FAQ
What are the main electrical specs of the Envo SC-20-12PWM?
This model is a constant-voltage LED power supply rated at 20 W output. It provides 12 V output and a rated current of 0 - 1.67 A. It is designed for applications that need PWM-dimmable constant-voltage power.
Is the SC-20-12PWM dimmable?
Yes. This model supports three-in-one dimming: 0/1-10Vdc, PWM signal, or resistance. It is intended for projects where smooth dimming is important for LED lighting loads.
What dimmer types is this power supply compatible with?
This unit supports 0/1-10Vdc, PWM signal, or resistance dimming. It is not compatible with Forward phase, Reverse phase, Triac, or ELV dimmers. Buyers should confirm overall system compatibility with the exact dimming setup being used.
What kinds of applications is the Envo SC-20-12PWM suited for?
This model is suitable for LED lighting and moving sign applications. Its 20 W capacity makes it better suited to lower-power 12 V applications rather than larger lighting runs. It is positioned as a compact option where PWM dimming is required.
Can this power supply be used in damp locations?
No. This unit is rated IP20 and is suitable for indoor use only. It is not described as waterproof or intended for direct exposure to water or damp locations.
What operating temperature range does this model support?
The listed operating temperature range is -40 °C to 60 °C. That gives it a relatively wide environmental range for indoor or protected commercial applications. Buyers should make sure the final installation environment stays within that stated range.
What makes the SC-20-12PWM a good fit compared with a basic non-dimmable power supply?
Its key differentiator is three-in-one dimming support (0/1-10Vdc, PWM, or resistance). The description highlights its suitability for LED lighting and moving signs. For buyers who need dimming performance rather than just basic power conversion, this model is more purpose-built.
What warranty is offered on the Envo SC-20-12PWM?
The product features a three-year warranty. That is useful for commercial buyers who want coverage on LED power components. Warranty terms and claim handling may still depend on the seller or project location.
