TEC-06 Constant Current Electronic Load Battery Capacity Tester (Single Version) Key benefits - Accurate battery capacity measurement using constant current DAC loop control so discharge current remains stable despite voltage changes. - Built-in linear electronic load removes the need for an external discharge resistor or PWM module. - Automatic capacity calculation and logging of discharge current and time provides a fast way to verify battery or power supply output capacity. - Compact bench tool suitable for hobbyists, technicians, and product validation where reliable capacity and load testing are required. What this product does and why you need it - Measures battery capacity up to 500000 mAH (500 AH) by automatically integrating discharge current over time to report ampere-hours. - Acts as an electronic load to test and verify power supply or battery output capability and to measure internal resistance with the included 4-wire clip. - Operates as a linear constant current load rather than PWM, delivering stable current for more accurate capacity and performance testing. Main features and specifications - Model: TEC-06 single version. - Maximum current: 3.5 A. - Maximum power: 16 W. - Measurement accuracy: error less than or equal to 0.5 percent. - Maximum connection voltage: 15 V. - Power-off (cutoff) voltage adjustable from 1.0 V to 12 V with 0.05 V step resolution. - Maximum detectable capacity: 500000 mAH (500 AH). - Power supply: MINI USB interface (5 V); typical current consumption within 240 mA.
