Power measuring watt meters are a necessity with today's energy saving awareness.  Using the PA110 several electrical measurements can be taken during testing - from just one set of connections. These instruments are important when accurate watts measurement is required for appliance testing, certification and traceability. In addition to power measurement (real power), reactive power (VAr), apparent power (VA), voltage Vrms, current Arms and power factor can be viewed with ease. The PA110 watt meter simply connects between the ac supply and the load, various current transformer and shunt options allow measurement with any size of current. Typical watt meter applications include appliances like lamps, microwave ovens, electric stoves, heating, air conditioning, TVs, monitors, computers, electronic lighting and motor controllers. Powertek wattmeters are equipped with safety terminals (4mm/banana) along with optional "breakout" boxes and clamp probes for fast and safe measurement.

Starting inrush current 5A-65A (peak)

Digital transmissions protected by infrared communication interface

Ac or battery powered

Numerous functions: current range switching, HOLD, filtering, starting current, etc.

Excellent readability: 3 measurements displayed simultaneously with a digit height of 14 mm

The PA120 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 PA 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 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 the PA110/120 wattmeters, is the RS232/USB interface based on infrared isolation. The link is established using a magnetized optical head 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.
