TSO'D
400HZ STATIC INVERTER
250 VA
The models listed below are low profile versions of our 250 VA,
400Hz TSO'D SPC-10( ) series static inverters. These inverters convert 28 VDC
electrical power from 18 VDC to 37 VDC input into monophase sinewave, regulated 400 Hz
electrical power.
Regulation of the alternating 400 Hz output is accomplished by a single integrated
PWM circuit in conjunction with a "True RMS to DC Converter" chip providing both
voltage regulation and current limiting. |
SPC-10(J) Series
|
These inverters are primarily designed to power airborne and ground instruments,
compasses, gyros, radar and navigation equipment.
