DT30
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.

CH3: 10% load, 2% line & 3% for temp.
Minimum soft start delay of 200 mSec at full load is provided during an application of step input voltage to reduce output in-rush current.
Deliver 110% output power for 2 hours
Withstands without damage or degradation load exceeding 110% 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 125% max
Output shuts down when input voltage is below 13 Vdc and above 36±2 Vdc
Shuts down when air temperature inside unit reaches 105(±5)°C
Withstands without damage or degradation a
