REGULATED AC TO DC POWER CONVERTER
Pot Control Models: LT-252-400-4, LT-270-400, LT-2100-400
Voltage Control Models: LT-253-400, LT-253A-400, LT-273-400, LT-2103-400
These converters transform an unregulated 115 VAC 400 Hz to a regulated and adjustable DC output via a remote control potentiometer or voltage for voltage controlled models.
The LT-2XX-400 Series is a pulse width-modulated AC to DC converter that provides regulated DC power output. The LT-2XX-400 Series is primarily designed to control the light intensity of incandescent bulbs in vehicle  lighting systems. For special orders any two combinations of LT-52A, LT-53, LT-70, LT-73, LT-100 and LT-103 dimmer units may be configured in a single box.
Features
- State of the art design for regulation and positive logic for output overvoltage protection.
- Other LT-2XX-400 Series available in various output voltage and power ratings in the same package, or special units can be provided for various output combinations.
- A panel mount trim pot is provided for the voltage control series to control 0-5 VDC output via 0-3 to 0-5 VDC.
- A test jack is provided to monitor output voltage.
- Designed to meet various applicable portions MIL-STD 704 notice 3, MIL-STD-202 and MIL-T-5422F class 1A.
- The Model LT-2XX-400 Series is serviceable, small and lightweight (42 watts per pound and 1.7 watts per cubic inch)
