Measuring frequency F=1.5kHz

update !

Frequency of AC power supply=1.5kHz, measurement voltage U=380V, measurement current 1mA<I<300mA,
Require:
(1) Measurement accuracy 0.5%
(2) Current, voltage, power angle, phase, frequency, etc.

Please help recommend a suitable solution, thank you!

The ADE parts are really designed for a fundamental of 50 or 60hz. The measurement bandwidth covers your freq but some functions will not work properly. I would suggest and ADC and a Micro might be a better option but this will require code development.
