DC/AC inverters meet 48VDC power supply demands
The PJN series of DC/AC inverters, launched by Powersolve, can provide between 1000 and 4500VA from a DC input between 40 to 60VDC, making them suitable for telecoms 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 1000, 1500, 2000, 3000 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” 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.
