Abstract

The invention discloses a motor protector power supply module. An input two stage filtering module is connected with a bridge-type rectifier module. The bridge-type rectifier module, a high frequency control module, a main output module, a plus 5V output module, a plus 24V output module and plus / minus12V output module are connected with a switch transformer. An auxiliary power supply of the motor protector power supply module can use an alternating current or a direct current. An input voltage scope is wide: the alternating current is from 85V to 265V; the direct current is from 90V to 400V. Multi-group of the power supplies, such as VCC (5V), plus 5V, plus 24V and plus / minus12V, are separately output.

Description

technical field [0001] The motor protector power supply module of the invention relates to the technical field of power conversion, in particular to the technical field of power conversion for motor protection. Background technique [0002] Most of the current power supply circuits of motor protectors are single power supply, and DC / DC conversion is used for isolation between multiple outputs, the use efficiency is low, and the heat consumption is large. The auxiliary power supply is required to be AC ​​or DC, and the voltage range is strictly required. For example 10% deviation etc. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages that the power supply module outputs a single voltage, the auxiliary power supply can only be DC or AC, and the input voltage range is narrow, and design a motor with multiple isolated power outputs, AC and DC, and a wide input voltage range Protector power module. The technical solution ...
