FAQ

What are the main output specifications of the Envo SC-45-12PWM?

The Envo SC-45-12PWM is a 45W constant-voltage power supply with a 12V DC output. Its rated output current is 3.75A, making it suitable for 12V LED applications that fit within that power capacity.

Is the SC-45-12PWM dimmable?

Yes. This model is described as PWM dimmable and the product description also lists a three-in-one dimming function using 0/1-10V DC, PWM signal, or resistance, with a 0-100% dimming range.

What kinds of applications is this power supply designed for?

This model is intended for LED lighting and moving sign applications. Because it is a 12V constant-voltage unit, it is best matched to products that require a 12V constant-voltage power source rather than constant-current output.

Can this power supply handle a wide AC input range?

Yes. The SC-45-12PWM has a universal AC input range of 100-265VAC, which gives it flexibility across different mains supply environments. It also includes active PFC and is rated for up to 86% efficiency.

Is the SC-45-12PWM suitable for exposed outdoor locations?

No. The SC-45-12PWM has an IP20 plastic case, so it is not intended for direct exposure to water or dust. It is generally better suited to protected indoor environments or enclosed applications where the power supply is shielded from the elements.

What operating temperature range does this model support?

The listed operating temperature range is -40°C to 60°C. That makes it suitable for demanding environments, provided the application stays within the product's specified limits.
