SY9013 Power Amplifier
A PWM power amplifier used in the voltage and current source system of configured SONGYANG energy meter test benches.
Description
The SY9013 power amplifier forms part of the test bench’s voltage and current source system. It uses pulse-width modulation to amplify the signals supplied by the bench signal source. The module works with the signal source and the associated switching assembly as part of a coordinated source system.
The SONGYANG parts manual describes protection for voltage short-circuit and current open-circuit conditions, together with current limiting. The photographed module has separate voltage and current amplifier indicators and a front cooling fan.
Configuration notes
Amplifier selection depends on the bench model, serial number, installed source arrangement and required output configuration. Confirm the supply, connectors and wiring against the existing assembly before selecting a replacement. Contact us with photographs of the model label and connections so that the appropriate configuration can be identified.
