Communication power supply

Product Description

First, an overview
TG4820 communication power supply using LED digital tube display, support 220V single-phase AC input and 220V voltage level DC input. TG4820 uses vertical installation, input and output by the integration of aviation joint, an anti reverse connection protection, support electric plug. TG4820 input and output using the integrated aviation head, all kinds of signals through the socket connection
Two, the main features
Input - AC / DC (set), wide input voltage range;
Adopt the hardware flow technology, current imbalance of less than 3%, and a simple machine;
The wind machine adopts the temperature control technology, low noise and long life fan;
The configuration of remote communication interface, four;
The perfect protection function, including input / output undervoltage protection, overvoltage protection, overcurrent protection, over temperature protection;
Having short circuit protection function, even if the long-term in a short-circuit state is not damaged;
The built-in connection reverse protection, support electric plug;
