDR-30-24 supports a universal AC input range of 85–264VAC (277VAC operational) or 120–370VDC (390VDC operational).
What is the output voltage adjustment range of the HDR-30-24?
The HDR-30-24 has a 21.6–29V output adjustment range via the front-panel +V ADJ potentiometer (±10% of 24V). This window is sufficient for voltage-drop compensation without exceeding the tolerance of most 24V industrial devices.
What is the over-voltage protection threshold of the HDR-30-24?
The HDR-30-24 triggers over-voltage protection at 30–36V (125–150% of 24V). The protection type is shut-off output voltage with zener clamping, and the unit requires re-powering to recover.
What is the overload protection behavior of the HDR-30-24?
The HDR-30-24 uses 105–160% rated output power protection with constant current limiting. The unit recovers automatically after the fault condition is removed.
What is the ripple and noise of the HDR-30-24?
The maximum ripple and noise is 150mVp-p, measured at 20MHz bandwidth with a 0.1μF and 47μF parallel capacitor.
What are the dimensions and weight of the HDR-30-24?
The HDR-30-24 measures 35 × 90 × 54.5 mm (W × H × D). The 35 mm (2SU) width is wider than the HDR-15 but narrower than the HDR-60 (52.5 mm).
What is the terminal pin assignment of the HDR-30-24?
TB1 (4 pins): Pin 1 = DC OUTPUT +V, Pin 2 = DC OUTPUT −V, Pin 3 = AC/L, Pin 4 = AC/N. AC/L is pin 3 and AC/N is pin 4 on the HDR-30 — this is the reverse of the HDR-15. Verify terminal labels before wiring.
What is the no-load power consumption of the HDR-30-24?
No-load power consumption is below 0.3W, supporting energy-efficient standby operation.
What is the operating temperature range of the HDR-30-24?
The HDR-30-24 operates from −30°C to +70°C with free air convection cooling. Derating is required above +50°C ambient.
Can the HDR-30-24 be used without connecting protective earth?
Yes. Because the HDR-30-24 is Class II double insulated, no protective earth (PE) connection is required. The plastic housing effectively prevents user contact with electrical hazards.
Does the HDR-30-24 pass LPS?
Yes. The HDR-30-24 passes LPS (Limited Power Source) certification, making it suitable for safety-critical circuits that require limited available energy under fault conditions.
What certifications does the HDR-30-24 have?
The HDR-30-24 is certified to UL62368-1, UL508, TUV BS EN/EN61558-2-16, IEC62368-1, EAC TP TC 004 and BSMI CNS14336-1. It complies with BS EN/EN61000-6-2 industrial immunity and BS EN/EN61000-3-2 Class A harmonic current requirements.
How does the HDR-30-24 differ from the HDR-30-12?
Both share the same 35 mm (2SU) housing and 30W class, but the HDR-30-24 provides 24V at 1.5A (36W) while the HDR-30-12 provides 12V at 2A (24W). The 24V model delivers higher total wattage and has a wider ripple specification (150mVp-p vs 120mVp-p), but both use the same 105–160% overload protection and ±10% adjustment windows.
Can the HDR-30-24 power several 24V sensors and a small relay bank?
Yes, if the combined steady-state current stays within 1.5A (36W). Relay pull-in current can be higher than holding current, so add the worst-case relay load to the sensor draw and verify the total before connecting. If the combined load approaches 1.5A, step up to the HDR-60-24 (2.5A) for headroom.
