Application
The Mechanical Hygrostat controls relative air humidity inside an
enclosure to prevent condensation and corrosion that can damage
components. It can also be connected to an enclosure heater, cooling
fans, warning lights or other devices.
The critical relative humidity (RH) level for most components is 65
percent. Above 65 percent RH, condensation can form and cause
electronic equipment to malfunction.
Features
• Adjustable relative humidity range
• High switching capacity
• Long service life (>100,000 cycles)
• Maximum permissible air velocity of 50 ft./sec. (15 m/s)
• Maximum switching voltage = 250 VAC
250 V should be switched only in a non-condensing
environment
• Change-over contact
• Mounting clip for 35-mm DIN rail
• Connection: 3-pole terminal for AWG 14 max. (2.5-mm squared)
• Contact resistance less than 10 mΩ
