Key Features 4 Load Modes: The four load modes including CC, CV, CW, and CR that can be operated synchronously online can meet your testing demands. Different Test Functions: The functions of voltage far-end measuring, auto testing, 10KHz dynamic testing, battery capacity testing, battery internal resistance testing, and overcurrent protection point/ time testing can meet your testing demands. Digital Control Mode: The digital control mode makes it have high precision and good stability to ensure accurate test results. Switchable Voltage: The voltage can be switched between AC110V and AC220V, allowing this machine to be used under different voltages. Easy to Use:The clear interface and one-button switch make operation easier. Multiple Protections: Over voltage protection, over current protection, over power protection, over temperature protection, and input positive and negative transposition protection can ensure your safe use. Application It can be widely applied to product testing and aging in LED lighting, power source, charger, and accumulator.
