TM250A TelecomModular Inverter
For design of TM250A telecommodular inverter, there are three key parts, monitor, static and mechanicaltransfer switch. Customersare able to monitor the system status in real time and read all parametersincluding voltage, current, frequency and capacity, etc. Besides that, alarmand history are also provided. And RS232 or RS485 communication interface forPC software monitoring and relay dry contact are also available as well.
With regard to static transfer switchof TM250A telecommodular inverter, it increases security and system availability throughautomatic transfer between the inverter and AC main. As well as that, clientscan choose on line mode and standby mode by setting up operation mode priority.To be more specific, output power provided by the inverter is used in the online mode, so when the inverter fails, the line will switch to AC main within4ms. For standby mode, system power connected to AC main switches to inverterwhen AC main fails and the transfer time is less than 4ms to prevent powerinterruption.
Located into the sub-rack, the additional integrated manual mechanical bypassenables system maintenance without interrupting load power. Besides that, MTSis mechanically interlocked with the STS module to prevent the accidentalremoval of the static bypass module which could cause loss of AC voltage.
