"Monitor" alphanumeric display
9.5 Measurement system
Single-unit or modular UPS
Frequency converter
The "Monitor" system displays a number of input and output measurements at different points in the system.
– Mains 1
– phase-to-phase voltages,
– currents of the three phases,
– frequency;
– Mains 2
– phase-to-neutral voltage,
– phase-to-phase voltages,
– frequency;
– battery
– voltage,
– charge or discharge current,
– remaining battery time (calculated for each UPS);
– inverter output
– phase-to-neutral voltage,
– phase-to-phase voltages,
– currents of the three phases,
– frequency,
– active and apparent power,
– ratio peak current / rated current rms;
– total load
– phase-to-neutral voltage,
– phase-to-phase voltages,
– currents of the three phases,
– frequency,
– active and apparent power;
– option
– battery temperature.
Note:
Frequency converters without batteries are not concerned by the battery measurements. The displayed battery voltage
corresponds to the DC voltage at the RC output.
