Altronix PM212 Supervised Linear Power Supply-Charger
Installation Guide
Overview :
Altronix PM212 supervised linear power supply/charger converts a low voltage
AC input to a filtered and regulated 12VDC, 1A continuous power-limited
output.
Specifications:
Input:
- 16VAC/20VA.
Output:
- 12VDC output.
- 1A continuous supply current.
- Filtered and electronically regulated output.
- Thermal and short circuit protection with auto reset.
Supervision:
- AC fail supervision (form “C” contacts).
- Low battery supervision (form “C” contacts).
Battery Backup:
- Built-in charger for sealed lead acid or gel type batteries.
- Automatic switchover to stand-by battery when AC Fails.
- PTC battery protection.
Additional Features:
- AC input and DC output LED indicators.
- Includes battery leads.
Board Dimensions (W x L x H approximate):
2.75” x 5.25” x 1.5” (69.9mm x 133.4mm x 38.1mm)
Installation Instructions:
-
Mount PM212 in the desired location/enclosure (mounting hardware included).
-
Connect proper transformer (16VAC, 20VA) to the terminals marked [AC].
-
Measure output voltage before connecting devices. This helps avoiding potential damage.
-
Connect devices to be powered to the terminals marked [– DC +], carefully observing polarity.
-
When the use of stand-by batteries is desired, they must be lead acid or gel type.
Connect battery to the terminals marked [– BAT +] on the unit (battery leads included).
Note: When batteries are not used, a loss of AC will result in the loss of output voltage. -
Connect appropriate signaling notification devices to AC Fail & Low battery supervisory relay output terminals marked [N.C., C, N.O.].
Note: During normal operation (AC and battery connected), the N.C. and C relay contacts will be in the closed position and the N.O. and C relay contacts will be in the open position.
These contacts are rated at 2A, 120VAC/28VDC.
LED Diagnostics:
| Red (DC) | Green (AC) | Power Supply Status |
|---|---|---|
| ON | ON | Normal operating condition. |
| ON | OFF | Loss of AC. Stand-by battery supplying power. |
| OFF | ON | No DC output. Short circuit or thermal overload condition. |
| OFF | OFF | No DC output. Loss of AC. Discharged or no battery present. |
Terminal Identification:
| Terminal Legend | Function/Description |
|---|---|
| AC / AC | Low voltage AC input (16VAC / 20VA min.). Altronix part # TP1620. |
| – DC + | 12VDC @ 1A continuous power-limited output. |
| AC FAIL N.C., C, N.O. | Used to notify loss of AC power, e.g. connect to |
audible device or alarm panel. Relay normally energized when AC power is present.
Contact rating 2A @ 120VAC / 28VDC.
Low Battery N.C., C, N.O.| Used to indicate low battery condition, e.g. connect to alarm panel. Relay normally energized when DC power is present.
Contact rating 2A @ 120VAC / 28VDC.
– BAT +| Stand-by battery connections. Maximum charge rate 200mA.
