AC-DC power module

(3) Before the installation is completed and the power is turned on, the wiring on each terminal should be checked and checked again to ensure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current values are correct. Prevent the occurrence of reverse and wrong connections.
(4) For high-power power supplies, there are generally two or more "+" output terminals and "-" output terminals. In fact, they belong to the same output electrode, but for the convenience of user wiring, they are connected together internally.
(5) The module power supply is not allowed to work at full load for a long time. The utilization rate of linear power supply should be controlled within 60%; the utilization rate of switching power supply should be controlled within 80%, otherwise it may cause early artificial failure of module power supply.

switching power supply module are used in different places, and the matching specifications do not need to be selected. For example, AD-DC power supply is isolated. Generally, the isolation breakdown voltage specified in manufacturing sites is 5000VAC to 6000VAC; Generally, the manufacturing sites of dcdc power modules specify 1500VDC to 2500VDC, which will be higher in special manufacturing industries, and 6000VDC is specified in the medical device industry. Zhuo Xuan Electronic Technology is a professional manufacturer of switching power supply module, dcdc power module, acdc DCDC converters supply, high voltage input power module, customized switching power supply module, 3W/10W/25w/75w/100W/200W and other dcdc DCDC converters supply, which can provide a stable and reliable controller voltage for the customer system, and reasonably alleviate the problem of good and bad power use caused by static electricity and surge. It is also a data collection Expected plan for common power of communication subsystem.
