Part Number: AMC1200EVM Other Parts Discussed in Thread: AMC1200 Hai, I like know Is it possible to use AMC1200EVM for measuring PV voltage and current.
Hi , Alexander,
I shall now continue with my tests. At the moment I don't see
further problems. So I think we can close the thread.
Best regards

Part Number: AMC1200EVM Other Parts Discussed in Thread: AMC1200 , Dear best partner,
I want to read the voltage level of the isolated circuit block-A by the CPU in the circuit block-B.
**X point voltage of the block-A is transmitted to the A/D which is …
Part Number: AMC1200 Tool/software: Hello team,
Customer found an abnormal issue of AMC1200 on MD system. Could you also help on this issue! Very thanks.
Failure Description:
1. When 220Vac On, VBUS voltage should normally show around 310Vdc, but this…
Hi Smith,
Actually i use AMC1200EVM board to test my current sensing circuit.
I connect the AMC1200EVM board J2 pin 1 to Rshunt point A and J2 pin 2 to Rshunt point B.
Rshunt value i use 116.mOhm. AMC1200EVM board VDD1 and VDD2 i supply by 2 external…
Hi Hans,
I went to the lab to test the AMC1200EVM and got the following results:
I shorted the inputs and used 5V power supplies. The math scope is the FFT on the positive output and the waveform view shows both the positive and negative outputs. Our…
Part Number: AMC1200EVM Other Parts Discussed in Thread: AMC1200 , TIPD104 Hi, I want to measure a current from a high voltage isolated power supply (3000 volts, with ground is different (isolated) from circuit ground), The current measurement ranges from…
Hi Ku,
Yes - VDD1 is not correctly designed.
" As GND1 will be connected to the high voltage line, 5V will not be derived for VDD1. You may need to consider designing a discrete isolated DC/DC converter such as what's present on the AMC1200EVM:…
Hi Walter,
How you have your schematic setup looks correct and the AMC1100 should be fine. You will essentially tie the high side ground, GND1 to the line and the isolated power supply will float +5V with respect to the line voltage. Keep in mind you…
Other Parts Discussed in Thread: AMC1200EVM , AMC1200 The AMC1200EVM board is working fine but one problem appears: the inputs from both amplifiers are not galvanic isolated from each other. The internal diodes made connection from VINP to VDD1 and from…
