Keysight Technologies, Inc. expands the MP4300A Series Modular Solar Array Simulator (SAS) with two new mainframe and module models, delivering total power up to 8.4-kW in a 2U footprint. The SAS solution is a six-channel modular platform that emulates the behavior of photovoltaic (PV) segments and simulates all conditions a craft or satellite will encounter in space with high fidelity.
Deploying solar-powered spacecraft and satellites is costly, with little opportunity for retrieval and maintenance. Therefore, engineers must design the vehicle’s power management systems for dependability and effectiveness under a variety of harsh conditions. However, it is challenging to simulate the conditions these systems will experience in space. Engineers need a testing method that can accurately validate the power management system of a spacecraft under varied conditions using precise photovoltaic emulation.
Keysight’s MP4300A SAS addresses this challenge by introducing higher power-level modules that better simulate PV performance in space. The new MP4351A auto-ranging module delivers 1.4kW 160V/10A power, while the new MP4352A auto-ranging model provides 1.4kW 80V/20A. In addition, two new mainframe modules of up to 10kW have been introduced to accommodate the increased power of the modules.
The MP4300A SAS platform offers the following key benefits: Industry-leading power density – Provides total power of 8.4 kW in 2U of rack space, reducing capital expenditures; Modular platform – Offers up to six channel outputs with flexible power and performance options; Better thermal performance – Delivers high power density, 2-quadrant capabilities, and regenerative power technology to reduce thermal challenges; Rapid deployment capabilities – Allows control of up to six channels through a single I/O port with a familiar programmatic interface to quickly build SAS systems with demanding performance requirements; Realistic simulations – Supports fast current-voltage (I-V) curve changes with quick recovery times mimicking the rapidly changing conditions in space.
