Adjustable Constant Current Electronic Load with 2.4-inch TFT Display and 4 Working Modes for Lithium Battery Monitoring

This product is a direct current electronic load, featuring a printed circuit board design. It has a maximum power rating of 150W and can handle up to 20A of load current, making it suitable for testing the capacity of power batteries.

The working voltage is 12VDC, powered by a 12V, 1A adapter. The load voltage range is 0-150VDC, and the load current range is 0-20A. The maximum load power is 150W, with a limit of 60W above 120V.

The wiring method utilizes a four-wire system, which is downward compatible with a two-wire system. The maximum power measurement is 999.999Wh, and the maximum capacity measurement is 999.999Ah. The cumulative timing range can display up to ddd:hh:mm:ss (days:hours:minutes:seconds).

The device offers four operating modes: CC (constant current), CV (constant voltage), CP (constant power), and CR (constant resistance). It supports overvoltage protection up to 150V, overcurrent protection up to 20A, and over-power protection up to 150W.

The low voltage discharge function, also known as limited voltage discharge, is configurable according to user needs, providing default unlimited voltage discharge. The time limit discharge function supports up to 99 hours and 59 minutes.

The electronic load features an alloy integrated silent heat sink, with automatic operation when the internal temperature reaches 40°C or the current exceeds 3A. An external NTC 3950 10K 1% temperature sensor can be connected to measure and display the temperature from 0-100°C.

The device supports Chinese and English interface switching, zeroing of total data, voltage and current no-load nulling, and voltage open calibration. Current open calibration is also supported.

Additional features include screen brightness adjustment, screen hibernation standby setting, and the ability to restore factory settings. PC software integration is not currently supported.

The item dimensions are 165 * 95 * 80mm (6.50 * 3.74 * 3.15 inches), and the weight is 400g (0.88 lb). The package dimensions are 195 * 105 * 135mm (7.68 * 4.13 * 5.31 inches), and the package weight is 625g (1.38 lb). The package contents include 1 electronic load, 1 adapter, and 1 NTC sensor.

In summary, this direct current electronic load offers a versatile set of features, including multiple operating modes, comprehensive protection mechanisms, and external temperature monitoring capabilities, making it a suitable tool for power battery testing and analysis.
