Features & Benefits

The 2020A Series is the latest development from Measurements International. They represent a new proprietary sampling method for the precise measurement of electrical power for applications including R&D, product efficiency testing, transformer testing and other power conversion products. Developed as a power analyzer in a self-contained standard or in a transformer loss measurement system.

The single phase version Model 2020A is offered in the standard wattmeter version or can be purchased as the 2020A-XP extended performance for full power analyzer applications.  It features total harmonic distortion analysis, complete waveform analysis and phasor analytical representation.

A large touch screen display is used to change the input parameters and for indicating the voltage, current and power measurements simultaneously. Waveforms of the input voltage and current can also be displayed and saved to a USB Stick on the front panel or transferred to a computer over the LAN. An Rs232 interface is standard and an Optional IEEE-GPIB card is available. With the IEEE Card only the Voltage, Current and Power values can be transferred. Waveform data is transferred over the LAN.

The 2020A can be used to measure line to ground and line to line voltage measurements that are 120° apart with one current input. The current input is a two-stage-compensated current-transformer with 10 current ranges from 5A down to 5 mA, the voltage input consists of an accurate voltage divider with 120V and 240V ranges.

The displayed output for power is expressed as VI Cosɸ. The measurement high accuracy’s is maintained for all power factors. The relative conversion error of the output is linear and does not depend on the magnitude or distortion of the input signals.
