Description
REGULATED DC TO DC POWER CONVERTER
(Two Channel 0-5 & 5 Vdc High Power Light Dimmer)
The LT-248 is comprised of two DC to DC converters, one fixed @5Vdc and the other controllable from 0 to 5Vdc. Â The variable output portion is primarily designed to control the light intensity of incandescent bulbs in system lighting. Â The fixed output portion may be used when regulated 5Vdc up to 7.5 ampere power is required.
The variable output voltage is adjusted via a remote control rheostat 5K ohm 1/2 watt to ground.
