I need to measure the frequency of a DC line that is 575 volts. The power is controlled variably with an scr fired controller. Sorry for the confusion with this application
Skogsgurra Yes not enough information.I am looking to measure frequency on an induction melting power supply it is a variable frequency and runs at 575 vdc the frequency varies between 2khz and 3khz I would like a analog signal 0-10vdc so that I can monitor the frequency. Thanks for any help...
I have an application that I need to measure a 0-600vdc line with a frequency range from 2khz-3khz and need an analog output of either 0-10v or 4-20ma.Any ideas where to find this
I have a electrolytic cell with a silver nitrate solution and was wondering if I could replace my existing fiberglass tank with stainless steel tank or if this would cause any problems with the tank or the electrolytic process
I am looking for the test standards for an contactor AC-4 test I know the make and break current is 6 times rated load but am interested in what timing this standard requires for on and off time
Thanks
Hi
I am working on a project where I have a room of about 1000 cubic feet in this room I have an electrical load of 645 kw with a 10% duty cycle I am not sure of the temperature generated by this load but I would like to keep the room at no more than 150 F using intake and exhaust fans from...
I am trying to measure a current of about 550 amps 60 Hz in a 3 phase circuit this signal input to an automation controller.The load is only on for 1 sec and during this time I need to determine what the sequence of phase operation is and what the load is.The other information I am looking for...
It is 60 Hz what is the response time of a regular CT as the output from that would be input into the controller which has a 75 ms response time using a 0-5 a signal if I can get a 0-5 vdc signal my controller response time is at 10 ms but I am sure I will lose with a conversion but not sure how...
Hi
I am looking for a current sensing device with a response time of 100 ms or less that will be able to sense up to 600 amps this will be interfacing with an automation controller.Any input will be helpful
Thanks
Hi
I am looking for an inexpensive way to stain copper and brass for an in process operation that would be rolled down in a future process but able to keep the staining for later inpection. Thanks for any ideas
The welders are connected solidly by electrode rolls one on the top of the material and one on the bottom.
The DC welders are SCR controlled
The AC welder does have a firing circuit for frequency control
Thanks for any help
I have 3 pieces of equipment 1)2-DC electric seam welders
2)AC electric seam welder
These both operate at a very low voltage (5V) and high current (60 A 480V primary) using a high fequency firing circuit all welders have 1 side grounded.When operating the DC welders...
