GPAD201M4.2-1E Customized Power Supply Description

Goldpower GPAD201M4.2-1E is a single-output customized power supply designed for demanding applications requiring a stable low-voltage rail. It supports 90–264VAC, 47–63Hz input with PF≈0.9 (220VAC, full load), and provides a regulated 4.2V DC output up to 40A (recommended 30A continuous), with ≤200W rated power and 85% efficiency. Built-in protections include output short-circuit, overcurrent/current-limit (self-recovery), and over-voltage protection. The unit meets IT equipment safety requirements and passes EMC tests (CISPR/EN Class A). Operating range is −25 to +55°C, 5–95% RH (non-condensing), altitude to 4000m (apply derating above 3000m). Baseplate cooling for installation against a heatsink/radiator shortens thermal paths and enhances reliability.

• Wide AC input: 90–264VAC, 47–63Hz; inrush ≤50A at 220VAC (cold start)
• Single 4.2V DC output, 0–40A; recommended 30A long-term, 40A peak
• Output performance: load regulation ±3%, line regulation ±2%, voltage accuracy ±5%, ripple/noise ≤200mVp-p (20MHz BW, standard test caps)
• Efficiency: 85% at 220VAC, full load; power-on delay ≤4s; rise time ≤50ms
• Protections: output OVP (5.0–5.5V), current-limit 44–60A (auto-recover), short-circuit (long-term, auto-recover)
• Environment: −25 to +55°C operating, −25 to +100°C storage, 5–95% RH; acoustic noise ≤55dB(A) @1m
• Safety/insulation: I/P–O/P 3000VAC/1min; I/P–Earth 1500VAC/1min; O/P–Earth 500VDC/1min; insulation ≥10MΩ @500VDC
• EMC: CE/RE Class A; ESD ±4kV contact/±8kV air; RS 10V/m; EFT ±2kV; Surge L-L 1kV, L-PE 2kV; CS 10V; harmonics Class A; flicker compliant
