Lambda Adds 480W DIN Rail Power Supplies, with Choice of Single- or 3-Phase Inputs

SAN DIEGO, CA (July 13, 2005) - Lambda has introduced two 480-watt DIN rail-mount power supplies available with a choice of single- or three-phase inputs. The mid-power DHP480 series is an economical solution specifically designed for industrial applications such as process control, factory automation, and automotive manufacture.

The new power supplies are rated at 24 volts at 20 amps and feature a low ripple and noise performance of less than 50 millivolts. The output is user adjustable from 21.6 to 28 volts. Other standard features include a 30-second 150% peak current capability, output status lights, a remote on/off input, and an under-voltage alarm relay.

Model DHP480-24-1 accepts a wide single-phase input range of 85–264 volts AC and the DHP480-24-3 a three-phase input of 340–575VAC, eliminating the need for pre-selecting the AC input range prior to shipping.

Both models are approved to UL508, UL60950 and EN60950 specifications. Units are convection cooled and can operate at full power over a wide temperature range of -10°C to +60°C, derating linearly at 5% per degree above 60°C to 70°C. The supplies measure 4.92 inches high x 5.51 inches wide x 5.34 inches deep.

The DHP480 series is available now, with prices starting at $300 in single-unit quantities. More information can be found on Lambda's Web site,
