Overview
HDR-30-12 Overview
The DAPPRA HDR-30-12 (SKU: SD92) is a 24W single-output ultra-slim DIN rail power supply in the HDR Series. It provides a stable 12V DC output at 2A from a universal 85–264 VAC input, with 88% typical efficiency and a ±10% output adjustment range of 10.8–13.8V. The “30” refers to the power class; the 12V model is current-limited at 2A, giving 24W total.
At 35 mm (2SU) wide, the HDR-30-12 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 (15–18V, shut-off with zener clamping). Ripple is 120mVp-p and no-load consumption is below 0.3W.

HDR-30-12 FAQ
What is the DAPPRA HDR-30-12?
The DAPPRA HDR-30-12 (SKU: SD92) is a 24W single-output ultra-slim DIN rail power supply providing 12V DC at 2A. It features a 35 mm (2SU) plastic step-shape housing, Class II double insulation (no grounding required), LPS certification, and 88% typical efficiency.
What is the input voltage range of the HDR-30-12?
The HDR-30-12 supports a universal AC input range of 85–264VAC (277VAC operational) or 120–370VDC (390VDC operational).
Why is the HDR-30-12 rated 24W instead of 30W?
The "30" refers to the power class. The 12V output is limited to 2A, giving 12V × 2A = 24W. The 15V/24V/48V models in the same HDR-30 housing deliver 30W/36W/36W at lower currents. The 12V model operates at lower total wattage because of the 2A current limit chosen for this output voltage.
What is the output voltage adjustment range of the HDR-30-12?
The HDR-30-12 has a 10.8–13.8V output adjustment range via the front-panel +V ADJ potentiometer (±10% of 12V). This window is sufficient for voltage-drop compensation without exceeding the tolerance of most 12V devices.
What is the over-voltage protection threshold of the HDR-30-12?
The HDR-30-12 triggers over-voltage protection at 15–18V (125–150% of 12V). 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-30-12?
The HDR-30-12 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-30-12?
The maximum ripple and noise is 120mVp-p, measured at 20MHz bandwidth with a 0.1μF and 47μF parallel capacitor.
What are the dimensions and weight of the HDR-30-12?
The HDR-30-12 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-30-12?
TB1 (4 pins): Pin 1 = DC OUTPUT +V, Pin 2 = DC OUTPUT −V, Pin 3 = AC/L, Pin 4 = AC/N. Note that AC/L is pin 3 and AC/N is pin 4 on the HDR-30 — this is the reverse of the HDR-15 (AC/N pin 3, AC/L pin 4). Verify terminal labels before wiring.
What is the no-load power consumption of the HDR-30-12?
No-load power consumption is below 0.3W, supporting energy-efficient standby operation.
What is the operating temperature range of the HDR-30-12?
The HDR-30-12 operates from −30°C to +70°C with free air convection cooling. Derating is required above +50°C ambient.
Can the HDR-30-12 be used without connecting protective earth?
Yes. Because the HDR-30-12 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-30-12 pass LPS?
Yes. The HDR-30-12 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-30-12 have?
The HDR-30-12 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-30-12 differ from the HDR-15-12?
The HDR-30-12 doubles the output current to 2A (24W vs 15W) and widens the housing from 17.5 mm (1SU) to 35 mm (2SU). It also has a wider overload protection window (105–160% vs 110–145%) and slightly higher efficiency (88% vs 85%). Choose the HDR-30-12 when the 12V load exceeds 1.25A but stays within 2A.
