How It Operates
This intuitive DC motor controller includes a user-friendly interface with a rotating control knob and LED indicators. The unit monitors temperature and adjusts output voltage accordingly, sending stop/start signals via the disconnect relay when required. Even during power interruptions, the system retains settings for uninterrupted operation.
Frequently Asked Questions
- Is this a direct replacement for the SSV-DC? Yes, it offers updated features and improved control.
- How many devices can it manage? Typically up to 10, depending on load and wire length.
- Does it include manual override? Yes, accessible via software controls.
- Can I shut down fans with the relay? Not directly—it sends a signal to the controlled device rather than interrupting power.
- Why does my fan still run at 0%? Some devices operate at low signal levels; the relay ensures complete shutdown.
Compatible Accessories
- FanDRIVEs: Adjust fan speeds with the 0–10 VDC output (models FD-2-7 and FD-1-14)
- 3K Series Temperature Sensors: Support 4-zone temperature averaging with long cable runs
