Mechanical Hygrostat

Mechanical Hygrostat MFR 012Adjustable relative humidity Change-over contact High switching capacity Easily accessible terminals Clip fixing The electromechanical hygrostat MRF 012 is designed to control enclosure heaters so that the dew point is raised when a critical relative humidity of 65% is exceeded. In this way condensation and corrosion is effectively prevented.Technical DataSwitch difference4% RH (±3% tolerance)Permissible air velocity15m/secContact typechange-over contactContact resistance< 10mOhmService life> 100 000 cyclesMin. switching capacity20V AC/DC 100 mAMax. switching capacity250 VAC, 5 (1) ADC 20WEMCacc. to EN 55014-1-2, EN 61000-3-2, EN 61000-3-3Connection3-pole terminal for 2.5mm clamping torque 0.5Nm max.: rigid wire 2.5mm, stranded wire (with wire end ferrule) 1.5mmMountingclip for 35mm DIN rail, EN50022Casingplastic according to UL94 V-0, light greyDimensions67 x 50 x 38mmWeightapprox. 60gFitting positionvariableOperarting/Storage temperature0 to +60C (+32 to +140°F) / -20 to +80C (-4 to +17F)Protection typeIP20ApprovalsVDE and UL submittedat 50% RH
