Vent Axia eDemand Voltage Controller 3 Ph. 5Amp 444166

The Vent-Axia eDemand Voltage Controller (Three Phase, 5 Amp) is engineered for demand-based ventilation management of A/C speed-controllable fans. Designed with efficiency and protection in mind, it features pre-configured quick start modes and an IP54 enclosure for dependable operation in various installations.

This controller ensures complete motor protection through a thermistor connection and includes an LCD multifunction display for easy setup and monitoring. Two analogue sensor inputs (0 – 10V requiring an external power supply, or 0 – 20mA) provide compatibility with CO2, temperature, and constant pressure sensors. A manual remote speed adjustment input (0 – 20mA) allows for fine control of fan speed when needed.

As part of Vent-Axia’s comprehensive eDemand control range, this unit is compatible with single and three-phase electronic voltage controllers and inverters. All inverter models include integrated sine filters and share a consistent user interface for simplified operation. The range is further supported by IP54-rated twin fan auto changeover panels, suitable for both single and three-phase systems, featuring an adjustable duty share timer for balanced operation.
