12V 5A Linear Access Control Power Supply: overview
PW-110 is a 12 V DC, 5 A linear power supply for access control doors and building intercom systems. Besides powering locks and readers, it acts as a simple lock power controller: a PUSH input accepts an exit button, a CONTROL input takes a ±5 to ±15 V signal from an access controller, and NC and NO outputs feed fail-safe or fail-secure locks.
Linear regulation keeps output ripple at or below 100 mV, and the gray steel case measures 182 × 79 × 62 mm for mounting above the door or in a riser closet. Overloads and short circuits trip a self-resetting protective element: the output shuts off, and once the fault is cleared and the element has cooled for about 10 minutes, the supply returns to normal.
Input is 220 V AC ±20%, so this model is meant for 220–240 V mains regions; for 110/120 V sites, the PW-130 power box accepts 100–260 V AC. There is no battery charging circuit, so specify the PW-130 with its optional battery, or an upstream UPS, where doors must stay powered during outages.
Integration notes
The NC and NO lock terminals carry an unregulated 17 V output, and the C/NO contact is rated for a 1.5 A load; the regulated DC 12 V terminal is rated for 1.2 A. Check each lock's voltage tolerance before using the NC/NO terminals, and size the total load with 25–50% headroom. Operating temperature is –20 to +50 °C.

Where the PW-110 is used
- Powering a maglock or drop bolt plus reader at a single controlled door
- Standalone exit-button doors where the supply switches the lock directly
- Building intercom and door-entry panels in 220–240 V mains regions
PW-110 FAQ
Can PW-110 run on 110/120 V mains?
No. The input is 220 V AC ±20% (about 176–264 V AC). For 110/120 V sites, the PW-130 power box accepts 100–260 V AC.
Does it charge a backup battery?
No. There is no charging circuit or battery terminal, so use an upstream UPS or the PW-130 enclosure with its optional battery if the doors need backup power.
How does it release a lock without a controller?
Wire an exit button to the PUSH input and the lock to the NC or NO output that matches its fail-safe or fail-secure mode. A controller can trigger the same outputs through the CONTROL input with a ±5 to ±15 V signal.
What happens after a short circuit?
The output shuts off to protect the supply. Clear the fault, allow about 10 minutes for the protective element to cool, and the supply resumes normal operation.
How many locks can it power?
Plan against the terminal limits as well as the 5 A rating: 1.5 A on the lock contact and 1.2 A on the DC 12 V terminal. Send us your lock models and we will check the load.
