Each layer is DC-48 power supply (-48V voltage range 38.5 ~ 72V, and there are repeated on and off input, it is recommended that the energy be fed back to AC three-phase power)

Each layer is equipped with a contactor (1 contactor can not meet the flow, one contactor every 3 stations), the single-layer module is controlled by the remote through the contactor to power on and off, the contactor repeats 200ms cycle under the maximum power flow It can't be invalid after 10000 disconnection

When running at full power, the cable flow requirement cannot be exceeded, and the cableselection needs to meet the high temperature requirements of 105 ℃ and above

The input side copper wire is routed, the copper wire guarantees the current flow at full load,the maximum input current of a single tested module is 50A

Each layer provides 12 auxiliary source interfaces with an output voltage of 12V and a current of 2A or more. The auxiliary sources are isolated from each other to supply power to the monitoring board and Huawei fans.The auxiliary source will not be powered down by the input contactor of each layer

1500W @ 120A, the current setting accuracy is ± 3%, the minimum load current is 0.5A, each channel can independently control the load current, and the load CC mode is set to a
minimum step of 0.1A

Each test slot needs to be equipped with a pair of terminals, each station is equipped with 8 output terminals (positive and negative), the terminal flow ≥20A

The internal working temperature range of the burn-in cabinet is room temperature ~ 70 degrees, and the time for heating up to 70 degrees is not more than 30min. Each temperature within the working temperature range can work for a long time. There is a tem perature control zone on every two floors, the temperature of each control zone is controlled separately, and the temperature deviation is +/- 3 degrees
