  • How Do Thermostat Controllers Work?

    11th Sep 2024

    Thermostat controllers are essential devices that regulate temperature in various environments. They ensure that heating or cooling systems maintain the desired temperature.  This article explains how thermostats work and what thermostats are used for, providing a clear understanding of their operation and importance. The Working Principle of Thermostat Controllers Thermostat controllers function by sensing the temperature in a specific area and adjusting the heating or cooling system accordingly. Here’s how the process works: Temperature Sensing Thermostats contain temperature-sensitive components, such as bimetallic strips or thermistors. These components detect changes in temperature and send signals to the thermostat control panel. Comparison to Setpoint Thermostats compare the current temperature to the desired setpoint, which is the temperature you want to maintain in the environment. If the temperature deviates from the setpoint, the thermostat takes corrective action. Activation of HVAC System Once the thermostat identifies that the temperature has strayed from the setpoint, it activates the heating or cooling system. This could involve turning on a furnace, air conditioner, or other HVAC equipment to adjust the temperature. Maintaining Temperature Thermostats continue to monitor the temperature and adjust the system until the setpoint is reached. Once the desired temperature is restored, the thermostat signals the system to stop, preventing overheating or overcooling. For example, Tosunlux’s SRT1150J thermostat offers accurate and reliable temperature control for various applications, ensuring consistent performance. Types of Thermostats and Their Functions What are the types of thermostats? The most common types of thermostats are mechanical, digital, and smart thermostats.

  • How to Choose a DC Circuit Breaker?

    19th Aug 2024

    No matter which DC powered system you are outfitting, properly selecting and installing circuit breakers is crucial for safety and long-term reliability. But with so many breaker types, sizes, and tricks to the trade, how do you make the right choice? Let’s break down the key factors. Key Considerations There are a few major things to evaluate when choosing DC breakers:  Voltage Rating DC breakers are rated for specific voltage ranges, so this must exactly match your system voltage. 12V automotive circuits use 12V or 12-32V breakers. Marine tinned copper wire needs higher 32V or 50V ratings. Overvolting a circuit breaker for DC voltage risks failure or fire. Always stay within the voltage window marked on the breaker. Current Rating This reflects the maximum continuous load the breaker can safely handle indefinitely. It’s listed as amps (A) and must exceed the total draw of everything downstream on that circuit. Include start-up surge loads from motors too. Unsure of the draw? Rate for 125% of wire capacity as a safety factor. Interrupting Capacity Shown as “iC” or “IC”, this is the breaker’s short-circuit withstanding limit in kA (thousands of amps). Higher iC handles severe power surges safely without welding contacts. Use iC matching or exceeding the circuit’s maximum short-circuit current if possible. This protects wiring in failure modes. Breaker Quality Cheap breakers can fail to trip under load or arc weld shut. Stick with top brand names like Blue Sea Systems, Reliance or Westmarine for durability. Consider ones with sealed covers and vibration resistance for marine […]
