REGULATED DC TO DC POWER CONVERTER |
MULTIPLE
OUTPUT LIGHT DIMMER |
|
The LT-3XX Series is a pulse width-modulated DC to DC converter that provides regulated
multiple output power. The converter transforms an unregulated 28 VDC to a regulated and
adjustable DC output via a remote control potentiometer or voltage for voltage
controlled models.
The Model LT-3XX Series is
primarily designed to control the light intensity of incandescent bulbs in lighting
systems. For special orders any three combinations of LT-52A, LT-53, LT-70, LT-73, LT-100
and LT-103 can be supplied.

Features:
- State of the art design for regulation and
positive logic for output overvoltage protection.
- Other LT-3XX Series available in various output
voltage and power ratings in the same package, or special units can be provided for
various output combinations.
- Maximum output voltage is adjustable with an
internal trim pot.
- Designed to meet various applicable portions
MIL-STD 704 notice 3, MiL-STD-202 and MIL-T-5422F class IA.
- The Model LT-3XX Series is serviceable, small and
lightweight (42 watts per pound and 1.7 watts per cubic inch)
