Latest inversion technology ideal for 48VDC-based telecoms systems

Powersolve announces a series of Sine Wave DC/AC inverters that provides between 1000 and 4500VA from a DC input between 40 to 60VDC. This makes them ideal for 48VDC-based telecoms systems. There is a total of five models in the PJN series each designed around the latest high efficiency Sinusoidal PWM inversion technology and all incorporating an energy-saving ECO working mode. All five models provide 230VAC ±2% (±15% in ECO Mode) and offer power outputs of 1000VA, 1500VA, 2000VA, 3000VA or 4500VA. Output frequency is 50Hz ±0.5%. The 3kVA unit is available with optional N+1 redundancy. Designed for front-end maintenance, each inverter incorporates 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 and 1500VA units are housed in a 1U high 19in rack enclosure. The 2000VA and 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.
