Product Description
The HDR20-15-30 is 230V ac power supply for DIN RAIL control cabinets. The output voltage is selectable by switch to 15 V @ 1.34 A max, 24 V @ 0.84 A max and 30 V @ 0.67 A max. Thanks to the no electrolytic capacitor (NoElko) technology, exceptional reliability is achieved. An active output overvoltage protection with overheating protection discharges the output on overvoltage conditions.
The device is resilient to typical operating failures: Input transient protection, output short circuit, open circuit, moderate input transients and moderate output transients. A green power led indicates stable operation. The device may be operated at ambient temperatures between -40°C and 50°C. Derating might be required. The device might emit switching noise when operated in standby.

Three voltages selectable by switch: 15 V at up to 1.34 A, 24 V at up to 0.84 A, and 30 V at up to 0.67 A. All three settings share the same 20 W power budget, so current limits scale inversely with voltage.
Yes — the datasheet calls out "exceptional reliability" thanks to the NoElko (no-electrolytic-capacitor) construction. Electrolytic capacitors are the primary ageing component in conventional switching supplies; removing them eliminates that wear-out mode.
Typically 50 mW (max 60 mW) at the 24 V setting with 230 V input. The <100 mW headline applies to the 24 V setting; Figure 5 shows standby rising from ~55 mW at 15 V to ~110 mW at 30 V — so the 30 V setting actually crosses the 100 mW headline at full no-load condition.
Self-recovering, not latching. Overvoltage triggers active discharge through a 66 Ω resistor, rapidly pulling down the output rail. The discharge resistor is monitored by an NTC to prevent thermal overload. The supply returns to normal operation automatically once the overvoltage condition clears.
The input accepts 207 V to 253 V AC at 49–61 Hz; N and L pins are interchangeable. The datasheet explicitly notes that polarity can be swapped without affecting operation, which simplifies wiring in retrofit installations.
Applied engineering standards: IEC 55032 plus IEC 61000-4-2, -4-3, -4-4, -4-5, -4-6, -4-7 and -4-8 — the standard EMC/immunity set for industrial control-cabinet equipment. The datasheet lists the standard numbers; sub-part scope descriptions come from the IEC standards themselves.
No — regulation stays within roughly ±2 % of nominal across the full load range (Figure 2). The 24 V setting is the flattest (100.8 % → 99.7 %); the 15 V and 30 V curves sit slightly high at light load and settle toward nominal as current rises. Spec-table tolerances are wider: ±4 % at 15 V, ±4.2 % at 24 V, ±5 % at 30 V.
