The FJ20 is a pulse width modulated AC to AC power converter that provides regulated 0 to 5 Vac 400 Hz power up to 40 amperes. The output voltage is controlled by a slider voltage 0-5 Vdc applied at pin M from a potentiometer 10K ohm 1/2 watt to ground or directly from a 0-5 Vdc source applied at pin M.
An internal trim pot is provided to adjust the output voltage ±10% at its full clockwise position of the external pot.
Circuit protection includes low input voltage shutdown, soft start, high input voltage shutdown, output over voltage limit and output short circuit current limit.
