Single-stage, variable speed control

Product Overview

The SSV-DC is a single-stage, variable speed control which automatically controls the speed of connected fans based on the temperature in the facility; temperatures ranging from -13⁰F to 125⁰F (-25⁰C to 51⁰C). It is designed to control the speed of up to 10 fans within 500’ of the controller. The SSV-DC control is compatible with all VES-Artex circulation and exhaust fans using VES-Artex wired VFDs.

Each control features two LED displays which show the temperature, signal output, alarm codes, and programming information. Purchase of one control includes a 6” temperature probe available with a 30’ or 150’ cable length

This Phason control is a great, economic choice. It’s a great first-step for simple automation.
