PULS DP257.105 INTRODUCTION
Industrial systems very often require 5V and 24V within one system. The dual-output DP257 can supply controls, sensors, actuators, and other electronic equipment simultaneously. Both outputs are stable over the total load range and have excellent ripple and noise values of < 40 mVpp. Even when the 24V output is short-circuited, the 5V output continues to operate without interruption.
The most important economic benefits of this unit include the replacement of two separate conventional supplies; low weight; small size; quick single-handed installation on DIN rails (TS35). Changes in line voltage and other disturbances (according to EN 61000-4, and VDE 0160 pulses - class 2 for total load range!) are filtered and regulated by the power supply. It is also protected against over-voltage and short circuits. Isolation is equivalent to safety transformers according to VDE 0551 and meets VBG 4.
