TSO’d 30 VA STATIC INVERTER
(28 Vdc to 400Hz Sinewave)
DESCRIPTION
- 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
