Introduction:
- The Lorentzzi® SSR-40LA is an affordable 40A 4-20 mA controllable solid-state regulator primarily used for controlling the power of heaters.
- As the control signal increases or decreases, the output voltage also increases or decreases accordingly, thereby increasing the heater’s power. Therefore, when used with our 4-20 mA output TCX5 PID temperature controller or PLC, it is ideal for controlling various types of heaters.
- To start the internal components, when using this product, ensure that the voltage applied to the controlled terminal is greater than 90VAC, and then you can adjust the output from 0% to 100%.
- Compared to our SSR-25LA product, the SSR-40LA solid-state voltage regulator can handle greater power, up to 4400W if the heating element is powered by 220VAC, and up to 2200W if powered by 110VAC.
- Since this SSR-40LA can control a maximum current of 40A, a suitable heatsink should be used, such as our W-70 screw-mount heat sink or D-74 DIN rail heat sink.
- Applications of this 40A solid-state voltage regulator include HVAC systems, packaging machinery, automatic sealing machines, electric hot water boilers, sauna rooms, coffee machines, and more.
