Three phase power meters / watt meter are a necessity when several electrical measurements are to be recorded during testing, using just one set of input connections.  Typically, three phase power meters are important when accurate watts measurement is necessary for certification and traceability.  In addition to power measurement (watts), reactive power (VAr), apparent power (VA), voltage rms, current rms, power factor, can all be viewed with ease.  All Powertek power meter / wattmeters simply connect between the ac supply and the load, various current transformer and shunt options allow measurement with any level of current amplitude.   Typical three phase watt meter applications include appliance testing like generators, electric stoves, heating, air conditioning, pumps, fans, electronic lighting and motor controllers .  All our  power meters are equipped with safety terminals (4mm/banana) along with optional "breakout" boxes and clamp probes for fast and safe measurement.

The PX 120 is designed for use in colleges, universities, installation and industrial maintenance departments. It measures active and reactive power on single phase and three phase 3-wire balanced power systems.  Even though the PX wattmeters measure many ac parameters, they are simple to operate.  In addition to the main ac measurements, it has INRUSH functions for loads which draw large amounts of current at switch on and an averaging function, extremely useful with unstable measurement conditions.

It is has a clear 14mm high, 999-count display capacity (4 digits) on three lines, with simultaneous display of three values: voltage, current and active power or reactive and apparent power.
A special feature of this new wattmeter is its infrared transmission mode. The link is established using a magnetized optical head simply positioned on the front panel of the unit ensuring true electrical isolation of its interfaces.

"Wattcom" data processing software is available as an option for data transfer, display of the quantities and screen printouts.
