120W and 240W DIN Rail-Mount Power Supplies with Front Panel Potentiometer
Lambda extended its DPP family of DIN rail-mount power supplies with the addition of 120W and 240W models. The DPP120 series are available with a nominal output of 12V, 24V or 48V, while the DPP240 series are available with an output of either 24V or 48V. For special applications, both series have a front panel potentiometer for adjusting the output voltage. Up to three units can be paralleled for higher power applications. Typical efficiencies reach up to 90 percent. Both models are convection cooled and can operate over a wide temperature range of -25°C to +71°C. The units are enclosed in a rugged metal case and can be mounted on either a TS35/7.5 or TS35/15 standard DIN rail. Colored LED indicators give an immediate visual confirmation of the output status. Pre-selecting the AC input voltage range is not required because both models operate continuously over an input range of 90V AC to 264V AC (via auto-select feature). Active power factor correction is incorporated, ensuring full compliance to EN61000-3-2. The series also meets EN55022 class B EMI standards (radiated and conducted), are approved to UL60950 and EN60950 specifications, are listed to UL508 and CE Marked. The new DPP120 and DPP240 series supplies are available now with prices starting at $61 and $90 each, respectively, in 100-unit quantities.
