The Chroma series 66200 power analysers are suitable for measuring a suite of parameters including true RMS voltages and current as well as their peak values; frequency; active, reactive and apparent power; power factor; total harmonic distortion of current and voltage; crest-factor for current; and energy.
The analysers are designed for use with domestic, IT and industrial devices and the 16-bit DSP input stage together with the maximum sampling speed of 240 kHz make them suitable for SMPS applications.
The use of an in-built LP filter permits the removal from measurement of high-frequency noise current which generally does not contribute to power consumption. Inrush current can be measured as triggered by setting a current level at which the measurement is to begin or through the use of an external TTL signal.
An energy averaging function using a user-defined integration period permits power measurements in instances of unstable power consumption by the device under test.
The analysers can be chosen to cover line currents to 20 A and voltages to 500. The analysers have a range of interface options including USB and GPIB ports, making them suitable for incorporation in ATE systems.
