500 VA sine wave inverter targets severe apps

The CSI 500-2XD3-IP66 series sine-wave inverter targets transportation, mining, marine, military, telecom, oil and gas applications. It suits applications that require a rugged, waterproof, dust-proof, sand-proof, fire and explosion proof pure sine wave ac-output solution. The high frequency PWM inverters deliver 500 VA with pure sine wave output voltage. They provide 115 Vac continuous at 60 Hz or 400 Hz, or 230 Vac continuous at 50 Hz.

The inverters accept voltages of 24 Vdc (21 to 29 V), 48 Vdc (42 to 56 V), 110 Vdc (90 to 130 V), 125 Vdc (106 to 145 V) or custom. Efficiency is typically 80% at full load. High frequency ripple is less than 500 mVrms. Electronic protection includes 2,250-Vdc input/output isolation, inrush current limiting and reverse polarity protection. The units are rated for operation from -25°C to +55°C.
