How to install the Faroe Islands AC 48V input 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 48V input power supply is abnormal, a large number of electrical equipment will be damaged. When these accidents occur, it is only necessary to disconnect the 48V input power supply when the 48V input power supply is abnormal, so as not to damage the electrical equipment.
The loss of high-power module switching power supply mainly includes four parts: high-frequency switching loss, high-frequency transformer loss, rectification loss and line conduction loss. In the application of low voltage and high current output, the rectification loss and line conduction loss account for a larger proportion. .
Faroe Islands 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.
