1. General Information
PMAC735 is a multi-functional power meter, integrating data acquisition and control into a whole.
It can take the place of numerous meters, relays, transducers, and other components. Besides, it
can be used in electric power systems of various voltage classes.
PMAC735 provides one RS485 communication port, so it can be integrated into any electric
power monitoring system. The management software or other configuration software with which
it is equipped enables the setting to be carried out easily. Furthermore, it provides an optional
PROFIBUS communication port, whose 1.5 M communication speed can fully meet the demand
for obtaining real-time data on the site.
PMAC735 is really a measuring meter based on true effective values, able to carry out accurate
measurement of highly non-linear loads. The complicated sampling technology enables it to
measure true effective values up to the 31st harmonic. The user can read remotely some dozens of
measured values and minimum/maximum values on a display screen or via software.
PMAC735 provides multiple extension modules and advanced software functions to meet the
demands of different sites. Its flexible DI/DO configuration facilitates the design of the user.
PMAC735 adopts connection realized by terminals that can be pulled out and inserted, thus
facilitating on-site wiring and maintenance. Especially for the parts to which current is inputted,
PMAC735 uses lockable fixation connections to prevent dangers that may be caused by
accidental coming off of connections.
