Reliable Power for Access Control Systems
The YLI YP-901-12-3 power supply delivers a highly stable DC 12.8V output specifically engineered to drive magnetic locks and access controllers without voltage drops. Unlike standard switching power adapters that fluctuate under load, this heavy-duty 1.6kg controller utilizes premium imported components to maintain a persistent 1.8A current, with a momentary 3A peak to handle the sudden power draw when an electric strike or magnetic lock engages. This ensures your access control network remains online and secure, even during high-traffic periods.
Built-in Adjustable Door Delay Timer
You can easily set the door release time from 0 to 10 seconds directly on the YLI YP-901-12-3 power supply unit. This built-in time delay circuit eliminates the need to purchase and wire a separate delay module for your exit buttons or access keypads. By simply turning the internal potentiometer, administrators can customize exactly how long the magnetic lock remains disengaged after a user swipes their card or presses the exit button, providing ample time for personnel to pass through the door.
Pro Tip from Our Technicians
Always calculate the total power draw of your connected magnetic locks to ensure they do not exceed the 1.8A persistent current limit of the YLI YP-901-12-3. Our Sham Shui Po security installation experts remind you that while the unit can handle a 3A momentary spike for unlocking, running multiple heavy-duty magnetic locks that continuously draw more than 1.8A will cause the power supply to overheat. Additionally, this metal-cased unit must be installed in a dry, indoor environment away from moisture and flammable materials.

FAQ Section
FAQ Section
- Can I use this power supply to drive multiple magnetic locks at the same time?Yes, you can drive multiple locks with the YLI YP-901-12-3, provided that the combined continuous power draw of all connected locks does not exceed the 1.8A persistent current limit.
- What is the difference between momentary current and persistent current on this device?Momentary current (3A) is the maximum short burst of power the unit can provide when a lock initially activates, while persistent current (1.8A) is the maximum safe continuous power it can supply 24/7 without overheating.
- How do I adjust the door opening delay time?You can adjust the door opening delay time by using a small screwdriver to turn the internal delay potentiometer dial located on the circuit board, allowing a range from 0 to 10 seconds.
- Is this 220V power supply suitable for use in Hong Kong?Yes, the YLI YP-901-12-3 is designed with an AC 220V 50Hz input, making it perfectly compatible with Hong Kong's standard mains power grid.
- Can I install this power supply box outdoors next to the gate?No, this power supply controller is not waterproof and must be installed strictly in a dry, indoor environment to prevent short circuits and fire hazards.
