TSO & MIL Qualified
Multi-Channel DC/AC Power Converter
(0-5 Vdc, 0-28 Vdc & 0-115 Vac Three-Channel Dimmer Unit)
Description:
The DT30 is a pulse width modulated DC to DC/AC converter that provides regulated three-channel outputs, 0-5 Vdc / 0-20A, 0-28 Vdc / 0-4.3A and 0-115 Vac (400 Hz) / 0-1.04A.
Each output voltage is controlled independently by a slider voltage 0-5 Vdc from separate potentiometers 10K ohm 1/2 watt to ground or directly from a separate 0-5 Vdc voltage source. An internal trim pot is provided to adjust each output voltage ±5% at its full clockwise position of the external control pot.
Circuit protection includes low input voltage shutdown, soft start, high input voltage shutdown, output over voltage limit and output short circuit current limit. The DT30 is qualified to the rugged military requirements of MIL-Std-810C/D, MIL-STD-108E and MIL-STD-461B.
