EM6436
• Monitors active power & energy consumption, system voltage, load current and PF
• Displays Amps, Power, PF simultaneously
EM6400 All of the above plus:
• Optimizes demand utilization
• Analyzes power quality
• Helps energy balancing
Demand Parameters Option (EM6400)
• Monitors Demand – Present, Rising
& Maximum, Time remaining
• VA & W demand is selectable through
setup table
• Demand may be Sliding window (auto)
or Fixed window (User), selectable
through setup mode
• The time of occurrence for the Maximum
Demand is based on “On hrs” of the
system
• Maximum Demand can be cleared
independently or along with the
integrators through the CLR function in
the setup mode
