TSO'D 400HZ STATIC INVERTER

250 VA

SPC 10JThe  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.

These inverters are primarily designed to power airborne and ground instruments, compasses, gyros, radar and navigation equipment.
