The current will be 2 amps or less and need to energize a panel lamp when the motor is running along with a future interlock to shut the system doen on a motor interruption. Will the CR 5395 do this

1 Replies and 2206 Views 603 series details  2206  1 Started by  Evran Zihnioglu I am interested in 603 series split core transformer. I have some questions about the product; 1. What is the difference between 603 and 603D. 2. In the datasheet, it is mentioned that the product can work 50-400Hz frequency range. I will use this transformer where maximum frequency could be 430Hz theoratically. So I am wondering that What will be the attenuation level above 400Hz. Could I use this product in the specified frequency 3. In the datasheet of the product, ...

1 Replies and 2524 Views DC Hall Effect Current Transducer frequency response  2524  1 Started by  Chris Penrose The product I am testing produces 24V switched (PWM) at 20kHz to supply 200A DC current into a 0.12ohm load in series with a 1mH inductor. The current is a 20kHz triangle wave. To calibrate this current I am currently using a 200A / 100mV shunt into a 6.5 digit DMM (mV). I would like to use the CR5210-300 however I am concerned about what it will do with the 20kHz component. (Ideally it will provide a accurate average current). Any ideas

1 Replies and 2494 Views Split Core Transducer Temperature Ratings  2494  1 Started by  Evran Zihnioglu What is the operating temperature limits of 603 and 610 series And also, because these transformers are split core, what is the mechanism to fix the core. I am planning to use them in a modest vibration so the one that has better mechanical integrity is the one that I looking for. Regards.

If it will work on 50 Hz, that would broaden your potential marketplace substantially.

What I want to know is that when you say supply is 24V - 10 it means that there is an isolation amplifier/voltage regulator between the supply circuit and and the transducer circuit, right I need to make sure about this, as I don't want noise in the transducer output,given that my supply can have around 1V spikes at times. Please clarify this, else I need to think of routing the supply thro...
