The SPCPro2 and its dedicated PC software package ‘PowerPackPro’ combine new
technology and years of experience into an unbeatable low-cost package.
It is the latest development of the well-proven “3 currents, 1 voltage” design, which
allows accurate 3 phase power and energy measurements to be made safely. The unit
uses 3 off flex type CTs (current transformers) for current measurement, and a standard
wall socket plug for voltage measurement and power supply. Set up and download of
the SPCPro2 is via a USB connection to any PC running Windows XP or later software,
and all survey data and user settings are securely saved in non-volatile ‘flash’ memory.
The instrument uses a sophisticated auto-ranging measurement technique which
ensures that excellent accuracy is maintained from 2 amps to 2000 amps without the
need for any user-setting of range, or swapping of CTs. It has been developed with ease-
of-use as a No 1 priority and is therefore simple to set up, connect and download,
assuring even non-technical or inexperienced users of correct results from day one.
The SPCPro2 is a professional-grade instrument for the measurement and
logging of three-phase and single phase electrical loads. It is able to measure the
following parameters:
Voltage amplitude x 1
Current amplitude x 3
Current phase angle* x 3
*Referenced to the measured voltage
From the above data, the following parameters are presented via the
instrument’s dedicated software package ‘PowerPackPro’.
Voltage (1 phase)
Current (3 phases)
Power Factor (3 phase average)
kW (active power (3 phase total)
kWh (active energy) (3 phase total)
kVArh (reactive energy) (3 phase total)

The unit is fully self-contained and is supplied with a set flex-type CTs, plus
voltage connection and PC connection (USB) cables. The rechargeable battery
provides on-board power for surveys of up to 2 weeks duration where mains
power is not available.
