Costa Rica There are three elements in the procurement of vehicle module power supply(3)
The high-voltage power module will generate a very high voltage during operation. If someone touches it, the consequences are unimaginable. In order to ensure the safety of employees and avoid safety risks, it is necessary to understand the insulation when purchasing high-voltage power supplies. Only by ensuring that the insulation is good enough, can some unnecessary troubles be avoided.
3. Make sure the Marine boost power supply has multiple certifications.
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
Unlike other parts, there are many certifications for high-quality power modules, such as ISO9001.CE.RoHS is the certification required for power modules, we choose never to suffer from this, because everything can be fraudulent, qualifications cannot be fraudulent .
In short, the high-voltage Marine boost power supply module must pay attention to the above three elements, and only by paying attention to these problems will not suffer losses, otherwise it may lead to safety risks.
