Voltage tolerance includes setup tolerance, line regulation and load regulation. Ripple and noise are measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Input and Protection AC input 90–264 VAC, 47–63 Hz; apply the low-input derating curve. DC input 127–370 VDC; connect positive to AC/L and negative to AC/N. Typical AC input current 2.6 A at 115 VAC; 1.7 A at 230 VAC. Typical inrush current 20 A at 115 VAC; 35 A at 230 VAC. Leakage current Less than 1 mA at 240 VAC.

Mounting complies with IEC60068-2-6. High-altitude derating For this fanless supply, reduce the allowable ambient temperature by 3.5°C per additional 1000 m above 2000 m (6500 ft). This note does not specify a maximum operating altitude. Apply input-voltage and temperature limits together. The published overload range is not a substitute for these operating limits. Dimensions, Terminals and Installation Dimensions / case 32 × 125.2 × 102 mm (W × H × D); case 221A, mechanical drawing tolerance ±1 mm. Compatible DIN rail TS-35/7.5 or TS-35/15; the drawing shows a 35 mm rail profile. The rail is for reference and is not included with the unit. Input terminal block TB1 Pin 1: FG protective earth; pin 2: AC/N or DC negative; pin 3: AC/L or DC positive. Output terminal block TB2 Pins 1–2: DC output -V; pins 3–4: DC output +V. Installation clearances For permanent full-power loading, the catalogue recommends 40 mm above, 20 mm below and 5 mm on each side. Where an adjacent device is a heat source, allow 15 mm clearance. Installation details Use the complete mechanical drawing, the supplied unit’s markings and the manufacturer’s installation instructions for the rail attachment and wiring. These model pages do not provide a separate mounting-kit, terminal-kit or connector ordering code. Do not infer that a rail or additional wiring accessory is supplied. Safety, Insulation and EMC Catalogue-listed safety UL508 and TUV BS EN/EN62368-1; EAC TP TC004 approved. The table states compliance with BS EN/EN60204-1. Withstand voltage Input–output: 3 kVAC; input–FG: 2 kVAC; output–FG: 0.5 kVAC. Insulation resistance More than 100 MΩ for input–output, input–FG and output–FG at 500 VDC, 25°C and 70% RH. EMC emissions BS EN/EN55032 (CISPR32), BS EN/EN61204-3 Class B, BS EN/EN61000-3-2 and -3; EAC TP TC020. EMC immunity BS EN/EN61000-4-2, -3, -4, -5, -6, -8 and -11; BS EN/EN55035; BS EN/EN61000-6-2 (BS EN/EN50082-2); BS EN/EN61204-3, heavy-industry level; EAC TP TC020. The supply is a component to be installed in final equipment. Reconfirm that the completed equipment meets the applicable EMC directives. Weight, Reliability and Reference Conditions Catalogue unit weight 510 g, converted from the explicit 0.51 kg PACKING reference per unit; not a measured net weight, shipping weight or carton-weight average. MTBF 2757.3 K hours minimum, Telcordia SR-332 (Bellcore); 486.2 K hours minimum, MIL-HDBK-217F at 25°C. These are reliability references, not guaranteed operating life. Manufacturer test / warranty statement The catalogue lists a 100% full-load burn-in test and three-year warranty. Applicable manufacturer terms govern warranty coverage. Default test conditions Unless otherwise specified: 230 VAC input, rated load and 25°C ambient. Applicable datasheet NDR-75-SPEC, 2025-06-09; combined NDR/EDR catalogue pages 1–4.
