Model and DC Output

Complete model HDR-30-24; HDR-30 catalogue revision 2026-04-03. The final code identifies the nominal 24 V output.
Rated output 24 V DC / 1.5 A / 36 W; current range 0–1.5 A.
Voltage adjustment 21.6–29 V using the Vo Adj. control. Keep output current and power within the model ratings when adjusting voltage.
Ripple and noise 150 mVp-p maximum; measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors.
Voltage tolerance ±1%, including setup tolerance, line regulation and load regulation.
Line / load regulation ±1.0% / ±1.0%, respectively.
Typical efficiency 89% at the default 230 VAC, rated-load and 25°C test conditions.

The series designation is not a uniform output-power guarantee for all voltages. Use the published 36 W model rating and the input and temperature derating curves together.

Input and Timing

AC / DC input 85–264 VAC, with 277 VAC operational; 120–370 VDC, with 390 VDC operational. AC frequency: 47–63 Hz.
Typical AC current 0.88 A at 115 VAC; 0.48 A at 230 VAC.
Typical cold-start inrush 25 A at 115 VAC; 45 A at 230 VAC.
Setup / rise at full load 500 / 50 ms at both 115 VAC and 230 VAC.
Typical hold-up at full load 30 ms at 230 VAC; 12 ms at 115 VAC.
No-load consumption Less than 0.3 W.

Unless otherwise specified, the manufacturer measures parameters at 230 VAC input, rated load and 25°C ambient.

Protection

Short circuit / overload 105–160% of rated output power. Hiccup mode when output voltage is below 50% of rated voltage; constant-current limiting within 50–100% of rated output voltage. Both modes recover automatically after the fault is removed.
Overvoltage threshold 30–36 V.
Overvoltage response Shut down output voltage; re-power on to recover.

Overload thresholds describe fault protection, not a permitted continuous or peak output rating.

Cooling, Derating and Environment

Cooling / orientation Free-air convection; the published temperature curve is for vertical mounting.
Ambient temperature curve −30 to +70°C subject to derating. The curve permits 100% load from −30 to +50°C, then decreases linearly to 50% at +70°C.
Input-voltage curve At 60 Hz AC, the curve shows 80% load at 85 VAC, rising to 100% at 100 VAC; the 100% plateau continues through 264 VAC and the 277 VAC operational point. Apply this limit together with the temperature limit.
Working humidity 20–90% RH, non-condensing.
Storage −40 to +85°C; 10–95% RH, non-condensing.
Temperature coefficient ±0.03%/°C over 0–50°C, non-condensing conditions.
Operating altitude 2000 m. Overvoltage category III also applies only up to 2000 m under the listed standards.
Vibration 10–500 Hz, 2G, 10 min/cycle for 60 min on each X, Y and Z axis; mounting in accordance with IEC60068-2-6.

The general altitude footnote specifies an additional ambient-temperature reduction of 3.5°C per 1000 m above 2000 m for fanless supplies. It does not extend this model’s explicit 2000 m operating-altitude rating.

Isolation, Safety and EMC

Isolation / limited power Class II isolation and LPS (limited power source), as specified by the manufacturer.
Listed approvals UL62368-1, UL508, TUV BS EN/EN61558-2-16, BS EN/EN61558-1, IEC62368-1, EAC TP TC004 and BSMI CNS15598-1.
BIS scope BIS IS13252 (Part 1):2010 / IEC60950-1:2005 is listed for this voltage; the family’s 48 V version is excluded.
Design reference TUV BS EN/EN62368-1 is listed as a design reference, separately from the approved standards.
Overvoltage category Category III according to EN61558, EN50178, EN60664-1 and EN62477-1, up to 2000 m.
Withstand / insulation Input–output: 4 kVAC. Insulation resistance: 100 MΩ at 500 VDC, 25°C and 70% RH.
EMC emissions BS EN/EN55032 (CISPR32) and CNS15936 Class B for conducted and radiated emissions.
Harmonics / flicker BS EN/EN61000-3-2 Class A; BS EN/EN61000-3-3.
EMC immunity framework BS EN/EN55035, BS EN/EN61000-6-2 and BS EN/EN61204-3.

BS EN/EN61000-4-2: level 3, 8 kV air; level 2, 4 kV contact; criterion A. BS EN/EN61000-4-3: level 3, criterion A. BS EN/EN61000-4-4: level 3, criterion A. BS EN/EN61000-4-5: level 4, 2 kV L–N, criterion A.

The supply is a component of final equipment. Reconfirm EMC compliance in the completed equipment; component test results do not certify the entire system.

DIN Rail Installation, Terminals and Weight

Body size / case 35 × 90 × 54.5 mm (W × H × D); general drawing tolerance ±0.5 mm; case HDR-30. Width: 2 SU.
Drawing clearances The side drawing also marks a 58.4 mm depth span and 63.65 / 45.15 mm step-height references. Use the full mechanical drawing for the DIN latch and connection clearances.
Admissible DIN rails TS-35/7.5 or TS-35/15; the mechanical drawing identifies a 35 mm rail width.
Terminal assignment pin 1: +V; pin 2: −V; pin 3: AC/L; pin 4: AC/N.
Terminal torque shown on drawing Follow the supplied unit’s terminal-torque marking and installation instructions.

Refer to PDF page 8 for the exact terminal numbering and rail-latch geometry. Rail compatibility does not mean a rail is included. These HDR-30 pages do not list a separately orderable MEAN WELL rail, bracket, cover or connector accessory code.

Reliability and Manufacturer Information

MTBF reference 3670.4 K hours minimum, Telcordia SR-332 (Bellcore); 968.1 K hours minimum, MIL-HDBK-217F at 25°C. These are calculated reliability references, not a guaranteed service life.
Warranty statement The manufacturer’s catalogue lists a three-year warranty, subject to the applicable manufacturer terms.
