Technical content

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  Thermally regulated fan optimal cooling in harsh operating conditions  Wide output voltages range  Two phase operation possible with power derating  Automation  Process Control  Communication  Instrumentation Equipment
