TSO'd 350VA REGULATED POWER INVERTER
0-115V/400Hz 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
28 Vdc NOM., 24 to 32 Vdc
18 Vdc to 36.4 Vdc (Abnormal Range)
0.6 Amp typ at 30VA EL load at 28Vdc 0.4 Amp maximum at no load
0-115 Vac regulated
0-.26 Amps continuous
400 Hz ± 2%
5% typ at 28 Vdc @ 30VA, -.2pf load
30 VA maximum for EL panel
Zero to –0.2 leading (capacitive)
5% for load, 3% for line and 3% for temperature
Output voltage 0-115 Vac is controlled by an external 5 KW potentiometer or a 0-5 Vdc source applied at pin F.
Output is isolated from input.
Deliver 150% output current for 5 min.
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
Under a output short circuit condition, the input current folds back and the output current is limited to a safe value
Output voltage is limited to 145 Vac maximum
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 EL panel.
Output shuts down when input voltage is below 14 Vdc and above 36.4 Vdc.
