Features:

• Size: active power
• Calculation: fixed average, over the selected period
• Integration time: 5/8/10/15/20/30/60 min
• Counting hours and minutes
• Counting start: selectable, voltage presence opp. power
• Voltage: phase voltage > 20V
• Power: three-phase active rated power programmable value: 0.1...50%Pn
• Pn = Rated three-phase active power = Rated three-phase voltage Un x Current In x 3
• Un = 400V
• In = 1A or 5A
• Pn = 400V x 5A x ?3 = 3464W opp. 400V x 1A x ?3 = 692.8W
