The Cosel LDA30F-5 is a single-output AC-DC power supply delivering 5V DC at 6A (30W) for industrial and embedded systems. This chassis-mount unit operates across universal input voltages of 85–264 VAC (50/60 Hz) with convection cooling and minimal footprint (79 × 27 × 130 mm). Input-output isolation reaches 2000 VAC, while integrated overcurrent and overvoltage protection safeguard downstream equipment. Efficiency peaks at 78% across the input range, with line regulation of ±0.5% and ripple suppressed to 100 mVp-p. Operating temperature spans −10°C to +60°C, backed by 20 ms hold-up time at 100 VAC input.
