Power Supply DP255
Industrial systems very often require 5/10V and 24V
within one system. The dual-output DP255 can supply
controllers, sensors, actuators and other electronic
equipment simultaneously. Both outputs are stable
over the total load range, and have excellent ripple
and noise values of <50mVpp.
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 of line voltage and other disturbances (according to EM 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.
