IMPORTANT & SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS — This manual contains important safety and operating
instructions for the battery charger.
VOLTAGE CONVERTER PRECAUTIONS
1. Do not expose the voltage converter to rain or snow unless it is a sealed model.
2. Use of an attachment not recommended or sold by the manufacturer may result in a risk
of re, electric shock, or injury to persons.
3. Do not disassemble the voltage converter; return it to the manufacturer or an authorized
service center when service or repair is required. Incorrect reassembly may result in a
risk of electric shock or re. Voltages of up to 350 volts are present inside the voltage
converter anytime it is connected to input power, even if it is switched off.
4. To reduce risk of electric shock, unplug the voltage converter from the DC power source
before attempting any maintenance or cleaning. Turning off controls will not reduce this
risk.
5. Never place the voltage converter directly above a battery; gases from battery will
corrode and damage the voltage converter.
6. Never allow battery acid to drip on the voltage converter.

Introduction
The VTC1505 Voltage Convertery provides up to 1500 watts continuous and 1800 watts
intermittent to power one or more loads from a 110, 250 or 300 VDC source. Two positive and
two negative output connections are provided for easy connection to multiple devices. The
recently updated single board design incorporates state of the art switch- mode technology
for unmatched efciency and ultra-quiet operation. Multiple stages of ltering reduce radiated
and conducted noise to MIL461 levels.
Safety features include over-temperature shutdown, current limiting, short circuit protection
with automatic recovery, input under voltage shutdown and output over-voltage protection.
Extra features include visual indicators for low input voltage, overload and overtemperature,
dry contact output fail output and remote control connection.

Operation
To turn the unit on, simply press the Power push button. The alarm buzzer will sound and the
Low Output LED will come on briey, and then the green OUTPUT ON LED will illuminate.
The unit will provide the regulated voltage from no load to the maximum load shown in the
specications section. You may check this voltage at the output terminals of the unit with a
good digital voltmeter. As shipped from the factory, the unit is preset to the voltage listed in
the specications, but it can be adjusted by approximately +/- 5 percent. If you wish to adjust
the output voltage, rotate the output adjust potentiometer with a at blade screwdriver.
Clockwise increases the output voltage, and counter clockwise decreases it.
Digital Meter Option (V Option)
A high quality digital meter can be added to the charger (factory installed only). Both outputs
can be monitored for current and voltage. The Digital Meter option adds 3 inches to the overall
length of the unit
Steel Mill Option (S Option)
The Steel Mill Option adds a robust surge supressor to the input of the voltage converter to
protect it from the high voltage spikes that can be present in this environment.
Load Share Option (D Option)
Two or more units may be congured for load sharing if they are equipped with the optional
output isolation diodes. To conrm that your unit has these diodes, use an ohmmeter to
measure the resistance between the two positive output terminals. If the diodes are present
the terminals will measure as not connected. If the diodes are NOT present, the terminals
will measure as a short circuit. Assuming the output isolation diodes are present, connect
a one-foot piece of red wire of the appropriate gauge from each positive output terminal to
a common connection point to further assist in even load sharing. Either using the optional
digital meter display, or with a good quality clamp on ammeter, use the output voltage adjust
potentiometers to ne tune the load sharing. Please not the the maximum current is reduced
to the Continuous Rating for any units equipped with the D Option.

The relay is factory preset to fail when the low output LED and buzzer come on. Both normally
open and normally closed contacts are available on the connector. If your system detects
an alarm condition when the voltage converter is operating normally, simply move the wire
connected to Pin 1 of the dry contact terminal block to Pin 3, or vice versa as needed.
Remote Control Option
A high quality digital meter can be added to the charger (factory installed only). Both outputs
can be monitored for current and voltage. The Digital Meter option adds 3 inches to the overall
length of the unit
A remote control panel may be connected to the voltage converter using a 9-pin D-connector,
which attaches to the rear of the voltage converter. The remote control panel and D connector
are part of the remote control option. The remote control panel allows the unit to be operated
remotely as well as duplicating all the diagnostic indicators and audible alarm.
REMOTE CONNECTOR
This connector is located on the rear of the unit. Important: To prevent the possibility of High
Voltage Electrical Shock, do not power up the voltage converter unless all wiring from the unit
to the remote is securely connected. Do not remove the dust cover from the DB-9 connector if
the remote is not being used.
Dry Contact Relay

Mounting
Mount the unit and allow at least 1 inch
of clearance around the heat sink ns for
adequate cooling.
Input Connection
This unit is equipped with a 1.0 m AWG12
cable (approx. length) for connection to the
DC power source. Red or White is Positive
and Black is Negative.
Output Connection
This unit has two pairs of color coded Phoenix VDFK6 terminal blocks, 60 Amp rated. Red is
Positive and Black is Negative. Connect to the load an appropriate sized cable. AWG6 is the
recommended size for these terminals.
For 12V models, the output current capability exceeds the rating of an individual connector. If
the load is greater than 60 amps, split the output cable into two and connect half the cable to
each output terminal to ensure safe operation.
If multiple loads are connected to the voltage converter, but none are greater than 60 amps,
then share the connections to ensure that no more than 60 amps of load is connected to any
one output terminal.
Installation

Troubleshooting
This unit provides LED indicators and a buzzer to help diagnose any problems. The unit should
sound the buzzer to alert you prior to shutting itself down. You should immediately check the
indicators to determine the cause of the shutdown.
OVERLOAD Indicates that the load connected to the voltage converter exceeds the
continuous rating.
LOW OUTPUT Indicates that the output voltage is below normal because:
The current demanded by the devices connected to the unit exceeds the
maximum output current rating, causing the output voltage to drop to
maintain the current at the maximum level.
The input voltage is not high enough for unit to operate.
LOW INPUT Indicates that the input voltage is below normal because:
The input voltage is not in the correct range for proper operation of the
unit.
OVERTEMP Indicates that the Battery Charger is running too hot because:
The Battery Charger is located in a poorly ventilated area or the ambient
temperature is too high.
One or both of the cooling fans have failed. Return to an authorized
service center to have the fans replaced.
If the voltage converter gets too hot, the temperature sensor inside
the unit will turn off the outputs. After the unit cools sufciently, it
will automatically come back on. If this happens frequently,
remount the unit for increased airow so it cools better.
