Features

Standardized PLC , DI/DO, and RS-232C/USB/LAN interfaces, along with optional GPIB/RS-232C converters and external analog input control (0-10Vdc), enable PC-based or PLC-based automatic control. The standard output voltage is 310V (line voltage 537V), allowing for the reproduction of power supply environments worldwide. Furthermore, an extended output voltage of 350V (line voltage 606V) is available, enabling voltage fluctuation testing (±20%).

It comes standard with a time-delayed current limit function that corresponds to the motor's starting current. Furthermore, with an optional upgrade, it can handle instantaneous overload output up to three times the normal level, enabling testing of all types of rotating equipment.
