A power supply and monitoring circuit for the auxiliary power supply in the power supply test of the data center computer room

Abstract

The invention belongs to the technical field of industrial tests and provides an electric fetching and monitoring circuit of an auxiliary power supply in a data center machine room power supply test. The electricity fetching and monitoring circuit is arranged between a relay gating circuit and the auxiliary power supply and is provided with an output control circuit used for achieving zero-current switching among all relays. Thus, the problem of compatibility of out-of-phase alternating current input and high-voltage direct current input is solved, test loads inputted from multiple ways are not affected by types of power supplies, and on-spot test wiring is convenient. The requirements for implementation personnel are reduced, the test loads of the same type can be used in more use occasions in a compatible mode, implementation cost is reduced, and the circuit is simple in structure, small in size and low in cost.

Description

technical field [0001] The invention belongs to the technical field of industrial testing, and in particular relates to a power-taking and monitoring circuit of an auxiliary power supply in a data center computer room power supply test.
