Introduction The VTC805 is a DC-DC voltage converter designed to convert 12 Volts DC to 24 Volts DC at up to 35 Amps of output current. It is a Common Negative design, meaning that there no isolation between the input and output and they share a common ground. The recently updated single board design incorporates proven switch-mode technology for high reliability and incorporates multiple stages of input and output filtering to reduce radiated or conducted noise to very low levels.

Operation The VTC805 is designed for simple operation. Before this unit can be put into operation, it must be properly installed and connected. For more information, see Installation. TO OPERATE THE UNIT 1. Connect the voltage converter to the load. 2. Connect the voltage converter to the power source, or if already connected, turn on the external switch installed at the power source. 3. The Power LED will glow green indicating the presence of power on the Input and Output Connections. 4.
Installation MOUNTING Mount the unit in a DRY and WELL VENTILATED location, allowing at least 1 inch of clearance around all sides for adequate cooling. INPUT CONNECTION Prior to connection, an external switch and fuse both rated for maximum input amps (100 A) should be installed at the power source. This unit’s rear panel is equipped with an Marathon ST722B2502UH Power Stud Block connector with 1/4” - 20 Studs as a DC input connection.
Paralleling Diodes Option The Paralleling Diodes Option allows multiple voltage converters to be connected in parallel to share in powering a load. To perform this function, each unit is equipped with special output isolation diodes to prevent current from one unit back feeding into another. In addition, the units’ peak output current is lowered to the continuous rating for safety purposes.
Troubleshooting This unit provides 5 LED indicators to help diagnose any problems. The following table lists the meanings of the LEDs and tips for troubleshooting the issues they indicate LED Indication OVERTEMP Indicates that the voltage converter is running too hot. The unit will shut down until it cools. There may be too many devices drawing from the converter or is it located in a poorly ventilated area. Try disconnecting some devices or remounting the unit if this persists.
