115V/400Hz to 0-115V/400Hz Electroluminescent Lamp Power Supply


The FD15 is a pulse width modulated AC to AC power converter that provides regulated 0 to 115 Vac 400 Hz power up to 1.3 amperes for EL panel lighting . The FD15 will power approximately 750 in² to 1000 in² area of a EL panel.

The output voltage is varied by a slider voltage 0-5 Vdc applied at pin E from an external potentiometer 10K ohm 1/2 watt to ground or directly from a 0-5 Vdc voltage source applied to pin E.

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.  


Input Voltage: 115 Vac 400 Hz nom., 105 to 125 Vac
  95 Vac to 130 Vac (Abnormal Range)
Input Current: .73 Amps typ at 150VA EL load at 115V
Output Voltage: 0-115 Vac 400 Hz regulated
Output Current: 0-1.3 Amps continuous
Power: 150 VA
Power Factor: Zero to -0.2 leading (capacitive)
Frequency: 400 Hz ± 2%
Distortion: 3% typ at 75VA & 7% typ at 150VA
Regulation: 7% for load, 3% for line and 3% for temperature
Isolation: The output is isolated from the input
Control: Output 0-115 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
Overload(OL): 150% output power for 5 min.
Protection(OL): Withstands without damage or degradation a load exceeding 150°/O (-.2pf) to an output short circuit. Unit delivers rated output power upon removal of the overload condition
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 EL panel.
Shutdown(SD): Output shuts down when the voltage is below 95(±10) Vac and above 135(±10) Vac
