1.battery charging and discharging testing Product Description
1. The battery tester is according to the international standard design, battery tester each channel has an independent constant-current source and constant-voltage source. It is used to test rechargeableas( Ni-MH battery, Ni-CD battery, Lithium-ion battery and polymer batter, etc.) pack battery, and so on.
2. Battery tester's internal electrical power supply uses the high efficiency switching power supply, the energy conservation effect isemarkable, each power tube has the independent protection circuit, guarantees the Equipment works with safety and reliability.
3. Measure adopts four wire method, decrease contact error, increase measure precision.
4. Battery tester e ach channel is independent; With high efficient cooling system, Equipment can work 24 hours with full load.
