TSO’d 30 VA STATIC INVERTER
(28 Vdc to 400Hz Sinewave)
- 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
28 Vdc NOM., 24 to 32 Vdc
18 Vdc to 36.4 Vdc (Abnormal Range)
1.35 Amps typ at 28 Vdc input at FL
0.6 Amps maximum at no load
SC3: 115 Vac
SC3: .26 Amps continuous
SC3(A): 1.15 Amps Continuous
400 Hz ± 1%
3% typical at FL (unity pf) at 28 Vdc 7% maximum for the input range & pf
Output is isolated from input
30 VA maximum
.95 leading to .8 lagging power factor
3% for load, 2% for line and 3% for temperature
Deliver 150% output current for 5 min.
Withstands without damage or degradation load exceeding 150% 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.
Output shuts down when input voltage is below 14 Vdc and above 36.4 Vdc.
-55° C to +71° C
Unit mates with MS3106A14-6S
