Digital Voltage Meter voltmeter


Digital Voltage Meter voltmeter


Main Features:
Equipped with alternative voltage and alternative current signal inputs isolated by transformer. It provides the functions of communication, retransmission and alarm. The main board is isolated with heavy current.
Measurement accuracy is 0.2%FS.
Provide dual display instrument.
Up to four channels of alarm, including two high limit alarms and two low limit alarms, Introduce digital calibration technology, easy to operate and maintenance free, automatically adapted to 50Hz/60Hz power measurement.
Support RS485 and RS232C communication interface and AIBUS communication protocol, which is 3 to 5 times faster than other field protocols.
Provide signal retransmission functions with transmission accuracy of 0.2%F.S. able to output standard industrial signal.
Universal power supply of 100-240VAC or 24VDC and various installation dimensions for users to choose from.
High quality and latest hardware design using high performance electronic components energy efficient less temperature drifting provides higher stability and reliability.
ISO9001 and CE certified, achieving world class level of quality, anti-interferenceability and safety.
