Thanks for the suggestion, but it must be my ambiguous question - in the Schneider Electric iEM31xx / 32xx series Energy Meters User manual DOCA0005EN-02 06/2013 there is no wiring for measuring DC Energy, only 3PH4W, 1PH2W L-N, 1PH2W L-L, 1PH3W L-L-N and 3PH3W.
My client asked me for a meter which could measure electrical energy on UPS DC side, so he can compare it with a measurements on AC side and calculate an efficiency of it.
sorry, for me i thought you mean the Opposite of not Direct (With CT).
Have a nice weekend
They might check with the UPS vendor as well, it's possible you can read the DC output register via coms?
We had to use DC Shunts to get a mV output. One of our SIs developed a Modbus card which gives the DC Voltage and Current inputs.
I suppose it must be a some kind of Hall effect IC sensor, as transformer is suitable for AC current only.
You can look at a special product from Veris Industries, also wholly-owned subsidiary of Schneider Electric, to monitor solar PV installation at the DC output from individual solar panels,
The only drawback I think would be that it starts with 8 channels, but if you require multiple channel monitoring, it can freely scale in units of 8 up to 32 channels.
