Vent Axia eDemand Voltage Controller 3 Ph. 10Amp 444167

The Vent-Axia eDemand Voltage Controller (Three Phase, 10 Amp) is built for demand-driven ventilation control of A/C speed-controllable fan systems. Suitable for a wide range of HVAC applications, this controller features quick start-up via pre-programmed operating modes and a durable IP54-rated enclosure for dependable use in commercial environments.

It offers full motor protection through thermistor connectivity and comes equipped with an LCD multifunction display for easy control and diagnostics. Two analogue sensor inputs (0 – 10V requiring separate power supply, or 0 – 20mA) allow integration with CO2, temperature, and constant pressure sensors. A 0 – 20mA manual remote speed input enables direct fan speed adjustment.

Part of Vent-Axia’s eDemand range, this controller is compatible with both single and three-phase voltage controllers and inverters. All inverter units include integrated sine filters and a shared user interface for uniform operation. The product line also features specially designed IP54-rated twin fan auto changeover panels for single and three-phase setups, complete with adjustable duty share timers for balanced ventilation performance.
