480W Supplies Offer Single Or Tri Phase Inputs

Delivering power outputs up to 480W, the Model DHP480-24-1 and DHP480-24-3 DIN rail-mount power supplies provide a single-phase input from 85 to 264 Vac and a three-phase input from 340 to 575 Vac, respectively. Rated for 24V at 20A, the units specify a ripple and noise performance of less than 50 mV and adjustable output voltages from 21.6V to 28V. Other standard features include a 30-second 150% peak current capability, output status lights, remote on/off inputs, and under-voltage alarm relays. Both models meet UL508, UL60950, and EN60950 specifications and they operate at full power over a temperature range from -10°C to +60°C, derating linearly at 5% per degree above 60°C to 70°C. Single-unit prices start at $300. LAMBDA, San Diego, CA. (800) 526-2324.
