Description

The SY9003 generates the low-level voltage and current signals used by the power amplifiers in a three-phase energy meter test bench. Its controller adjusts signal amplitude, frequency and phase in response to commands from the front-panel keyboard or a connected PC.

The unit also coordinates switching commands and communication with the bench’s error-processing system. Its front panel combines a display, keypad and status indicators for bench operation. A front-panel selector supports keyboard or computer operation, while the indicator lights report the power amplifiers’ protection status.

Configuration notes

Select the signal source according to the bench model, serial number and installed configuration. The SY9003 is identified as the three-phase model in the SONGYANG parts manual; it should not be assumed interchangeable with the single-phase SY9001.
