Source Measure Unit - Low Power 8 Kanal - Datenlogger - MPPT

The infinityPV Source Measure Units offer cutting edge technology for precise solar cell characterization and research, redefining precision and efficiency in testing. With multiple input channels, customizable power options, and intuitive software, they provide unparalleled flexibility for optimizing solar cell devices and modules. The Source Measure Units offer full maximum power point tracking (MPPT) on all channels, coupled with 4-quadrant operation and 16-bit resolution across multiple ranges, ensuring high accuracy and versatility. Beyond these core features, the Source Measure Unit is equipped with additional channels allowing for easy integration of a temperature/relative humidity probe as well as a 5-channel general purpose datalogger. The datalogger supports a wide range of inputs (4-20 mA, 0-1 V, 0-5 V, 0-10 V to Pt100) and outputs (5 V, 12 V, and 24 V), enabling comprehensive data collection and user formatting.

Zubehör

• CalCell Reference Device — a calibrated photodiode and filter to calibrate light intensity precisely at your sample’s position. Unlike internal reference diodes, the CalCell accounts for factors like sample geometry, fixture, and position, ensuring confidence in your experimental results.

• Temperature and Relative Humidity Probe — a temperature and relative humidity probe that logs temperature and relative humidity data over time, providing valuable environmental insights.

Unmatched Flexibility

Experience unmatched flexibility with the Source Measure Units, enabling independent maximum power point tracking for each channel in asynchronous mode. Moreover, our synchronous mode permits simultaneous scanning of all channels at the same voltage, facilitating the study of multijunction devices requiring synchronized recording. Select from a range of options to meet your specific requirements, including a low-power variant (200 mW/channel, 2-point measurements) and a high-power variant (5,000 mW/channel, 2/4-point measurements). Both models feature a user-friendly 5-inch touch display, providing real-time insights from the temperature/humidity probe and datalogger, alongside recent data records.

MPPT Tracker

Maximum Power Point Tracking (MPPT) ensures that the solar cell operates at its maximum power point (MPP). In this mode, the solar cell functions under realistic conditions where power is actively extracted, unlike when the cell is in an open circuit or short circuit state. The infinityPV IV and Lifetime Software allows the operator to set a minimum and maximum voltage (searching range) for a specific channel and activate Maximum Power Point Tracking (MPPT tracker mode). The SMU then initiate a perturbance and observance (P&O) MPPT algorithm for that channel, adjusting the channel's output by a few millivolts every second and measuring the current at each new point. By comparing the power at the new point with the power at the previous point, the algorithm determines the direction of the next voltage adjustment, ensuring optimal performance.
