Voltage
Display of the actual mains voltage in volt (V).
Flicker
Display of voltage drops of the supply voltage over a configured period of time (number of half-waves, minimum
1 half-wave) for each PDU as time value / time. Always the last appearance of a voltage drop will be displayed.
Swell
Display of voltage overshoots of the supply voltage over a configured period of time (number of half-waves) for
each PDU as time value / time. Always the last appearance of a voltage drop will be displayed.
Peak
The MultiSensor-RACK measures the supply voltage with a sampling rate of 4000 measurements / second (250
µs per measure). A peak is the highest value per second.
Overshoots of the line voltages configured tolerance range in volt with the time of the appearance are displayed
in the table (last appearance of a peak).
Current
Display of the actual power demand of the connected power consumers in ampere (A).
Frequency
Actual mains frequency in hertz (Hz).
The frequency determines the length of the half-waves (50 Hz ≙ 10 ms, 60 Hz ≙ 8,33 ms).
Active power
The active power (P) shows the actual power of the PDU. Its calculated by multiplying voltage, current and the
power factor.
Apparent power
Total power of the PDU in volt ampere (VA). It results from the idle power and the active power.
Power factor
The power factor is the ratio between active power and apparent power. It indicates which part of the apparent
power is converted to the desired active power.
Energy consumption
Total energy consumption in kilowatt hours (kWh) since the start of the measurement. The consumption values
are stored in the MultiSensor-RACK and preserved even after a restart.
It can be reset in the configurations menu in the EnergySensor section.
Energy costs
Shows the actual costs for the energy consumption since the start of the measurement. The costs result from
the consumption and the configured price.
IMPORTANT!
To display the costs a price has to be entered in the configuration (section EnergySensor).
Output 1/2
Shows the actual state of the outputs for the PDUs power supplement of the end devices.
Reset alarms
Resets the display of Flicker-, Swell- and Peak-Alarms.
NOTE!
For actualization of the alarms Flicker, Swell and Peak a Retrigger time is configured which also avoids that
alarms are reported multiple times.
For the actualization / signalization of new alarms resetting the last alarms is not necessary.
