Hi All

Does anyone know of a manufacturer of a stable and accurate AC current source, operating at around 50Hz, 0 to 20mA.

Need something like this for calibrating some equipment.


Thanks in advance

Ref. Info:
Your specification looks twisted from Process Control Instrumentation view point.
0-20mA AC is not used (4-20 mA DC , Yes, yes).
Reading my catalog of test equipment:nothing
Frequency generating signal: yes.
I understand you need a variable (say 50 Hz)
current genertor. You might make you own using
variable transformer and panel meter.
The only problem here remains the accuracy of the AC ma meter (signal distorsion from the sine wave...)
