Portable Battery Capacity Tester Electronic Load Discharge

This electronic load discharge instrument combines the ElectronicTube and the actual work needs. It has designed constant current, constant resistance, constant and other working modes, and has timing and capacity statistics functions. At the same time, it uses a standard 4-wire differential pressure amplifier circuit to measure the batterysupply voltage. It is a portable electronic load discharge instrument.



Features:

4Tube independent operational amplifier drive, current balance, curb current oscillation.

4-wire voltage detection, improve voltage detection accuracy at high current, and compatible with 2-wire measurement.

Digital control, singlechip control.

PID output control, with buffer on/off function, to prevents large current impact.

With constant current, transverse resistance and constant 3 working modes.

Using the current time integral algorithm to estimate and calculate the discharge capacity.

Customized radiator ensures that each MOStube is closely connected with the radiator to improve heat dissipation.

Operation and work have buzzerprompts to prevents misoperation.

Using an independent voltage reference to improve the stability and accuracy of temperature, voltage and current detection.

Adopt Kalman filter function to improve sampling stability.

With reverse polarity protections and short circuit protections.



Note: Without professional foundation, it is not recommended to directly connect the battery or battery resistor without a protections board to the electronic load discharge instrument.
