Hi:
I am testing a circuit that measures the voltage generated by a high voltage converter.
An off the shelf converter (EMCO) generates 1500 volts that are delivered to a load. A voltage divider divides this voltage by 10,000 and an isolation amplifier (AMC1100) is used to transfer the value...
Hi:
I have a setup were I run a electromagnet with a PWM signal using 20 volts, usually at low dutycyles < 20%. PWM frequency in the low kHz range.
Around this electromagnet I have various sensors, cirucits etc.All of this (electromagnet and circuits) is inside a metal chamber (faraday Cage)...
Hi:
I need to alter the polarity of a high voltage source connected to a load at around 1 hz.
I have a high voltage (2.5 kv) power supply that has positive and negative outputs that can be floated to any ground reference. I basically need a high voltage H-bridge. Current is minimal, in the...
its 2500 Volts Dc currents in the micro and nano amperes range, accuracy, as best as possible, possibly in the microamperes scale. I found a isolation amplifier capable of isolating 2500V (AD210BN) I will give it a try and post the results...
Sorry, I think I used the term optocoupler wrong, what I want to do is measure small currents at high voltages. So I am using a isolation amplifier, that works on the same principle as the optocoupler.
If thereare no high voltage spikes, and it will be constant DC, would there be any problem...
Hi:
I am working on a high voltage application where current optocouplers do not meet the desired isolation voltage.
If I use a pair of optocouplers, the output of one connected to the input of the other (taking into account, minimum current requirements of input stage, and using a floating...
