Teledyne LeCroy T3PM1100 – AC/DC Single Phase Digital Power Meter (100 kHz)

Teledyne Test Tools T3PM1100 is a digital power meter for single-phase (1P/2W) AC power measurement. The T3PM1100 offers DC, 0.1 Hz ~ 100 kHz test bandwidth, 16 bits ADC, and 300 kHz sampling rate. The T3PM1100 features a 5” TFT LCD screen with a five-digit measurement display. It also has options to display waveform (voltage/current/power), the integration measurement function, harmonic measurement and analysis of each order (meeting the IEC 61000-4-7 harmonics measurement requirements at 50/60 Hz), external sensor input terminals, and various communication interfaces to help users to make convenient and accurate power measurements.

The rated direct input voltage of T3PM1100 is 600 V, and the input current is 20 A. The minimum current level is 5 mA (resolution up to 0.1 μA), and the power measurement resolution is 0.1 μW. The crest factor can reach 3 (half measurement range can get 6 or 6 A), and the voltage/current/power measurement capability can reach ±0.05 % reading ±0.1 % level. Different measurement modes can be selected and offer up to 25 relevant parameters for power measurement. The T3PM1100 can measure the power consumption of available products and the standby power consumption of low-power devices that require a more significant range and accuracy.

In addition, the T3PM1100 has a rich set of auxiliary measurement functions. High voltage measurements can be done using a VT rate-setting and an external voltage Potential Transformer. To measure currents above 20 A, a Current Transformer (CT) can be used, and the type of CT determines the instrument settings. When a voltage output type CT is used, measurement can be conducted through the external current sensor input terminals EXT1/EXT2. When a current output type CT is used, the CT can be directly connected to the existing input terminal on the rear panel and set the appropriate CT ratio state in the Ratio configuration menu.

T3PM1100 provides RS-232C, USB device (virtual COM), and LAN communication interfaces for remote control applications. USB host supports screen capture, accessing data stored in internal memory, and firmware updates.

The results of parameter measurement are displayed in numerical and graphical formats. The numerical design offers a general and straightforward mode to display various parameters. The available way can display 10 measurement parameters (2 main measurements + 8 monitoring measurements), and the simple method can display four measurement parameters. According to user requirements, these displayed parameters can be arbitrarily selected from 25 power parameters. The graphical format can display waveforms of voltage, current, and power. The horizontal scale can be adjusted from 25 μs/div to 1 s/div (depending on the data update rate). Three magnification levels for waveform are also provided for users to select.

In the harmonic measurement, the measurement result of each order of harmonics can be displayed by bar graphs, and a specific order can be specified for observation. The relevant values of each order of harmonics, such as voltage, current, power, voltage distortion ratio, current distortion ratio, power distortion ratio, voltage phase angle, and current phase angle, can be recorded and displayed.

T3PM1100 provides various measurement functions such as voltage, current, frequency, adequate power, apparent power, reactive power, crest factor, total harmonic distortion, and maximum current ratio.

T3PM1100 is also equipped to measure the time integral of power or current for the DUT. Users can set a time window to perform instantaneous power integration at specified intervals and then divide the value by the total period to obtain the average power of the DUT.

T3PM1100 supports automatic level changing function during integration measurement according to DUT power level to obtain accurate results.

In addition, T3PM1100 provides 4 sets of panel settings for storage/recall and memory for storing 10,000 sets of measurement values. The measurement storage can log the results based on the update rate or a self-defined time interval to facilitate the subsequent analysis. The USB host on the front panel supports screen capture, measurement value storage, and T3PM1100 firmware update.
