What is the DAPPRA DR-75-24?

The DAPPRA DR-75-24 (SKU: PM25) is a 76.8W single-output DIN rail power supply providing 24V DC at 3.2A. It is a General Type model with a 55.5 mm wide metal/plastic step-shape housing, universal 85–264VAC input, 80% typical efficiency, and includes an FG/PE terminal for protective earth connection.

What is the input voltage range of the DR-75-24?

The DR-75-24 supports a universal AC input range of 85–264VAC (single phase) or 120–370VDC.

Is the DR-75-24 Class II or General Type?

The DR-75-24 is a General Type model. Unlike the Class II DR-15/30/60/100, it provides an FG (Frame Ground) terminal at TB1 Pin 1 and must be connected to PE (Protective Earth) for safety and EMC performance.

What is the output voltage adjustment range of the DR-75-24?

The DR-75-24 has a 21.6–28.8V output adjustment range via the front-panel +V ADJ potentiometer (±10% of 24V). This is sufficient for voltage-drop compensation without exceeding the tolerance of most 24V devices.

What is the over-voltage protection threshold of the DR-75-24?

The DR-75-24 triggers over-voltage protection at approximately 28.8–33.6V (120–140% of 24V). The output shuts down and requires re-powering to recover.

What is the overload protection behavior of the DR-75-24?

The DR-75-24 uses 105–150% 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 DR-75-24?

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 DR-75-24?

The DR-75-24 measures 55.5 × 125.2 × 100 mm (W × H × D). The 55.5 mm width is the narrowest among General Type models (DR-45 = 93 mm, DR-120 = 63 mm).

What is the terminal pin assignment of the DR-75-24?

TB1 (Input): Pin 1 = FG, Pin 2 = AC/N or DC+, Pin 3 = AC/L or DC-. TB2 (Output): Pins 1, 2 = DC OUTPUT +V, Pins 3, 4 = DC OUTPUT -V. Note that +V comes before -V on TB2 — this is opposite to the DR-45 (where -V comes first). Verify terminal labels before wiring.

What is the no-load power consumption of the DR-75-24?

No-load power consumption is below 0.5W for the DR-75-24, supporting energy-efficient standby operation.

What is the operating temperature range of the DR-75-24?

The DR-75-24 operates from −20°C to +60°C with free air convection cooling. Full load operation is specified up to +40°C ambient; derating is required above +40°C according to the derating curve.

Does the DR-75-24 require a protective earth connection?

Yes. As a General Type model, the DR-75-24 includes an FG (Frame Ground) terminal at TB1 Pin 1 and must be connected to PE (Protective Earth) for safety and proper EMC performance.

What certifications does the DR-75-24 have?

The DR-75-24 is certified to UL508 and TUV EN60950-1. It complies with EN61000-6-2 industrial immunity, EN55022 Class B EMC emission and EN61000-3-2 harmonic current standards.

How does the DR-75-24 differ from the DR-60-24?

The DR-75-24 increases output current to 3.2A (76.8W vs 60W) while narrowing the housing from 78 mm to 55.5 mm. It is a General Type model with an FG/PE terminal (DR-60-24 is Class II). TB2 order also differs — +V comes before -V on the DR-75-24. Choose DR-75-24 when the 24V load exceeds 2.5A but stays within 3.2A.

Can the DR-75-24 power a 24V relay bank and several sensors?

Yes, if the combined steady-state current stays within 3.2A (76.8W). 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 3.2A, step up to the DR-120-24 (5A).

Overview

DR-75-24 Overview

The DAPPRA DR-75-24 (SKU: PM25) is a 76.8W single-output DIN rail power supply in the DR Series, positioned as a General Type model with a protective earth terminal. It provides a stable 24V DC output at 3.2A from a universal 85–264 VAC input or 120–370 VDC input, with 80% typical efficiency and a ±10% output adjustment range of 21.6–28.8V.

At 55.5 mm wide, the DR-75-24 is the narrowest General Type model in the DR Series — narrower than both the DR-45 (93 mm) and the DR-120 (63 mm). Unlike the Class II DR-15/30/60/100, it includes an FG (Frame Ground) terminal at TB1 Pin 1 that must be connected to PE (Protective Earth). The TB2 output order is +V first (pins 1,2) and -V second (pins 3,4) — opposite to the DR-45. Protection includes short circuit, overload (105–150% constant current limiting, auto-recovery) and over-voltage (28.8–33.6V, shut-down and re-power).
