Burn-In Testing System For Various AC-DC Large Scale High-Power Adapter

This burn-in testing system mainly applies the burn-in of various AC-DC adapters

Performance parameters

common enquiries	Capacity	Maximum feedback power of burn-in products	54KW@1000A
		Full load feedback efficiency	>85%
		Maximum power consumption at full load	<15KW
		Number of channels	A total of 6 floors, each with 12 channels of 1500W
		Number of loads	A total of 6 layers, 12 loads per layer, a total of 72 loads CP8503
	Single channel minimum load current		≤0.5A
	Available space on each floor of internal wall		Length ≥1.8m, depth ≥0.5m
	Equipment use environment		Temperature -10 ~ 55 ℃, humidity 0 ~ 95%
Input requirements	Input voltage		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)
	Switch control		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
	Input cable		When running at full power, the cable flow requirement cannot be exceeded, and the cable selection needs to meet the high temperature requirements of 105 ℃ and above
	Input terminal		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
	Auxiliary source		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
