0-115V/400Hz Electroluminescent Lamp Power Supply

SD35The SD35 is a pulse width modulated DC to AC converter that provides regulated 0 to 115 Vac power up to 3.04 amperes for EL panel lighting. The SD35 will power approximately 2000 in² to 2600 in² area of a EL panel.

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

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: 28 Vdc NOM., 24 to 32 Vdc
  18 Vdc to 36.4 Vdc (Abnormal Range)
Input Current: 6.7 Amps typ at 350VA EL load at 28V
  2.8 Amps maximum at no load
Output Voltage: 0-115 Vac regulated
Output Current: 0-3.04 Amps continuous
Power: 350 VA maximum for EL panel
Power Factor: Zero to -0.2 leading (capacitive)
Frequency: 400 Hz ±2%
Distortion: 5% typ at 28 Vdc for 350VA, -.2pf load
Regulation: 5% for load, 3% for line and 3% for temperature
Control: Output voltage 0-115 Vac is controlled by an external 5 K potentiometer or a 0-5 Vdc source applied at pin F.
Isolation: Output is isolated from input
Overload(OL): Deliver 150% output power for 5 min.
Protection(OL): Withstands without damage or degradation load exceeding 150% (-.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.
Shutdown(SD): Output shuts down when input voltage is below 14 Vdc and above 36.4 Vdc.
