MANUAL
EVT-PB1-L05Q
Video, Power and Data Balun
with Voltage Converter
Transmit video up to 2,000’ over Cat5
Selectable 5/12/24VDC output via jumper
Regulated and filtered output.
Output current protection – 500mA
Built-in overload protection.
Dual-colored LED power output indicator:
Red: 5/12VDC
Blue: 24VDC

The ENFORCER EVT-PB1-L05Q Video, Power and Data (VPD) Balun with Voltage Converter
combines the flexibility of a VPD Balun with the ability to convert AC or DC voltage for use in low
voltage DC applications. The VPD balun with voltage converter changes 12/24VAC/VDC input
voltage to a regulated 5/12/24VDC adjustable output voltage. Converted DC power is regulated to
provide stable power suitable for voltage sensitive cameras.

1. Run UTP cable to the camera where the VPD balun is being installed.
2. Remove the cover by simultaneously pressing down on the top cover, and lifting up on the side
mounting tabs. This will release the tight seal between the top and bottom covers.
3. Set the desired output voltage using the selection jumper according to table 1 below.
4. Connect the output wires from the power supply to the power input terminal blocks on the VPD
balun. Observe correct polarity.
5. Apply power and use table 2 and 3 below to check the status of the input and output voltages.
NOTE: To avoid potential damage, use a voltage meter to ensure proper voltage is
present at the input and output terminal blocks. Observe correct polarity.
6. Connect the camera to the DC plug on the balun.
7. If the output voltage is low, then turn the rotary knob clockwise to increase the voltage or
counter-clockwise to decrease the voltage.
8. Connect the video input male BNC input in from the VPD Balun to the camera.
9. If using a RS-485 controlled camera, connect the data in wires to the camera.
10. Using the remaining terminal blocks, connect the data and video wires to the balun according to
Figure 1.
IMPORTANT: Correct polarity must be observed on all connections.
11. Replace the cover on the voltage converter.

Troubleshooting:
PITSW1
Output voltage is low/high
Check output voltage jumper settings.
Check output voltage adjustment.
Check input voltage to make sure it meets the input
requirements
Green input LED not on
Check input power connections with multimeter to verify
correct input voltage
Blue/red output LED not on
Check to see if the load exceeds the maximum limit
Temporarily disconnect power input and output wires for 30
seconds before connecting
