UL-approved power transformer.

What it is:

The EVP-124M6-P16 Dual-Output Power Supply provides both
6/12/24VDC and 24VAC outputs in one unit where a combination of
both AC & DC outputs are needed. It will simultaneously provide
3 Amps to eight 6/12VDC outputs and 3 Amps to eight 24VAC outputs.
For 24VDC application it can only provide 1.5Amp.

Note before installation:

The EVP-124M6-P16 Power Supply is not waterproof or weatherproof.
Therefore, it must be mounted indoors where it cannot be exposed to
rain or other moisture.

Installation must be done by qualified personnel, and should
conform to local and all other applicable codes.

Installation:

1. Find a good location for the enclosure - The enclosure should be
mounted where it is out of sight and protected from moisture and
the weather, but where it can be serviced by an authorized
technician.

NOTE:

mounted has adequate ventilation. Otherwise, heat buildup inside
the enclosure could damage the electronic parts or cause the PTC
fuses to trip needlessly.

2. Determine how the main power line and power cables to the CCTV
cameras will be run -- The enclosure has knock-outs on the side,
top, bottom, and rear panels for running cables. See Fig. 1.

NOTE:

they should be protected by an armored cable sleeve.

3. Connect the main power cord to the insulated AC terminal block
as shown in fig. 2.

4. Connect the 24VAC power input wires of the CCTV or accessories to
the PCB on the right, and connect the 12VDC power input wires to the PCB on
the left (see Fig. 2). Observe correct polarity when connecting
12VDC input wires. The terminals marked “P” are for positive wires,
and “N” are for negative wires. Each output consists of one “P”
terminal and one “N” terminal.

Run wire pairs from the PCBs through or along the wall to where the
CCTV cameras and/or accessories are mounted.

NOTE:

For best results and to minimize voltage drop, these wires

should be a minimum of 18-gauge in thickness.

5. Turn the main switch ON (one on each board). The green LED on the
PCB will light to show that power is present. The red LEDs on the
printed circuit board will light to show the status of each terminal
pair, with ON meaning that the terminal pair is working correctly.

6. Test the voltage output at the end of each VDC wire pair to see if
there is significant voltage drop. The voltage output reading of all
VDC wire pairs should approximately be the same unless a voltage
drop occurred on a certain wire pair.

When running wires from the "VDC" output PCB, voltage drop can
occur for one of three reasons:

a. The wire is too thin. That is why 18-gauge wire is recommended.

b. The wire has run a long distance. If one or more of the wire pairs

is showing significant voltage drop compared to the others,
either shorten the length of the affected wire pairs, or lengthen
the other wire pairs, to produce similar voltage output readings
on all wire pairs.

c. A large number of CCTVs and/or accessories connected to the

ST-2406-5A PCB is causing excessive power drain across all the
outputs.

7. Adjust the "VDC" voltage output of the left PCB if needed - If the
voltage output reading at the end of a VDC wire pair falls below the
minimum voltage requirement, use a screw driver to carefully turn
the potentiometer to the right which is located on the
PCB

( see Fig. 2 ). This will increase the total voltage output from

ST-2406-5A

the left PCB to compensate for the voltage drop.

NOTE:

1. The VAC output is fixed and thus cannot be adjusted.

2.

Adjusting the potentiometer affects the voltage output of

the

output terminals on the left PCB. Using a voltage

all
output in excess

of the specified voltage level of a

camera may cause damage.

8. Once the desired voltage output range of each wire pair is achieved,
turn the main switch OFF.

cameras or accessories. Double-check the specified operating
voltage of each device before connecting it to a wire pair.

NOTE:

a. The CCTVs and accessories connected to the printed circuit

boards must be capable of working with 24VAC power for AC
devices and 6/12/24VDC power for DC devices. The
EVP-124M6-P16 power supply is preset at 24VAC for the right
side PCB and 12VDC output for the left side PCB. For 6/24VDC
operation, adjust the dip switch of the

ST-2406-5A PCB

according to the chart printed on its PCB.

b. Maximum total current connected to all terminals must not

exceed the power supply's total current capacity of 6 Amps
(3 Amps per board). However if the VDC-output left side PCB is
using 24VDC, then do not connect more than 1.5 Amps on the
left side PCB.

c. As a safety measure, we recommend running the power supply

at or below 75% of its total capacity for smooth continuous
operation.

and secure it with either the provided machine screws or an
optional cam lock.
