SOLAR ARRAY SIMULATOR
SYSTEM TO MANAGE POWER Keysight Technologies is now producing the MP4300A Series modular solar array simulator (SAS) to emulate the behaviour of photovoltaic (PV) segments. The SAS system simulates all the conditions that a craft or satellite will encounter in space with high fidelity.
Launching solar-powered spacecraft
or satellites is incredibly expensive, with little possibility of recovery or repair. These vehicles must have efficient and reliable power management systems, which often cannot be tested by using actual solar panels to provide power. Engineers must have a test solution that can verify a spacecraft’s power management system through high-fidelity PV emulation.
Keysight’s new MP4300A SAS addresses this challenge with a 6kW modular power supply, supporting fast current-voltage (I-V) curve changes with a quick recovery time that mimics rapidly changing conditions in space. According to Greg Patschke, general manager of Keysight’s Aerospace Defence and Government Solutions group, analysing power generation is an important part of the satellite design and validation process. “With the MP4300

series, Keysight gives engineers the solution they need to accurately emulate conditions in space and accelerate the testing of new PV array designs, speeding time- to-market, and reducing the risk of failure after deployment,” he says.
Alfa Laval has launched a new filtration system, the latest development in its lab and plant equipment range. As a new cross-flow skid-mounted
MULTIPURPOSE MEMBRANE FILTRATION SYSTEM /h, and testing volume ranging from
membrane filtration system that can be seamlessly connected to both up and downstream operations, the MultiSystem increases flexibility across a range of process applications. This includes the purification of proteins, sugar and starch, concentration of peptides and amino acid streams and recovery of water from condensates in pharmaceuticals and food processing. Ian Forrester of Alfa Laval
explains that until recently, membrane filtration systems would be designed specifically for the needs of each operation, which can prove not only costly, but time- consuming and difficult to integrate into the wider process. “For this reason, we developed our new
MultiSystem as a standardised offering across the pharmaceutical and food technology spectrum meaning businesses of all shapes and sizes are now able to benefit from membrane filtration technology,” says Forrester. As the largest of the lab and plant
equipment range, the MultiSystem has a test processing capacity from 100 litres/h to 6m 3
500 litres/h up to several cubic metres. Crucially, the MultiSystem can test all
filtration processes, including microfiltration, ultrafiltration, nanofiltration and reverse osmosis in batch, semi- batch and continuous modes. Diafiltration mode is also available as
standard. The module is also
compatible with Alfa Laval’s entire range of 8 inch spiral membranes, which can be quickly and easily interchanged, and features a PLC-based control
system which also enables automatic control of production sequences. This includes flow, VCF (volumetric
