300 VA

spc 30The SPC-30( ) Series static inverter utilizes solid state circuitry to convert 28 VDC to 115 VAC, 400 Hz sine wave power. Design features include SINE to SINE AC power amplification resulting in minimum weight and low levels of EMI emissions

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

The SPC-30( ) has remote "on-off" provisions. By completing a connection to ground, the unit will turn "on." This feature eliminates the need for a heavy and expensive "on-off" solenoid or actuator.
