1. Overview
Standards: GB, GB/T, IEC, etc.
Scope of application: It is applicable to multi-channel high-temperature on load aging test of high-power modules such as new energy vehicle controllers, inverters, DCDC.OBC.
2. Main characteristics and technical indicators
·The temperature box, water cooling box, load cabinet (reactance and electronic load are optional) and electric control cabinet are placed separately to facilitate expansion and maintenance and meet the requirements of high-power anti-interference.
·The test conditions can be directly called out from the aging test database, with flexible configuration and convenient operation
·The working current and test voltage of electronic load can be programmed. Load current can reach 800A
·The electronic load is bidirectional, with power grid feedback and energy saving.
·The electronic load can be connected in parallel to expand the output capacity.
·One instrument cabinet controls one temperature box to provide 12 aging channels at the same time. Communication, power supply and load. Each acquisition channel is completely independent. Each aging channel test scheme can be configured arbitrarily. Including, voltage, current calibration, calibration. Temperature test, rotary transformer, CAN communication, LIN communication, etc
