Samlex America VTC605 - Manual (Page 7)

INTRODUCTION
Step up a 12 VDC battery to between 13.5 and 17.0 or 24.0 and 27.5 VDC in 0.5 VDC increments (via 3
position DIP switch), or stabilize a 12 or 24 VDC power system. Safety features include reverse input
protection, low input voltage alarm, low output voltage alarm, over temperature shutdown and alarm, and
output overvoltage crowbar. If the input voltage exceeds the regulated output voltage, the unit simply
passes the voltage through with full LC filtering and a single schottky diode drop (0.5 VDC or less). Op-
tional features include a dry contact alarm relay output, and remote panel monitoring with On/Off control.
Applications include temporarily brightening 12 volt headlights or work lights, increasing voltage into an
automotive or marine ignition system for hotter spark and/or prevention of failures due to voltage drop
during engine start, stabilizing 12 and 24 VDC power systems in marine, automotive or aeronautical
environments and more.

REMOTE CONTROL OPTION
A remote control panel may be connected to the con-
verter using a 9-pin D-connector, which attaches to
the side of the converter. The remote control panel
and D connector are part of the remote control option.
The remote control panel allows the unit to be oper-
ated remotely as well as duplicating all the diagnostic
indicators and audible alarm.
REMOTE CONNECTOR
This connector is located on the side of the unit.
Note: All switches are electronic (solid state) not mechanical relays.
