Product description:

I. overview

YWH-CRH humidity controller is a proportional control function of the controller (contact output). Can be set according to user requirements, the lower limit of humidity control points, and relay output. The utility model is an economical and practical humidity control device.

Two, product features:

1 France HUMIREL HM1500 humidity sensor. 2 high reliability and long term stability. 3 high resistance to chemicals.

Three, model:

YWH-CRH

Four, technical indicators:

Humidity control precision of 10~95%RH control ± 3%RH user specified minimum humidity humidity limit user specified control limit return difference: 5%RH: 5%RH (lower limit can be set according to user requirements) relay contact capacity is AC:220V (380) 7A response time < 5S auxiliary power supply P1:DC24V± 15% P2:DC12V± 10% 1W < the power surge voltage 5kV/1.2 ~ 50μ s working environment temperature: -30 to 60 DEG C, humidity: 10 ~ 95%RH configuration 72mm× 37mm&times 200g 112mm; the weight of the product

Five, the use of instructions
