The design concept of Model VR-2746 ACV card was based on
Microprocessor. It uses 12 bit A/D to design its voltage module cards
for voltage measurement of RTU. Its back side of communication
port is using the protocol of RTU Local I/O, while the frond RS-232
communication port is for maintenance only. And this RS-232 port is
easy accessed and programmed by PC Tool to setup the parameters
and records.
The ACV Card Features:
 4 sets AC voltage input : 0-300V
 Each sampling cycle : 32 points
 True RMS converter
 Accuracy : ≦ 0.5% fs
 Field programmable PT ratio
 Instant maximum and minimum logger
 Event record : 32 events
 Data updating interval : 1 second
 Communication port : RS-485 + RS-232
 Completely modulated and plug-in type cards which is easy to
