800W 400W High Power Discharge Instrument Electronic Load BUS

Ship with 12V power supply.

This load is an adjustable constant current linear load. Users can set the discharge current according to their needs.

Can be used for battery capacity detection, power aging, etc.

The load can be used as a stand-alone machine, or it can be controlled by a computer host computer, and the discharge curve can be drawn through the host computer.

The upper control is controlled by Modbus bus, and each bus can control up to 99 loads.

Our store provides English host online control software for free. Communication is the standard Modbus protocol.
