Voltage Booster
Introduction:
The ENFORCER voltage booster is a step-up voltage booster. When running DC voltage over long cable runs,
a voltage drops occurs. The ENFORCER voltage booster will boost the voltage to the required operating
voltage to meet the system’s needs. It is useful for CCTV DC cameras, access controls, as well as many other
applications where voltage drop is an issue.
Specifications:Installations:
1. Remove the cover by tightly pressing the terminal
block’s holes and pushing the side mounting
brackets outwardly.
2. Set the desired output voltage to 12 or 24 VDC.
See table 3. The factory default output setting is
12 VDC.
3. Turn on the power of the power supply. Connect
the output wires from the power supply to the
power input terminal blocks. See specification
chart for the power requirements.
4. Use table 2 to check the LED status for the input
and output voltage.
5. To avoid potential damage, use a voltage meter
to check if the voltage reading at the input and
output terminal blocks is correct.
Observe correct polarity.
Note: 1. Use between 16 AWG and 26 AWG wire
for the input and output terminal blocks.
2. Use the included SECO-LARM DC
pigtail connector for easy installation.
6. Connect device to the power output terminal blocks.
7. If the output voltage is low, then turn the rotary
knob clockwise to increase the voltage or counter-
clockwise to decrease the voltage.
Note: If the output voltage set by the jumper is
higher than the input voltage, then the output
voltage stays the same.
8. Replace the plastic cover on the voltage booster
and secure it in the desired location.
