FAQ
What type of LED application is the Envo SC-20-24 designed for?
The Envo SC-20-24 is a 24V constant voltage power supply intended for indoor LED lighting and moving sign applications. Its 20W output makes it suitable for lower-power 24V systems that need stable constant voltage operation.
Is the Envo SC-20-24 dimmable?
Yes, this model is TRIAC dimmable and works with both leading edge and trailing edge phase-cut dimmers. It is also described as offering strong compatibility and flicker-free dimming for applications where smooth light control matters.
What are the main electrical ratings of the Envo SC-20-24?
This model is rated at 20W output, 24V output voltage, and 0.83A rated current. It accepts an AC input range of 180-250VAC (or 90-130VAC) and includes active PFC with efficiency up to 82%.
Can this power supply be used outdoors or in wet areas?
No, the SC-20-24 is designed for indoor use and is specified for dry locations. It is not intended for exposure to water or wet environmental conditions.
What operating temperature range does the Envo SC-20-24 support?
This power supply is rated for operation from -40°C to 60°C. That range supports use in a wide variety of indoor commercial and industrial environments, provided the location remains dry.
What protections are built into the Envo SC-20-24?
The SC-20-24 includes protection against short circuit, over loading, and over current conditions. These built-in protections help support reliable operation in demanding LED power applications.
Why would a buyer choose the Envo SC-20-24 over a non-dimmable 24V power supply?
A key differentiator is its TRIAC dimming support, including compatibility with both leading edge and trailing edge dimmers. For projects that require phase-cut dimming and flicker-free performance from a compact 20W 24V unit, this model is better suited than a basic non-dimmable supply.
