Thermostatic Heater

Low surface temperature
Integrated thermostat
Compact size
Wide voltage range
Double insulated protection
DIN rail mountable


The ALHTR150G-P is a touch-safe heater for use in enclosures. This heater’s unique design utilizes natural convection which results in a circulating current of warm air. The surface temperatures on the accessible side surfaces of the housing are minimized as a result of the heater design.

Heater can be installed at an additional charge.
