Main features
Measurements
  • Three-phase 3-wire or 4-wire unbalanced load operation, bi-phase and single-phase.
  • Direct measurement up to 600 (750) VAC.
  • Programmable 1A / 5A current full scale.
  • Fully bi-directional, four-quadrant readings. 10 energy counters are available, the apparent power/energy is splitted in four counters: import lagging, import leading, export lagging, export leading.
  • Volts, Amps, Power, PF, Frequency, Energy, Min/Max values, Demand, Harmonics, etc. The full version instrument provides more than 600 measured/calculated parameters and shows on the LCD more than 30 graphical pages.

Power quality
  • Individual & total harmonic distortion for voltage and current up to the 50th order. The harmonic content is represented like even, odd and total.
  • CPU2 option: the co-processor board perfoms the simultaneous high-resolution sampling of voltage and current, allowing the cycle-by-cycle power analysis for 50/60 Hz lines. The CPU2 board supports different application like VMAX and WCAP (see below). The instrument with CPU2 board performs at the same time the wattmeter functions, the harmonic analysis, the basic recording function and the selected cycle-by-cycle power analysis function.
  • VMAX option - two functions are selectable:
    1. Sags & swells detection on L-N voltages with half cycle resolution (10ms @ 50Hz). Pre- and post-trigger logging (100+100 half cycles RMS values). The detected events are recorded. This data is viewed on the PC according EN 50160 standard.
    2. Min/Avg/Max values calculation and recording with one cycle resolution (20ms @ 50Hz). This function allows to record up to 10 parameters selected among voltage, current, power, PF and frequency. The data is viewed on the PC according EN 50160 standard.
  • WCAP option - advanced waveform capture function of currents and L-N voltages. In case of single trigger the threshold mode is programmable as voltage or current; in dual trigger the threshold mode is xed including both parameters (voltage&current), allowing the waveform capture in case of threshold overcoming both for voltage and current. The instrument can store up to 10 + 200 waveforms before and after a threshold overcome, with a resolution from 8 to 32 samples (depending on the number of waveforms). The WCAP option includes a second selectable function: Min/Avg/Max values calculation and recording (see previous paragraph).

Recordings
  • 2 MB non-volatile memory for data storage.
  • Up to 10 programmable recordings with different start and stop time. Different type of recordings can be chosen:
    • import/export active, reactive and apparent power demand with programmable average time.
    • instantaneous read values selected between the main parameters. The recording interval time is programmable between 1 and 9999 seconds.
    • instantaneous min/max values measured during the recording interval time. The recording interval time is programmable between 1 and 9999 minutes.
    • voltage and current harmonic values measured during the recording interval time. The recording interval time is programmable from 1 to 60 minutes.
  • Time-of-Use (TOU) programmable data recording. The TOU function stores the energy consumption in different registers according the programmed time-scheme. A group of 120 registers give the situation of the previous and present day, and of the previous and present month. This feature is designed to t different tariff structures. It is possible to program up to 10 daily tariff schedules containing up to 3 tariffs and 8 tariff changes. Each schedule can be assigned to the days of the week and months as requested. Up to 20 holidays can be assigned to the lowest tariff. A diagnostic algorithm checks and noti es any setup overlapping.
  • Event, alarm and digital outputs ON/OFF recording. The instrument records the status change of 8 programmable set points, the digital outputs ON/OFF and the instrument supply ON/OFF. All the events are integrated by date and time reference.
  • The CPU2 option includes 1 MB non-volatile data memory. Depending on the CPU2 con guration the following information (already described in the “Power quality” paragraph) can be recorded:
    • sagsandswellsevents.Theoccurringdipsandovervoltageoveraprogrammablethresholdaredetectedandtheinstrument records the date and time of the event, the lenght and the RMS value of 100+100 half-cycles before and after the event.
    • min/avg/max values of the main measured parameters with continuous sampling and 1 cycle minimum resolution for RMS calculation. The resolution is programmable between 1 and 99 cycles to simulate the recorder response time as needed. The programmable average time de nes the time interval between recordings.
    • more than 200 waveforms when a programmable threshold is overcome. The instrument records up to 10 + 200 waves before and after the trigger, with the time reference. The resolution is programmable from 8 to 32 samples / cycle.

Modularity
  • Four slots for optional AO plug-in boards (up to no. 2 analog outputs 0-20 or 4-20 mA).

Communication
  • Both RS232 and RS485 selectable by dip-switches.
  • MODBUS or A2 ASCII protocol.
