Power Supply Control AC 110-240V to DC 12V 5A - Metal Boxed UPS

In this review of the Power Supply Control AC 110-240V to DC 12V 5A, the bottom line is simple: installers and small-site integrators who need a compact, regulated 12V supply with battery backup space will find it reliable and practical. The reviewer found the unit particularly useful for door access entry systems because it converts wide-range mains input to a stable 12VDC output and includes a configurable delay that helps manage lock timing. The metal boxed cabinet and built-in protection make it a straightforward choice when you want a tidy, serviceable power module for locks and access controllers.

Key Features

• Wide input range: Accepts AC 110-240VAC at 50/60Hz so it works with most mains supplies worldwide without reconfiguration.
• Stable 12V output: Provides a regulated 12VDC/5A output suitable for powering door locks, intercoms, and access control devices reliably.
• Adjustable delay: The 0 to 15s time delay knob lets installers fine tune unlocking timing to match mechanical latches and controllers.
• Direct lock control: Can directly drive both NC and NO electric locks, reducing loading on the access controller and simplifying wiring.
• Short-circuit protection: Built-in automatic protection stops output on a short to protect connected equipment and the unit itself.
• Uninterrupted design: Metal boxed cabinet with space for a backup battery gives UPS-style continuity for locks and entry gear.

Who It's For

The unit is best for locksmiths, security integrators, and DIY installers who need a compact regulated power source for VDPs, intercoms, ACS modules, and electric strikes or rim locks. The metal case and battery compartment make it a good fit where neat installation and optional backup are important.

It is not aimed at large server rooms or heavy industrial power needs; those requiring high-capacity, multi-output UPS systems should look elsewhere. Also, installers should note the recommendation to set the timer to 0s when connecting to rim locks to avoid unintended behavior.
