Description

Mechanical Hygrostat • Adjustable Relative Humidity Range • High Switching Capacity • DIN Rail Mountable Description The MFR012 is designed to control the relative air humidity inside of enclosures. When connected to an enclosure heater, (de-humidifier), it will turn the heater on at the set humidity level in order to raise the dew point. This helps prevent damage and malfunction of electronic components caused by condensation and corrosion. The MFR012 can also be used to control cooling fans, warning lights or other devices. SPECIFICATIONS Adjustment Range: 35 to 95% (±3.0%) relative humidity Switching Difference (Hysteresis): Approx. 4% RH @ 50% relative humidity Permissible Air Velocity: 50 ft/sec (15 m/s) Maximum Switching Voltage: 250 Vac Attention: 250 V should only be switched in a non-condensing environment Contact Type: Change-over contact Contact Resistance: <10 mΩ Service Life: 100,000 cycles Minimum Switching Capacity: 100 mA @ AC/DC 20 V Maximum Switching Capacity: 5A @ AC 230V (resistive load), 1.0A @ AC 230V (inductive load at cos j = 0.8); DC 20W EMI/EMC Compliance: EN 55014-1-2, EN 61000-3-2, EN 61000-3-3 Connection: 3-pole terminal, 3 x AWG 14 max [2.5 mm2 (0.1 in2 Mounting: Clip for 35mm (1.4") DIN rail (EN 50022) Dimensions: 67H x 50W x 38 mmD (2.64 x 1.97 x 1.5") Housing: Clip for 35mm DIN rail (EN 50022) Weight: 60g (2oz) Operating Temperature: 0 to 60°C (32 to 140°F) Storage Temperature: -20 to 80°C (-4 to 176°F) Protection Type: NEMA 2 (IP20) Application Examples: • Electrical and Electronic Enclosures • Telecommunication Systems • Display Panels • Ticket Dispensers • Automatic Teller Machines (ATM’s)
