378-VRS with Directional lights

The Dallee VRS adjustable switching power supply can be used for many applications requiring a small output voltage when only a large voltage is available.

Since the VRS is a regulated power supply, an input voltage that varies (such as a track power transformer) can be used as the source without causing the output voltage to change. This means lights on a layout or in passenger cars will always be the same brightness regardless to the setting of an adjustable locomotive transformer.

Common Uses

  • Stationary lighting of building interiors, ceilings, and outside lights
  • Regulated lighting for street lights and marquees
  • Replacement regulator for various smoke units

Installation Instructions

  1. Attach one two pin connector to input power, such as track power.
  2. Set the voltage dial to minimum voltage and power up the input power.
  3. Use an electric meter connected to the other two pin connector to set the voltage dial to the correct output voltage.
  4. Once the correct voltage is set, turn off the input power and connect the output wires to the application requiring power.
