In the daily operation of industrial heating equipment, almost every field engineer has encountered this scenario: the moment the start button is pressed, the circuit breaker in the power distribution cabinet trips immediately—the equipment "goes on strike" before it even begins to work. This happens frequently, especially when the equipment is starting from a cold state: the ammeter needle swings violently to the maximum, a dull "hum" might be heard from the contactor, and then everything goes dead. Faced with this predicament, many people’s first reaction is to suspect the circuit breaker is undersized, complain about unstable grid voltage, or blame the power regulator itself. However, seasoned veterans will tell you that the real culprit behind these frequent trips often lies in the massive inrush current that occurs the moment startup begins. To understand this phenomenon, one must look at the physical properties of electric heating elements. Whether it is common resist...

When selecting a three-phase power regulator, many customers focus first on total power—asking, "What size do I need?" based on the equipment's actual load wattage. While this approach isn't wrong, power rating alone isn't enough; we also need to consider voltage, current per phase, load type, the temperature controller's output signal, and the electrical cabinet's heat dissipation conditions. First, distinguish between single-phase and three-phase systems. Use a single-phase power regulator for 220V single-phase heating elements, but for 380V three-phase heating equipment—such as ovens, electric furnaces, heat treatment furnaces, or drying equipment—we must use a three-phase power regulator. Even if the total power is low, if the load is wired in a three-phase configuration, we cannot simply choose a single-phase unit for convenience; you must calculate the current based on three-phase requirements. The key factor is the current per phase. For instance, with a 380V, ...

Ramp and soak controller are heavily used in Kiln industry for various application such as Heat Treatment industrial,Ceramics and Sintering industrial,Glass Manufacturing and Tempering,Chemical and Pharmaceutical Reactors,Semiconductor and Electronics Manufacturing, food processing etc. a perfect controlled ramp up and soak segments is crucial for these process. the process always starts out from ambinent temperature let's say 25 degree, for example , if you have a process like below:From Ambient temperature to set point 200 degree within 20 minutesAnd after temperature reach to 200 degree, the temperature will be held at 200 degree for 60 minutesIn field application, the tempeature can be somewhere high or low than 200 degree when 20 minutes elapsed. when this happens, the controller should not proceed to the soak segment cause the process value is way off the target value 200 degree, to solve this problem , our controller has a Wait function,  the temperature will go up fro...

Head-mount temperature transmitter is a device installed directly in the connection head of a temperature sensors, temperature sensor typically will be thermocouple or RTDs, the key feature of temperature transmitter is to convert small and raw signal from the sensor into analog signal like 4-20mA, the transmitter has various options such as isolated type,  Hart version,  Modbus RS-485 compatible version, below is an image on how it looks like and the way it is installed inside the connection head In many applications, the master device which receive the temperature signal often located at central control room or far away from the filed where the sensor installed, if the extension cable had been used, the signal will be affected by electrial noise and signal will suffer significant attenuation over long cable runs, therefore , by converting the weak signal into 4-20mA or other digital signal will minimizes the negative effects and saves cost too. as the extension cable is muc...

How to choose proper SCR power regulator according to your application ? SCR power regulator is heavily used in industrial application particularly heating application, to choose proper SCR, several key factors needs to be take into consideration.  1)first thing first, figure out your source whether it is single phase or three phase, the single phase SCR is for single phase source, 3 phase SCR is for 3 phase source, like 3 phase 4 wires, 3 phase 3 wires etc. if the load is single phase, the process is quite simple, make sure you select a SCR with the current rating 2 times higher of the actual load. for example, if you have a heater with 20 amps and 240Vac load, the proper SCR would be 40 amps and 240~480Vac load2)PIDMaxwell SCR power regulator only works for resistive load, make sure your load is resistive load like a heater, electric heater, infrared heater etc3)Identify your source, the source would be 3 phase 380V 4 wires source, like in China, or 3 phase 4 wire 400V in german...

ARAMP and Soak PID Controller is a specialized feedback control system designed to manage processes that require gradual changes (ramps) in a setpoint followed by stabilization periods (soaking). Unlike standard PID controllers that maintain a fixed setpoint, this controller dynamically adjusts the setpoint according to a predefined profile, ensuring smooth transitions between phases. Common in industries such as thermal processing, chemical manufacturing, and ceramics, it prevents system stress and improves process stability. Our MPU90 Series ramp and soak controller is a perfect choice. It has 0–25% FS accuracy and comes with PC software that records process values, setup values, and alarm events.   Key Features of a Good Ramp and Soak PID Controller: Accurate Setpoint Tracking: Accurately follows programmed ramp rates and soak durations, minimizing deviations even during dynamic changes. Smooth Transitions:Seamless changes between ramp and soak phases without abrupt outpu...
