50 VA Static Inverters

TSO'D 400HZ STATIC INVERTERS
50 VA

The SPC-5( ) Series static inverter utilizes solid state circuitry to convert 28 VDC to 115 VAC, 400 Hz sine wave power. Design features include pulse-width modulated square to sine wave power conversion permitting light weight and reliable operation.

The SPC-5( ) Series are capable of delivering an overload of 150% of rated current for a duration not less than five minutes under all environmental conditions.
