Feature:1. 23 pole terminal 2.5mm wire, 1 is the fire line input line, 2 is the neutral line output line, supports 12250V wide voltage input.2. Back rail slot for easy attachment to 35mm rails.3. PC material case has highquality heat resistance, high impact resistance and other physical and mechanical properties.4. Excellent electrical insulation, elongation, dimensional stability and chemical resistance. High strength.5. The purpose of the mechanical humidity controller MFR012 is to control the electric heating so that the dew point raises the relative humidity by more than 65% at a crucial time. In this way, condensation and corrosion are effectively prevented.Specification:Item Type:Humidity ControllerTechnical Data: 4% Relative Humidity ( 3% Tolerance)Allowable Air Flow Rate: 15m/SecContact Type: Conversion ContactContact Resistance: < 10mOhmService Life : >100 000 CyclesExchange Capacity: 20VAC/DC100mAVoltage And Current: 250 VAC, 5 (1) A250V 5(1)ADC 20WDDC 20WElectro Magnetic Compatibility : EN 61000-3-2, EN 61000-3-3 55014-1-2Connection: 1.5mm 2 - 3-pole terminal 2.5mm, clamping torsion 0.5Nm highest: rigid wire 2.5mm, steel strand (end ferrule with wire) 1.5mmInstallation: 35mm DIN rail, EN50022Housing: Plastic according to UL94 V - 0, light graySize:67 x 50 x 38mm / 2.64 x 1.97 x 1.5inWeight: 60 g / 2.12 oz(approx.)Operating/Storage Temperature: 0 To +60C (+32 To +140F) / -20 To +80C (-4 To +176F)Protection Type : IP20Approval: CE* At 50% Relative HumidityPackage List:1 x Humidity ControllerNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
