DC inverter SC series

AC

The SC3 & SC3(A) are pulse width modulated dc to ac static inverters that provide regulated 400 Hz AC power up to 30 volt amperes. An internal trim pot is provided to adjust the output voltage ± 10% 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 Current 1.35 Amps typ at 28 Vdc input at FL 0.6 Amps maximum at no load Output Current SC3: .26 Amps continuous SC3(A): 1.15 Amps Continuous Frequency 400 Hz ± 1% Distortion (THD) 3% typical at FL (unity pf) at 28 Vdc 7% maximum for the input range & pf Isolation Output is isolated from input Power Factor .95 leading to .8 lagging power factor Regulation 3% for load, 2% for line and 3% for temperature Overload (OL) Deliver 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 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. Shutdown(SD) Output shuts down when input voltage is below 14 Vdc and above 36.4 Vdc. Temperature -55° C to +71° C Altitude 55,000FT Compliance FAA TSO-C73 Connector Unit mates with MS3106A14-6S Finish Gold iridite per MIL-C-5541 Class 1A Weight 1 LBS (454 grams) Size 2.00 H x 3.18 W x 5.00 L inches
