LAPS21000

ACDC power current driver system for laser applications with safety interlock

Output power from 7000 W up to 21000 W

The LAPS21000 is a high-power, modular DC power supply designed as a modular system. It can be configured to provide output powers from 7000 W up to 21000 W in single unit mode. Parallel mode is also available for higher powers. The LAPS21000 is designed with 3 x 7 kW PFC boards that feed a total of 12 x 1750 W DC/DC converters. So the system can be customised in any max 1750 W and 45 V steps.

Ideal power supply for laser applications

Each output channel can be used as a high-speed current driver with rise and fall times below 100 μs, making it an ideal power supply for laser diode bars or as an AC/DC front end to drive fibre laser diode systems.
