Power Test System

Dual Channel Cycling Station

The ABC-150 was originally developed to support the design and development of the drivetrain and subsystems of the GM EV1, the first modern electric car. All Webasto power cycling systems are equipped with a real-time clock on the system’s control board that enables measurement of Ah and kWh during cycling.


The ABC-150 offers power up to 125kW, with a voltage range of 8 to 445VDC and a current range of ±530ADC. The ABC-150 is now the worldwide standard for the testing of advanced batteries, fuel cells, capacitors and other alternative energy technologies in the automotive, aerospace, stationary power and defense industries.

ABC-150: Unit Benefits

This state-of-the-art power system combines a 99% power factor and 92+% efficiency with dual independently controlled channels and analog control signal for precise operation. Safety features include automatic shutdown on power loss (Anti-Islanding), independent channel interlock, and load disconnect protection (camlock model). With easy front panel connections and an emergency stop button, it ensures user-friendly operation. Additionally, it offers flexible DC supply/load capabilities, fully programmable computer control, multiple interface options (manual, remote, ROS software, LabView, CAN, and 3rd party control software), remote voltage sense, and bi-directional load capability, catering to diverse applications with adaptability and efficiency.
