The AcTEC DIM12-25 is a 25W, 12V constant voltage triac dimmable LED driver, designed for smooth flicker-free dimming from leading edge or trailing edge wall dimmers. It delivers a regulated 12V DC output at up to 2.08A and dims cleanly across the full 1…100% range.

Accepting 220–240VAC mains (198–264V range, DC input compatible 176–250V DC), the DIM12-25 runs at up to 84% efficiency with a 0.95 power factor and THD of ≤25%. It carries built-in open circuit, short circuit, overload and over-temperature protection, is SELV isolated, and is rated for ambient temperatures of -20…+50°C. Housed in an IP20 plastic enclosure with push wire connections. It requires a minimum load of 9.6W to run and dim correctly.

Frequently Asked Questions

What is the AcTEC DIM12-25 designed for?

The AcTEC DIM12-25 is a 25W constant voltage LED driver for 12V lighting applications. It is intended for use where a dimmable 12V power source is needed for compatible LED luminaires.

Is this driver dimmable, and what type of dimmers does it support?

Yes, this model is a triac dimmable constant voltage driver. It supports both leading edge and trailing edge dimmers and is specified for smooth dimming from 1% to 100%.

What output does the DIM12-25 provide?

This driver provides a 12V constant voltage output with a 25W power rating. It is built for applications that require a stable 12V DC output rather than constant current LED control.

What protections are included in this LED driver?

The DIM12-25 includes protection for open circuit, short circuit, overload, and over temperature conditions. It is also specified for no-load operation, which helps support reliable use in demanding commercial lighting environments.

What input voltage range does this model accept?

This driver accepts an AC input range of 198 to 264V. That makes it suitable for use on mains power within that specified voltage window.

Can the AcTEC DIM12-25 be used in different luminaire classes?

Yes, the product is specified as suitable for class I and class II luminaires. It is also described as SELV equivalent and protection class II.

What operating environment is this driver rated for?

The stated ambient temperature range is -20°C to +50°C. This makes it suitable for installations where the surrounding temperature stays within that range.

What are the physical dimensions and warranty for this model?

The DIM12-25 measures 128 x 52 x 30 mm and weighs 0.11 kg. It also comes with a 5-year warranty period.
