LDT720-48

LDT Series are high power switching mode power supplies with 3 phase input 340 – 550 VAC, for powers from 480 to 2400 W, covering from 12 to 170 V (model dependent). Their compact size, high efficiency and excellent reliability together with easy installation due to pluggable connectors make them fit demanding applications where compactness and high power are needed. LDT Series are Class I isolation devices suitable for SELV and PELV circuitry and are designed to be mounted on DIN rail and installed inside a protective enclosure.  3 phase AC input: 3x 340 – 550 VAC  150% overload capability  High efficiency up to 93%  Up to 60°C operating temperature with no dating  Compactness  Continuity of operation if one phase is lost (model dependent)  User settable current limitation algorithm (Hiccup or Constant Current)  Easy parallelable for power increase  Multiple protections  Low noise thermal regulated 60 mm fan  Automation  Process Control  Communication  Instrumentation Equipment LDT720 Series 2 LDT720-24 400 - 500 VAC / 520 - 725 VDC 3 23 - 28 VDC 30 A LDT720-48 400 - 500 VAC / 520 - 725 VDC 3 45 - 55 VDC 15 A Specifications are measured at 25°C, at 400 VAC, typical unless otherwise stated.
