TSO'd REGULATED E/L PANEL INVERTER
0-115 Vac Electroluminescent Lamp Power Supply
The SD3 is a pulse width modulated dc to ac converter that provides regulated 0 to 115 Vac power up to 0.26 amperes for EL panel lighting. The SD3 will power approximately 160 in2 to 220 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
