SoliStat™ 2-20 Thermostat for DC: Max. 20 Amps, 24V

The SoliStat 2 is a user-friendly, long-lasting thermostat for DC-powered heating and cooling applications. SoliStat is an all-in-one, ready-to-use temperature controller, incorporating a calibrated RTD sensor, a microcontroller, and a solid-state switching mechanism, all inside a rugged, weatherproof housing.

Model 2-20 Specific Features

• Temperature measured through a metal heatsink on the housing via an RTD sensor
• Two-wire output
• Maximum current of 20 amps
• Example applications: Long-run heat tracing on pipes; high-amperage enclosure heaters

SoliStat's advantages

No Arcing: Because of its solid-state construction, SoliStat exhibits none of the arcing and consequent corrosion associated with the opening and closing of mechanical thermostats.
Solid-State Reliability: The combination of RTD temperature sensing, solid-state switching, and weather-resistant construction ensures reliable and repeatable operation over the course of the SoliStat's life.
Wide Range of Setpoints and Configurations: SoliStat models are available with maximum currents up to 30A, for heating-only or heat-cool (dual-channel) control, with internal or external temperature sensing, and with or without low-voltage power-saving (shutoff) mode. Check the SoliStat product family page to see all the models available.

Applications

The SoliStat has been developed for DC-powered applications that require simple on/off control in response to changing temperatures, such as:

• Off-grid industrial uses:
  • Engine component temperature regulation
  • Freeze prevention in water lines and filters, using heat trace cable
  • Equipment cabinet warming
• Transportation:
  • Fuel line and fuel filter warming
  • Operator comfort heating and cooling
• Hazardous areas
