Hi to all. I'm trying to set one Rex-c100 pid controller on my kitchen oven.
Before buying the controller I believed that the power supply to the heating resistor would be proportional. Now that I have mounted it and I have tried different combinations but the output always remains on/off. My Fluke clamp meter always shows the same value (10amp). Is it right for it to be like this? I thought that as the temperature reaches the target the amps would decrease.

 

What's wrong with my question? Did I by any chance put it wrong? Thank you

 

Did you read the instructions? It looks like this PID controller has a time/duty proportional cycle over some time period. The REX-C100 is a PID controller with PWM output.

I confirm that this product is not able to moderate the consumption of the oven. Nonetheless, it keeps the temperature constant. All things being equal, it reduced cooking time by 30%. I'm still looking for a solution that will allow me to moderate my oven consumption. Please if you have any ideas tell me.

It does moderate the consumption of the oven by using PWM. The thermal lag smoothing effect between on/off cycling is the time based equivalent (but not as accurate) to AC current/power control regulation. You won't gain much by going to to AC phase-angle control if the temp control is good now.

Since consumption is measured by rate across time (kWh) the consumption is moderated, just the peak value remains the same.

 

the action of my own is only on and off. the consumption is 0 or 10amps. there's no pwm or thig like this

What does that mean? Sure, if it only stays off or on without ever switching again but that's not what the controller is doing if it's regulating to the setpoint.

If that is the case, how is it maintaining the set temperature? There must be some control action operating or the temperature would just rise to maximum (or more!),

Perhaps the PWM frequency is too high for your measurements to discern??

 

I'm not familiar with the nuances of clamp meters, but is the meter perhaps showing PEAK value rather than average? To show a pwm controlled value the average reading would be needed.
