SoliStat™ DC Thermostats

The solution for endless thermostat burnouts in DC applications.

The SoliStat 2 is an easy-to-use, long-lasting, and weatherproof temperature-controlled switch for DC-powered heating and cooling applications. It can switch up to 30 amps of current and runs on supply voltages from 6 to 24 volts DC. Its calibrated RTD sensor, microcontroller, and solid-state switch, all incorporated in a rugged and weatherproof housing, make SoliStat the most reliable one-piece, ready-to-use solution available for DC temperature control applications. SoliStat products are offered with an unprecedented 5-year warranty.

SoliStat is the only one-piece, ready-to-use temperature control solution available for use in these situations:

• Direct current (up to 30A) is being switched
• Extreme operating temperatures: from −40°F (−40°C) to +257°F (+125°C)
• Operation is on voltages from 6 to 24 volts DC
• Accurate trip-point temperatures below 32°F are needed
• Low-power standby/shutdown mode is desired

SoliStat's advantages

No arcing means long-lasting
Because of its solid-state construction, SoliStat exhibits none of the arcing associated with the opening and closing of mechanical switches.

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
The standard configurations for SoliStat are:

• On/off control, factory-programmable lower and upper trip-points from −40°F to +257°F inclusive, ±1.0°F tolerance, minimum deadband of 3.0°F.
• Fixed on-time control, factory-programmable trip-point from −40°F to +257°F inclusive, factory-programmable on time in 1-second increments.

Electrical Flexibility, Ease of Customization
SoliStat is available in many configurations. The following are our standard models. Other configurations are possible; please contact us to learn more.

Applications

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

• Transportation:
  • Fuel line and fuel filter warming
  • Operator comfort heating and cooling
• Off-Grid Industrial uses:
  • Water line and filter freeze prevention with heat trace cable
  • Equipment cabinet warming
  • Instrumentation monitoring and temperature regulation
