4kW Laser Power Supply Module

LR36-4000WT

The LR36-4000WT is a constant-power 4kW switching power module featuring three-phase AC input (with Active PFC) and DC output.The module utilizes DSP digital control, resonant soft-switching, and advanced Three-phase Vienna PFC technology. It is characterized by high power density, a wide input voltage range, an extended operating temperature range, superior efficiency, and excellent EMC performance. Comprehensive built-in protections include input UVP/OVP alarm and protection, output OCP alarm and protection, output OVP, short-circuit protection, and over-temperature (OTP) alarm and protection. It is also designed with reserved parallel redundancy capability for multi-module system expansion.
