TN280D  Monitor module

Module size : 19’’2U.

With LCD and LED, it allows the user to monitor the system status in real time and read all parameters including voltage, current, frequency and capacity etc. It can also record the alarm history. Meantime, it offers communication interface (RS232 or RS485) for PC software monitoring and relay dry contact.

Static transfer switch (STS)

It increased the system availability and security by automatic transfer between the inverter and AC main. By setting up the priority of operation mode, user can change the systems status of “on line mode” or “standby mode”

The on line mode will use the output power provide by the inverter and when the inverter fails, the line will switch to AC main. The transfer time is less than 4ms. In standby mode, the system power is always connected to AC main and will switch to inverter when AC main fails. The transfer time is less than 4ms preventing power interruption. 

 

1>       Integrated design with monitor and static transfer switch

2>         Working mode selectable (AC priority or DC priority )

3>         RS485 or RS232 communication port

4>         Relay dry contact

5>        Quick transfer time, typically less than 1/4 cycle
