EVD Series High Precision Bidirectional DC Power Supply
EVD Series are High Precision/High Capacity bidirectional DC power supply.

DESCRIPTION


EVD Series High Precision Bidirectional DC Power Supply is a high precision DC power supply adopting two-stage conversion architecture, featuring high dynamic response, and bidirectional energy flow. Ideal match for E-motor (controller) testing, powertrain system testing etc. For E-motor testing, EVD can be used to simulate the overload capacity, efficiency, locked-rotor current, maximum speed, overspeed, and energy recovery performance of the electric motor and controller.
