Model and DC Output
| Complete model |
HDR-15-5; HDR-15 catalogue revision 2026-04-03. The final code identifies the nominal 5 V output. |
| Rated output |
5 V DC / 2.4 A / 12 W; current range 0–2.4 A. |
| Voltage adjustment |
4.5–5.5 V using the Vo Adj. control. Keep output current and power within the model ratings when adjusting voltage. |
| Ripple and noise |
80 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 |
±2%, including setup tolerance, line regulation and load regulation. |
| Line / load regulation |
±1.0% / ±1.0%, respectively. |
| Typical efficiency |
80% 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 12 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 |
0.5 A at 115 VAC; 0.25 A at 230 VAC. |
| Typical cold-start inrush |
25 A at 115 VAC; 45 A at 230 VAC. |
| Setup / rise at full load |
2000 / 80 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 |
110–145% 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 |
5.75–6.75 V. |
| Overvoltage response |
Shut off output voltage, clamping by zener diode. |
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.
