Power Supply

Installation Manual

1. Introduction

The PS-C18 power supply consists of a transformer and a PCP-18
PCBA.

230 VAC, 50 Hz power is input to the transformer and is converted to
24 VAC. The 24 VAC power goes from the transformer to the PC-P18
PCBA.

If there is no 230 VAC, 50 Hz input power, the battery backup can
provide 12 VDC input directly to the PC-P18 PCBA.

The PC-P18 PCBA outputs 13.8 VDC @ 5 A for use by another device.
In addition, a LED signal is output to indicate that the output 13.8 VDC
is normal and ready for the other device.

The total current of the power supply is limited to 5A.

3. Installation and Wiring

3.1 7BInstallation

Install the power supply in accordance with article 760 of the National
Electric Code NFPA 72 as well as applicable local codes.

Circuit breaker must be close to the power supply and must be

accessible.

To install the PS-C18:

1. Mount the power supply.

2. Connect the AC power (230 VAC, 50 Hz) to the marked terminals,
“Phase” to [L] and “Neutral” to [N]. Use 18 AWG or larger for all
power connections (battery, DC output).

3. Connect the grounding to the ground terminal. Make sure to
secure the screw tightly.

4. Connect the ACU power input to the power terminal marked
“VOUT + and (-)”.

5. [Optional] Connect the battery terminal to the power terminal
marked “+VBAT”.

When the battery is not used, loss of AC results in the loss of
output voltage. When using a backup battery, it must be a UL
certified "lead acid" or "gel" type. (battery leads are included)

3.2 8BWiring

Wire the unit according to Figure 2.

Figure 2: Wiring

Use 18 AWG or larger for all power connections.
Ensure that the power-limited circuit is wired separately from the non-

power limited wiring (120/230 VAC, battery.)

4. Maintenance

For proper operation, test the unit at least once a year as described
below:

 Output voltage test:

Check DC output for proper voltage level under normal load
conditions.

 Battery test:

Check specified voltage, at both battery terminal and board
terminals marked “+VBAT and (-)” under normal load conditions.
Verify that the battery is fully charged and insure that there is no
break in the battery connection wires.

Maximum charging current under discharges is 1.2 A.

Expected battery life is five years. However, it is recomm ended
to change batteries within four years. Dispose of used batteries
according to manufacturer's instructions
