Altronix PM212 Installation Instructions - Manual

PM212 - Supervised Linear
Power Supply / Charger
Overview:
PM212 supervised linear power supply/charger converts a low voltage “AC” input to a filtered and regulated
12VDC, 1 amp continuous power limited output.
Specifications:
Input:
• 16VAC/20VA
Output:
• 12VDC output
• 1 amp continuous supply current
• Filtered and electronically regulated output
• Thermal and short circuit protection with auto reset
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.
Supervision:
• AC fail supervision (form “C” contacts)
• Low battery supervision (form “C” contacts)
Additional Features:
• AC input and DC output LED indicators
• Includes battery leads
Board Dimensions: 5.25"L x 2.75"W x 1.5"H (approximate)
Installation Instructions:
1. Connect proper transformer (16VAC, 20VA) to terminals marked [AC].
2. Measure output voltage before connecting devices. This helps avoid potential damage.
3. Connect devices to be powered to terminals marked [- DC +], carefully observing polarity.
4. When the use of stand-by batteries are desired, they must be lead acid or gel type.
Connect battery to 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.
5. Connect appropriate signaling notification devices to AC Fail & Low battery supervisory relay output
terminals marked [N.C., C, N.O.].
Note: During normal operation (A
C 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 2 amp, 120VAC/28VDC
