Hi team,
Here's an issue from the customer may need your help:
Open-loop test is performed as required and the data is as follows which is different from the manual given:
The customer would like to know what's the possible reason for that. Could you help check this case? Thanks.
Best Regards,
Cherry
Hi Chen,
Thanks for your help.
I know it is under build 1, but at which step(in the manual) does customer see this?
The open-loop test is performed as follows: as per the manual, the input is HV=120Vrms L-N,60HZ,Vbus=320V, and the output value is 270V, as measured by CCS. However, the three-phase voltage monitoring is good, with three-phase current being half of the manual.
At the above step, when HV = 120Vrms L-N,60HZ, it was found that CCS had only acquired a Vbus of 270v, three phase AC current Irms = 0.46 which is inconsistent from the manual given(Vbus = 320V, Irms=0.92).
Thanks and regards,
Cherry
