Function of isolation voltage of non-isolated power supply(2)

Remote control switch circuit
The remote control switch operation of the module power supply is carried out through the REM terminal. There are two general control methods:
(1) REM is connected to -VIN (reference ground), the remote control is turned off, and VREF<0.4V is required. REM is suspended or connected to +VIN, the module works, and VREM>1V is required.
(2) REM is connected to VIN, the remote control is turned off, and VREM<0.4V is required. REM is connected to +VIN, the module works, VREM>1V is required. REM is suspended, and the remote control is turned off, that is, the so-called "suspended shutdown" (-R).
If the control is to be isolated from the input, an optocoupler can be used to pass the control signal

non-isolated power supply 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 non-isolated power supply, dcdc power module, acdc custom-make supply, high voltage input power module, customized non-isolated power supply, 3W/10W/25w/75w/100W/200W and other dcdc custom-make 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.
