MFR012 |
| Features |
| |
| Adjustable relative humidity |
| Change-over contact |
| High switching capacity |
| Easily accessible capacity |
| DIN rail mounted |
| |
| When the relative humidity in the power distribution box exceeds 65%, EFRO12 will control the heater heating, in order |
| to reduce the moisture condensation and effectively prevent corrosion. Compared with mechanical thermostat, EFRO12 |
| with low hysteresis, making it's switching point and setting accuracy more precise. |
