Altronix SMP5PM CTX Supervised Power Supply/Charger User Manual

SMP5PM-CTX
Supervised Power Supply/Charger
Overview:
The SMP5PM-CTX is a power limited supply/chargers that will convert a 115 VAC / 60Hz input, into a 12VDC or
24VDC power limited output, with 4 amps of continuous supply current (see specifications).

Installation Instructions:
The SMP5PM-CTX should be installed in accordance with The National Electrical Code
and all applicable Local Regulations.
1. Mount the SMP5PM-CTX in desired location.
2. Set the SMP5PM-CTX to desired DC output voltage via SW1 (see power supply voltage output selection chart).
3. Connect AC power to terminals marked [L & N], connect ground to terminal marked [G].
Use 18 AWG or larger for all power connections (Battery, DC output).
Use 22 AWG to 18 AWG for power limited circuits (AC Fail/Low Battery reporting).
Keep power limited wiring separate from non-power limited wiring
(115VAC / 60Hz Input, Battery Wires). Minimum .25” spacing must be provided.
4. Connect devices to be powered to terminals marked [+ DC --].
Note: It is good operating practice to measure and verify output voltage before
connecting devices to ensure proper operation of equipment.
*Note: Power switch is used to turn off DC output voltage. It disconnects the L (HOT) terminal
from the rest of the board. When servicing the unit, AC mains should be removed.
5. When the use of stand-by batteries are desired, they must be lead acid or gel type.
Connect battery to terminals marked [- BAT +] (battery leads included).
Use two (2) 12VDC batteries connected in series for 24VDC operation.
Note: When batteries are not used a loss of AC will result in the loss of output voltage.
6. Connect appropriate signaling notification devices to AC Fail & Low battery supervisory
relay outputs marked [N.C., C, N.O.].
