DC/AC inverters provide up to 4500VA and feature ECO mode
A series of sine wave DC/AC inverters that provides between 1000 and 4500VA from a DC input between 40 to 60VDC has just been made available by Powersolve. They are ideal for 48VDC – based telecoms systems and meet all relevant safety and EMC standards.
There is a total of five models in the PJN Series each designed around the latest high efficiency Sinusoidal PWM (SPWM) 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 1000, 1500, 2000, 3000 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 & 1500VA units are housed in a 1U high 19in 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.
