AC TO AC POWER CONVERTER

115V/400Hz to 0-5V/400Hz 200VA Light Dimming Power Supply

Fj20The 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.

Specifications:
Input Voltage: 115 Vac 400 Hz nom., 105 to 125 Vac
  95 Vac to 130 Vac (Abnormal Range)
Input Current: 2.8 Amps typ @ FL & at 115 V input
Output Voltage: 0-5 Vac 400 Hz regulated
Output Current: 0-40 Amps continuous
Frequency: 400 Hz ± 2%
Distortion (THD): 7% max at full load & at 115 Vac input
Power: 200 Watts
Power Factor: Unity (resistive)
Overload( OL): 150% output current for 5 min.
Protection (OL): Withstands without damage or degradation load exceeding 150% to an output short circuit. Unit delivers rated output power upon removal of the overload condition
Regulation: 7% for load, 2% for line and 3% for temperature
Isolation: Output is isolated from input
Control: Output 0-5 Vac is controlled by a 0-5 Vdc voltage from the slider of an external 10K ohm pot or directly from a 0-5 Vdc voltage source
Protection (SC): Under a output short circuit condition, the input current folds back and the output current is limited to a safe value
Protection (OV): Output voltage is limited to 145 Vac maximum
Soft-Start: Minimum soft start delay of 100 mSec at full load is provided during an application of step input voltage to reduce output in rush current to the load.
Shutdown (SD): Output shuts down when input voltage is below 95(±10) Vac and above 135(±10) Vac
