FAQ
What applications is the Envo EV-SNG-350-12 best suited for?
This model is designed for 12V constant-voltage lighting loads in demanding commercial and outdoor environments. It is a good fit for LED strips, signage, floodlights, and architectural lighting projects that need a regulated 12V DC supply with up to 25A output.
Is the EV-SNG-350-12 suitable for outdoor or wet-area use?
Yes. The EV-SNG-350-12 uses an IP67-rated, fully potted metal housing that is built for exposure to dust, moisture, and harsh operating conditions. Its rated operating temperature range of -40°C to +70°C also supports use in challenging indoor or outdoor environments.
What are the key electrical specifications of the EV-SNG-350-12?
This LED driver provides a constant 12V DC output with a rated current of 25A and a total power rating of 300W. It accepts 180-305VAC input, includes active power factor correction, and reaches efficiency up to 93% with power factor up to 0.98.
Is the Envo EV-SNG-350-12 dimmable?
No. This model is specified as non-dimmable, so it is intended for applications that require a fixed 12V constant-voltage output rather than integrated dimming control. That makes it more suitable for straightforward power delivery where dimming is handled elsewhere or not required.
What protection features does the EV-SNG-350-12 include for commercial installations?
The EV-SNG-350-12 includes short-circuit, overvoltage, overload, and overtemperature protection to help support reliable operation. It also includes lightning protection rated at DM 4kV and CM 6kV, which is useful for more exposed lighting environments.
How does the EV-SNG-350-12 differ from a constant-current LED driver?
The EV-SNG-350-12 is a constant-voltage driver, so it is intended for 12V DC lighting systems that are designed around a fixed output voltage. That differs from a constant-current driver, which is selected around a specific output current rather than a fixed 12V output.
What warranty and build characteristics make this model suitable for long-term projects?
This model is backed by a 5-year warranty and uses a fanless convection-cooled design, which supports silent operation and reduces dependence on moving parts. Its fully potted aluminum housing is also built for durability in demanding lighting applications.
