How to install the Burma AC power supply so that it can function as a protection switch?(1)

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

How to install the Burma AC Marine boost/buck voltage power supply so that it can function as a protection switch?

Since the air switch and the leakage switch do not have protective functions, when the Marine boost/buck voltage power supply is abnormal, a large number of electrical equipment will be damaged. When these accidents occur, it is only necessary to disconnect the Marine boost/buck voltage power supply when the Marine boost/buck voltage power supply is abnormal, so as not to damage the electrical equipment.

Burma The three-phase AC power intelligent protector has major electrical fault protection functions such as overvoltage, low voltage, neutral wire disconnection, short circuit, phase loss/opening, etc., and has fault identification, fault indication, voltage before closing, neutral live wire reverse connection, Zero line disconnection, phase loss/phase failure detection, remote monitoring, online parameter modification and software upgrade functions.
