The 63200E series are high power DC loads that include a choice of three operating voltages, 150V, 600V and 1,200V, with power levels from 2kW to 24kW and up to 2,000A in a single unit. Power levels can increase up to 240kW when multiple units are paralleled.

These high power loads are designed for testing a wide range of EV products including DC charging stations, car battery discharge, on board charger power components, and other power electronics components. With its high power capabilities, parallel control and dynamic synchronization functions make this load ideal for automotive batteries, fuel cells and more.

The 63200E load's master/slave control application enables units with the same voltage specification to be used in parallel and synchronized dynamically to meet the power testing requirements. In addition, a 255-set data storage function has been built-in for recall of the stored settings at any time. When used in automated testing, the save and recall functions can save a great deal of time.

Average Mode and Integration Mode for Power Measurement

When using a traditional power meter, unstable measurement data can occur if the UUT power consumption levels are unstable or operating in non-linear modes (i.e. power supply hiccup modes). This is due to load current conditions which maybe different for different measurement aperture windows (T1, T2, T3 and T4 below). A simple averaging calculation can only provide a visual stable value but still lose some transient data.

A Window Mode method that calculates all data within the user-defined window time (Tw) is recommended. So, users can get a real average value without any data lose. An accumulated energy approach method (i.e. integration mode) for power measurements is also provided. This integration mode calculates active power values by integrating energy from V and I in a user-defined time period (Ti). In this way, users can achieve accurate readings with guaranteed transient-free variations. The 66200 meters provide a 10 mA minimum current range with crest factor 4, and 0.1 mW measurement resolution for low power application (<10W), and less than 2% uncertainty even for No-Load mode power measurements. These functions make 66200 an ideal choice for ENERGY STAR / IEC 62301 / ErP measurement requirements.

THD Measurement and User Define Orders Distortion

The Model 66202 Digital Power Meter can measure voltage and current Total Harmonic Distortion (THD) directly which can be displayed in percentage format. For some requirements (ENERGY STAR), users need to verify the THD of AC supply voltage when supplying the UUT in the specified mode not to exceed 2%, up to and including the 13th harmonic (as specified in IEC 62301). The Model 66202 also provides a function to define a user-specify distortion order n, (n is from 2 to 50) for measuring harmonic distortion. The calculation formula is listed below. Thus, the instrument can easily measure distortion values as required by the ENERGY STAR requirements.

Inrush Current Measurement

The Model 66202 Digital Power Meter provides inrush current ( Is ) measurement function. Users can set a current level for triggering the starting point of measurement. Users also can use an external TTL signal to trigger inrush current measurement through a port of the Control-Signals on real panel. The delay parameter can help users to ignore the peak value B after the trigger point A. The parameter, T, can let users set a time period for measuring the peak value during Time T. The application is to avoid getting the inrush current value that is caused by X capacitor of a power supply.
