Remarks
|
|
1
|
Remotely acquiring alarm/digital signal
|
Transmit to the PCU the protection signals such as the AC overvoltage/ undervoltage, Phase failure, output overvoltage/undervoltage and rectifier overtemperature, and the fault signals of the rectifier.
|
|
|
2
|
Remotely acquiring analog signal
|
Measure the output voltage and current of the rectifier, and send them to the LED of rectifier for display and report to the PCU.
|
|
|
3
|
Remotely controling system state
|
Based on the commands of the PCU, control the on/off and boost/float charging of the rectifier.
|
The manual control is also furnished to shield the control of the PCU.
|
|
4
|
Remotely adjusting voltage analog signal
|
Based on the commands of the PCU, regulate the output voltage of the rectifier.
|
|
|
Based on the commands of the PCU, regulate the output current limiting threshold of the rectifier within the range of 10%~100%.
|
