Instek ASR-002 - External Three-Phase Control Unit
The Instek ASR-002 is a three-phase power controller which is able to control up to 3 single-phase power supply units (ASR series only).
It effectively makes AC output conform to 1P3W/3P4W, and also turns output into 3P3W via a designated wire method.
When the selected single-phase power is greater than the capacity of 2kVA, it is suggested that the output be connected to an external terminal for safety considerations.
