I2C DAC Controlled Electronic Load – Battery Performance Tester

https://www.electronics-lab.com/project/i2c-dac-controlled-electronic-load-battery-performance-tester/

The project presented here is an I2C electronic load, intended for testing power supplies, solar panels, batteries, and supercapacitors. The board consists of an I2C interface DAC MCP4725, OPAMP U2 acts as V to I (Voltage to Current), OPAMP U3 measures the load current across the shunt resistor and provides 0 to 4.9V Voltage with […]

DC Electronic Load – 1A

https://www.electronics-lab.com/project/dc-electronic-load-1a/

This is a very precise Electronic Load project built using the ultra-Precision, Low-Noise OPAMP MAX44251 from Analog Devices. The project can sink current from a power source. It can be used as test gear for power supplies, chargers, solar panels, batteries, and DC-DC converters. The resistor R11 acts as a shunt, OPAMPs convert current into […]
