Powersolve has introduced the 2UPSWI series of 19inch, 2U high, rack-mount DC/AC inverters capable of providing up to 3000W from a variety of inputs. The series comprises 20 models with DC inputs of 12V, 24V, 48V, 100V and 220V. Output is either 100 to 120V AC or 200 to 240V AC, 50 or 60Hz true sine wave and switch selectable. Every unit has a digital display to indicate VAC, Amps, watts, temperature, frequency, over and under voltage, over temperature and overload. Other features include DC input under voltage and overvoltage alarms and shutdown and RS232 interface control port with switchable baud rates for use with optional remote control unit. Inputs are via either screw terminals or heavy duty bus bars. Output is via UK, European, US, Australian or Universal AC sockets or screw terminals. The inverters can also accept an AC input of either nominal 110 or 220V so that they can be used for UPS use, with a bypass switchover time of 4 to 6ms. Operating temperature range is -20 to +50ºC and cooling is via an integral, thermostatically-controlled fan. The inverters meet all relevant safety and EMC standards.
