Electronic Load Tester DC 12V 250W 0‑20A Battery Capacity Tester Module with Digital Display

Item Type: Electronic Load TesterMaterial: PCB, aluminum alloy. Power Supply Voltage: DC 12V ± 5%Maximum Voltage: 100VConstant Current Discharge and Current Regulation Range: 0-20AWorking Mode: Single CC mode of constant current. Maximum Error of Discharge Current: 0.7%, 0.01A. Maximum Discharge Power: 250WBasic Function:1. Constant current discharge. 2. Display voltage and current simultaneously during discharge, visually reflecting the discharge situation. 3. Separate voltage and current terminals, correctly wired, can reduce the impact of voltage on line resistance. Package List：1 xElectronic Load Tester1 x Connecting Cable1 x Nut1 x WasherNote:1. Note:A. Be sure to pay attention to polarity when connecting to the target power supply. B. To reduce the influence of line resistance on the displayed voltage, two wires should be led from two output points + and ‑ to discharge the power supply. C. The power supply voltage should not exceed 15V DC. 2. Fault Causes and Solution: A. No Display on Startup: Check the polarity of the incoming line potential, the incoming line phone position 12V DC is normal and not loose. B. Power on Only Displays 000 and 000: check whether the discharge power supply and wiring polarity are normal. C. Power on Only Displays The Voltage, Adjust The Potentiometer Without Current Discharge: check whether the wiring is in poor contact, and for A+, A‑, check whether the is blown.
