The Input jumper sets the unit up for voltage or current control input and the Mode jumper selects between 0-10V/0-20mA and 2- 10V/4-20mA control signals. The minimum speed preset sets the fans speed at the bottom end of the input range (Idle speed) and the maximum speed preset sets the fan speed at the top of the input range. With the Mode jumper set for 2-10V/4-20mA the fan will automatically switch off when the input falls below 0.5 volts / 1mA (Approximately) and switches on when the input rises above 1.5V / 3mA (Approximately). The unit has a soft start to prevent any sudden speed changes reducing stress on the fan. The AX-FC has a fixed 10 volt output for connection to an external potentiometer providing a stand alone fan speed control solution.Supply Voltage 210 to 250Vac 50HzControl Signal Voltage: 0-10V or 2-10V.Current: 0-20mA or 4-20mA 0-10VInput Current 1mA maximum Maximum OutputCurrent 8 AmpsStart Up Soft startMinimum Speed Adjustment 0% to 40%Maximum Speed Adjustment 60% to 100%Fuse Size 8 AmpsTerminals Rising clamp for 0.5-2.5mm² cableDimensions 83(W) x 37(H) x 74(D)mmWeight 220gmsAmbient Temperature 0˚C to 40˚C (See Dimensions and fixings)Country of Origin United Kingdom
