The power supply module provides self-monitoring when turned on as part of the power supply unit.
The power module provides DC voltage and DC power reproduction over a single channel.
The power module provides two modes of operation:
-
DC voltage stabilization mode – in this mode, the power supply module reproduces the set value of the DC voltage;
-
DC power stabilization mode – in this mode, the power module reproduces the set DC power value.
The power supply module provides output overcurrent protection and short-circuit protection with the ability to return to operating mode.
