What is the output of the Thinkwise PSTW-12V-20W power supply?

This model provides a 12V output with a 20W power rating and a rated current of 1.67A. It is designed as a constant-voltage power supply for suitable 12V lighting applications.

What types of applications is the PSTW-12V-20W suitable for?

The PSTW-12V-20W is intended for interior low-voltage lighting uses such as LED strip lighting and steplights. It is a compact option for projects that need a 12V constant-voltage supply within its rated 20W capacity.

Is this power supply dimmable?

No, this model does not include a dimming control function. If your project requires dimming, you would need to confirm that the wider system is designed around a separate compatible dimming approach.

What operating temperature range is this model rated for?

The Thinkwise PSTW-12V-20W is rated for operation from -20°C to 50°C. That makes it suitable for a range of indoor environments, provided the surrounding conditions stay within that temperature window.

What makes this model different from higher-wattage 12V power supplies?

This unit is a lower-power 12V option rated at 20W and 1.67A, which suits smaller lighting loads rather than larger multi-fixture runs. Buyers comparing models should focus on matching the required 12V output and total load to the unit's rated capacity.

What warranty is offered on the PSTW-12V-20W?

This model is listed with a 3-year warranty period. That can be useful for trade and project buyers who need a defined warranty term for maintenance planning and procurement review.
