Technical content

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 isolat ion 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.  3 phase AC input 400 – 500 VAC  High efficiency and compact size  Overload 150%  Constant current or hiccup mode limitation, user settable  Low noise thermally regulated fan  72 V output model as standard  Automation  Process Control  Communication  Instrumentation Equipment
