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). Op­tional 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.

IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS — This manual contains important safety and operating instructions

for the converter.
ALL CONVERTERS

Samlex America does not recommend the use of the VTC605 Series Voltage Converters in life
support applications where failure or malfunction of this product can be reasonably expected to
cause failure of the life support device or to significantly affect its safety or effectiveness. Samlex
America does not recommend the use of any of its products in direct patient care.

Examples of devices considered to be life support devices are neonatal oxygen analyzers, nerve
stimulators (whether used for anesthesia, pain relief, or other purposes), autotransfusion devices,
blood pumps, defibrillators, arrhythmia detectors and alarms, pacemakers, hemodialysis systems,
peritoneal dialysis systems, neonatal ventilator incubators, ventilators for both adults and infants,
anesthesia ventilators, and infusion pumps as well as any other devices designated as "critical" by
the U.S. FDA.

1) CAUTION — To reduce risk of injury, charge only lead acid or sealed gel cell type
rechargeable batteries. Other types of batteries may burst causing personal injury and
damage.

2) Do not expose converter to rain or snow.

3) Use of an attachment not recommended or sold by the converter manufacturer may
result in a risk of fire, electric shock, or injury to persons.

4) Do not disassemble converter; take it to a qualified serviceman when service or repair
is required. Incorrect reassembly may result in a risk of electric shock or fire.

5) To reduce risk of electric shock, disconnect converter from batteries or other DC supply
before attempting any maintenance or cleaning. Turning off controls will not reduce this
risk.

6) CONVERTER LOCATION
i) Never place converter directly above battery; gases from battery will corrode

and damage converter.
ii) Never allow battery acid to drip on converter when reading gravity or filling

battery.

7) DC CONNECTION PRECAUTIONS
i) Connect and disconnect DC output connections only after setting converter

switch to off position.
