FAQ

What type of power supply is the Envo SC-20-12?

The Envo SC-20-12 is a constant-voltage LED power supply rated at 12V DC output. It delivers up to 20W of power with a rated current of 1.67A, making it suitable for compatible 12V LED lighting applications.

Is the Envo SC-20-12 dimmable?

Yes. This model is TRIAC dimmable and is designed to work with both leading-edge and trailing-edge phase-cut dimmers. It is also described as offering strong compatibility and flicker-free dimming performance.

What applications is the Envo SC-20-12 intended for?

This model is intended for LED lighting and moving sign applications that require a 12V constant-voltage power supply. Its 20W output makes it a fit for lower-power indoor commercial or residential lighting uses within its rated limits.

Can the Envo SC-20-12 be used outdoors or in wet areas?

No. The SC-20-12 has an IP20 design and is specified as suitable for indoor installation in dry locations. It should be selected for environments where exposure to water or dust ingress is not expected.

What input range and efficiency does the Envo SC-20-12 offer?

The listed AC input range for this model is 180-250VAC. It includes active PFC and is rated for a typical full load efficiency of 80%, which can help support stable performance in compatible lighting systems.

What protection and operating temperature features does this model have?

The SC-20-12 includes protection for short circuit, overloading, and over current conditions. It is rated to operate in ambient temperatures from -40°C to 60°C, supporting use across a wide range of indoor environments.

What are the main differentiators of the Envo SC-20-12 compared with a non-dimmable 12V driver?

A key difference is its support for TRIAC dimming with both leading-edge and trailing-edge dimmers, along with flicker-free dimming performance. It also combines active PFC, indoor IP20 housing, and a compact 20W 12V format.
