LDT2400 Series are high power multipurpose digital power supplies
with three phase input voltage 400 – 500 VAC, delivering 2400 W of
output power, covering output voltages from 24 to 170 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.
LDT2400 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.
3 phase AC input: 400 – 500 VAC
Overload 150% (3600 W peak)
Active PFC for optimal efficiency
Active input surge suppressor for improved reliability
CPU control allows flexibility and multiple programmable features
Battery charger function included

Ripple and Noise are measured with 20 MHz bandwidth, probe terminated with a 0.1μF MKP parallel capacitor.
Pay attention, set the current limitation mode jumper on C.C. mode when connecting more units in parallel.
NOTE:
Power rating, losses, efficiency, ripple, thermal behaviour and start-up may change outside of the nominal rated input range.
