LDT960 Series is a high power switching mode power supplies with
three phase input voltage 400 500 VAC, delivering 960 W of output
power, covering output voltages from 24 to 72 V (model dependent).
Their compact size, high efficiency and excellent reliability together
with easy installation make them fit demanding applications where
compactness and high power are needed.
LDT960 Series are Class I isolation devices suitable for SELV and
PELV circuitry (up to 48 VDC models) and are designed to be mounted
on DIN rail and installed inside a protective enclosure.
