Powersolve has introduced the new PJN series of DC/AC inverters which can provide between 1000A and 4500VA from a DC input between 40VDC to 60VDC making them suitable for telecom systems with a 48VDC power supply.

There are five models in the PJN Series designed around the latest high efficiency Sinusoidal PWM (SPWM) inversion technology and all incorporating an energy-saving ECO working mode.

All models provide 230VAC ±2% (±15% in ECO Mode) with models offering 1000A, 1500A, 2000A, 3000A and 4500VA power output. The 3kVA unit is available with optional N+1 redundancy. Output frequency is 50Hz ±0.5%

Other key features include front-end maintenance, alarms for battery low and inverter failure and protection against over-voltage, overload, short circuit, over temperature and utility bypass. Front panel LEDs indicate inverter, battery and fault conditions while an RS232 interface provides communications.

The 1000VA & 1500VA units are housed in a 1U high 19-inch rack enclosure. The 2000VA & 3000VA are 2U while the 4500VA comes in a 440 x 440 x 3U case. AC Input connector is via screw terminals while output connection is by IEC and screw terminals. The PJN series meets all relevant safety and EMC standards, says the company.
