PM3/4/5-1B is a module comprised of DC/DC converters, which can serve as a stable and reliable power source for individual components of your system. The module is delivered in three versions with between three and five outputs of up to 200W each. On board each module is a microcontroller that monitors the status of each channel (voltage and current) and the temperature of the entire module. The module also contains an automated active cooling system. Each channel can be activated and deactivated remotely. The module communicates via UART/RS232/RS485 or CAN with a PC or a host device (e.g. SMK70-1B).

FLASH utilises two PM modules:


power3   power4


  • 4-output PM4 (called TYPE A) with output configuration:
    • ch1 - 19V/3,2A,
    • ch2 - 15V/3,3A, 
    • ch3 - 15V/3,3A,
    • ch4 - 12V/1,6A,
  • 3-output PM3 (called TYPE B) with output configuration:
    • ch1 - 12V/18A,
    • ch2 - 12V/18A,
    • ch3 - 5V/1,2A.

Both PM modules has with ultra wide input voltage range 18-50V.
