Loadmaster 8000

The LOADMASTER 8000 sourcemeter allows easy setting of constant or programmable current while logging voltage on a choice of eight separate channels simultaneously. The compact design of the LOADMASTER instrument varies from other broad purpose sourcemeters by providing humidity and temperature measurements. It is ideal for multiple solar cells device testing.


FOM LOADMASTER 8000 – SOURCEMETER

The 8 channel FOM Loadmaster 8000 sourcemeter enables multiple device testing of solar cells, batteries and fuel cells combined with temperature and humidity measurements.

VERSATILE ELECTRONIC SOURCEMETER WITH EIGHT SEPARATE CHANNELS

The instrument features eight individually controlled four-probe channels and allows conventional IV tracing as well as stability studies of solar cells under different electrical working conditions, e.g. their maximum power point. Following this, it enables stability studies under the electrical conditions that apply to grid-connected cells.

TEMPERATURE AND HUMIDITY SENSING 

The FOM Loadmaster 8000 also features an input for temperature and humidity sensing using the SHT21 sensor from Sensirion. Additionally, an I2C light sensor can be connected enabling measurements of solar cell efficiency.

CONSTANT PROGRAMMABLE CURRENT

The FOM Loadmaster 8000 offers an affordable and easy way to perform multiple long-term tests of low power batteries, fuel cells and solar cells at a constant or programmable current while logging the voltage.

INTELLIGENT LOAD 

In addition to its function as a sourcemeter, a unique high speed feature can be used for applying and measuring current interrupts and peaks with a time resolution down to 20 µs (40 µs if both current and voltage are measured).

SOFTWARE CONTROL 

The FOM Loadmaster 8000 is controlled from a computer via the USB port. It can function as a stand-alone unit without connection to a PC as the data can be stored in the internal memory. LabVIEW programs are supplied allowing for out-of-the-box stability studies as well as IV characterization and high speed measurements.

SPECIFICATIONS

For each channel, cells generating currents up to 3A can be handled allowing for characterization of large cells (Maximum 13A out of, 4.5A into the channels, for all channels simultaneously). Cells can be biased from -7.5 to 24.0V and thus panels of multiple serially connected cells can also be studied.

With 16-bit resolution of ADC and DAC channels, the voltage resolution is 0.5mV and the current resolution 0.1mA, which ensures precise measurements on practically all types of solar cells.
