Ebac Humidistat (Type HG, Gold Contacts)

The Ebac Humidistat (Type HG, Gold Contacts) is a mechanical room humidistat used as an on/off controller for relative humidity. It uses a Galltec Polyga measuring element and a gold-plated, voltage-free changeover contact, which makes it ideal for switching the low-current control circuits of Ebac desiccant and commercial dehumidifiers.

FAQ

Q: Why gold contacts?
A: The gold-plated, voltage-free contact reliably switches low-current control circuits, which is why it is specified for Ebac's desiccant and commercial dehumidifiers.

Q: What humidity range does it cover?
A: A scale range of 30 to 100% RH with an operating range of 35 to 95% RH.

Q: Which units is it compatible with?
A: Ebac DD200, DD300, DD400, DD700, DD900, and DD1200 desiccant dehumidifiers, plus the CD200, HGR1500, and Free Star.

Q: What is the contact rating?
A: A changeover (SPDT) gold contact rated 1 x max. 100 mA at max. 48 VAC.

Q: Can it control a humidifier too?
A: Yes. It works as an on/off controller for both humidifiers and dehumidifiers.
