Welcome to our shop! The Electronic Load Aging Battery Capacity Tester Module is designed with high-quality components to ensure long-term stability. It features an original IR power tube, dual NMB ball bearing high-speed fan with temperature control, and an industrial large tooth radiator. The classic digital tube display is intuitive and durable, making it more resistant to high temperatures than LCD displays. The rotary encoder setting allows for simple operation and offers diverse functions. The buzzer sound prompt enhances the operating experience. With the all-parameter automatic memory function, this tester is ideal for assembling power adapter automatic aging cabinets. Rest assured that our products undergo a 100% power aging test before leaving the factory. Item Type: Electronic Load Aging Battery Capacity Tester Module Working Mode: Single mode constant current (CC) Discharge Current: 0.20-9.99A, Step 0.1A or 0.01A Maximum Discharge Current Error: 0.7%-0.01A Maximum Error in Capacity Test: 0.5A 2.5%, 2A 1.5%, 5A and above 1.2% Termination Voltage Setting Range: 1.0-25.0V, step 1V or 0.1V Discharge Voltage: 1.00-30.00V Maximum Error in Voltage Measurement: 0.8%±0.02V Maximum Power: 60W Highest Statistical Value of Battery Test: 999.9Ah or 9999Wh Positioning Hole Position: 60mmx88mm Hole Diameter 3.2mm Load Power Supply: 12V, current 0.5A or more Fan Control: Intelligent fan control Protection Function: overheat protection "otP", instantaneous overpower protection "oPP", overvoltage protection "ouP", reverse connection protection, abnormal supply voltage protection. Instructions: 1. Mode Setting: Press and hold the start and stop button to power on the tester, change the setting by turning the knob. "Fun1" is in electronic load mode, "Fun2" is the battery capacity test mode. Press the start and stop button to enter the buzzer setting. After the setting is completed, press the start and stop button again to restart the tester. 2. Electronic Load Mode: Connect the tested power supply to the test input power port, set the current and lower limit voltage through the knob, and press the start/stop switch to start the load. 3. Battery Capacity Test Mode: Fully charge the battery with a dedicated charger, connect the battery to the tester, set the discharge current and termination voltage, and press the start and stop switch to start the test. Additional Instructions: During the battery test, the discharge current and termination voltage can be adjusted at any time. The tester automatically saves the set parameters and restores them after power-off. 100% Satisfaction: Our customers are our top priority.
