ESD 50-400-125 and ESD 400-1000-400 have been delivered to Korea

In June 2020, two bidirectional DC sources habe been delivery to well-known Korean manufacturers for motor testing. The ESD 50-400-125 and ESD 400-1000-400 adopts PWM technology and two-way design, the internal resistance is adjustable. They can be used as a DC power supply or a recyclable DC load. Both of them can be operated in constant current, constant voltage, constant power and constant resistance modes between power mode and regeneration mode and provide a cost-effective solution for motor testing.
