Data Sheet

See the web for current data sheet version:www.puls-power.deThis power supply is designed to meet a wide range ofapplications. Output voltage is stable with ripple andnoise below 60mVpp over the total range of up to120W. The high-efficiency flyback converter provides
for greater reliability and economy.
Multiple supplies can be used in parallel to increase system power without extra control wiring, as the current is automatically shared between units (AP155.133
only).
The design ensures immunity to disturbances according to EN 61000-4, and VDE 0160 pulses (class 2 fortotal range!). The unit is also protected against overvoltage and short-circuits. Construction and design
meet all relevant safety standards such as EN 60950,
VDE 805 and VBG 804.
48V and 60V versions are available for telecommunications and motor control applications.

The unit is constructed for 19" systems:
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
only; conductive rails would inadmissibly reduceleakage distance.
