OMEGA MFR012 Mechanical Hygrostat

  • Adjustable Relative
  • Humidity Range
  • High Switching Capacity
  • DIN Rail Mountable OMEGA-MFR012-Mechanical-Hygrostat -02

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

Application Examples:

  • Electrical and Electronic Enclosures
  • Telecommunication Systems
  • Display Panels .
  • Ticket Dispensers
  • Automatic Teller Machines (ATM’s)
  • Access and Parking Control Systems

Note: The critical relative humidity for most components is 65%. Above 65% RH, condensation can cause malfunction of electronic equipment. Long-term, this can lead to corrosion and permanent damage of electronic components and systems.
