Multipurpose
microprocessor electric power meters "Mercury –
230"
 |
Electric
power meters are designed for commercial registration
of active electric power in single-phase alternating
current circuits operating either in stand-alone
or as a part of automated power registration system.
Power
meters “Mercury-230” provide:
- accuracy
class 0,5S and 1,0S
- active-reactive
electric power and duty calculation in two directions
- registration
in multirate mode
- maximum
load power registration at given time limit
- registration
and storage of calculated data in nonvolatile memory
- calculation
results transmitting through digital and impulse
interfaces
- electric
power quality calculation (phase currents, voltages,
phase and frequency factors, sinusoidal current
and voltage distortion factors)
- data
displaying on LCD display |
