FAQ

What type of power supply is the Envo SC-45-24PWM?

The Envo SC-45-24PWM is a 45W constant voltage LED power supply with a 24V DC output. It is designed for applications that need stable 24V output and three-in-one dimming capability (0/1-10V, PWM, or resistance).

What dimming methods does the SC-45-24PWM support?

This model is described as PWM dimmable and also lists three-in-one dimming support: 0/1-10V DC, PWM signal, or resistance dimming. That makes it suitable for projects that require flexible low-voltage dimming control methods.

What applications is the Envo SC-45-24PWM suitable for?

The product description states that it is suitable for LED lighting and moving sign applications. Its 24V constant voltage output makes it relevant for systems built around 24V LED equipment.

What input voltage range does the SC-45-24PWM accept?

This power supply accepts a universal AC input range of 100-265VAC. That broad range helps it fit projects where mains supply can vary across regions or sites.

Can the SC-45-24PWM be used in demanding temperature conditions?

The listed operating temperature range is -40°C to 60°C. That gives this model a relatively wide environmental range for commercial LED power applications.

What protection features are included in the Envo SC-45-24PWM?

The product description lists short circuit, over current, and over loading protection. These built-in protections help support reliability in LED lighting power applications.

How much output current does the SC-45-24PWM provide at 24V?

This model is rated for 1.87A output current at 24V DC, with a total power rating of 45W. That places it in the compact constant-voltage category for moderate-power 24V LED loads.
