4KW Single Phase Sinewave Inverters for Railway Applications
The PBSP-74O series are true sinewave DC/AC inverters for railway applications. They operate from a nominal 74Vdc power source and produce single phase 240Vac 50Hz sinewave power. The units can operate loads up to 4kW continuously, loads up to 5kW for up to 30 minutes, and surge loads to 12kW for up to three seconds. This high surge capability allows these sinverter to operate loads with high surge currents such as motors and microwave ovens.
The PBSP-74O series employ the latest power MOSFET switching technology combined with embedded microprocessor contorl to produce very low output distortion (less than 3% THD, at very high efficiencies (95% peak
Comprehensive protection features are included. Input overvoltage and undervoltage cutouts turn the inverter off in the event the input voltage goes outside of the nomal input voltage overloads and short circuits. Automatic overtemperature shutdown protects the inverter against high ambient temperatures.
The DC input power is switched and protected via a 100A 10kA miniature circuit breaker on the front of the unit. A 20A earth leakage MCB/RCD is also connected in series with the output of the unit
Eight variants PBSP-74O-C, -CL, -D, -G, -H,-R,- and -S are available.
