Data Sheet

See the web for current data sheet version:www.puls-power.deThis unit is designed to supply a variety of popular voltages for high-power rack-mounted applications. The
output voltage is stable with ripple and noise below
120mVpp over the total range of up to 240W. The
high-efficiency flyback converter provides for greater
reliability and economy.
The design ensures line disturbance immunity according to EN 6100-4, and VDE 0160 pulses (class 2 overthe total range!). The unit is also protected against
over-voltage and short-circuits. Design and construction meet all relevant safety standards, such as EN
60950, VDE 805 and VBG 804.
The 48V and 60V versions are available for telecommunications and motor control applications.

Ensure that pin 4 of H15 connector is on top. For
other installation considerations consult yourrepresentative. Ensure free air flow.
Important: Use non-conductive (plastic) guide rails
