Digital thermostat plug 15 A 1800 W

This plug-in controller switches heating or cooling loads up to 15 A at 120 V, delivering a maximum of 1800 W. A VA display shows the set point and current temperature with self-illuminating digits. The unit measures 1.53 in x 2.26 in x 4.14 in and operates on a 12 V supply. It is supplied as a 12-pack roll.

Greenhouse, incubator and homebrew users

Growers, reptile keepers and brewers who need automatic temperature maintenance between -40 and 210 with 0.1 precision will benefit from the four timing modes and power-memory recovery. Installers requiring a hard-wired panel-mount controller or a higher current rating than 15 A should look at alternative designs.

15 A relay contact rating

The single-pole relay is rated 15 A at 125 V, limiting the connected load to 1800 W. Any heater, chiller or compressor drawing more than this value cannot be controlled directly by this device.

Questions about this item

Should I pick the 120 V 10 A 1200 W version or the 125 V 15 A 1800 W version?

The controller you are viewing is the 125 V 15 A model rated for 1800 W, so choose this one when your heater draws up to 1800 watts on a 125 V circuit.

What does the 1800 W rating mean when I plug in a heater?

It means the relay can safely switch a resistive heating load of up to 1800 watts at 125 V without overheating or tripping the internal protection.

What does the 125 V 15 A rating cap in practice?

It caps the maximum connected load at 15 amps or 1800 watts on a 125 V AC supply; exceeding either value risks relay damage or nuisance tripping.
