RO-5000 Solar Array Simulator Product Range
RO-5100 Solar Aarry Simulator Module
The Rovsing RO-5000 Solar Array Simulator (SAS) product range provides the following primary advantages to space customers:
- Ultra-fast dynamic response performance, the key to high fidelity to Solar Array Simulation within the space domain.
- Up to 685W of Power from a single module (137V / 5A & 68.5V / 10A).
- Class leading energy efficiency from a smart linear + switch-mode Power hybrid design, translating into less heat dissipation and therefore considerable less noise from the SAS rack as a whole.
- Compact form factor, 2740W from a single 3U high unit, with no need for additional forced cooling devices or empty space sections between stacked sub-racks
- Programmable first level protection (OVP, OCP)
Each RO-5100 SAS Module is fully self-contained with regards to inputs, outputs and its chassis thus easing configurability and management as units can be slid in and out of the rack without the need for adjusting the rest of the system.
The standard SAS Module (RO-5100) provides output voltage up to 137V covering the full range of spacecraft needs, with custom RO-510x variants available on request for higher voltage levels. The RO-5100 provides high programming accuracy; curves can be simulated with up to 4096 point resolution with up to 600 I/V curves stored in memory, with switching between curves programmed from 100ms up to approximately 9 hours. The unit provides excellent ripple and noise performance, load switch recovery time of less than 10us, and outstanding measurement accuracy. A high fidelity simulation of the actual solar array is provided both statically (voltage and current levels) and also in terms of dynamic behavior with respect to output capacitance and response time. The RO-5100 provides excellent static and dynamic performance across the principle regulation types (series switching, shunt regulation, and MPPT), providing the user with the high fidelity required to accurately simulate the behavior of the actual solar throughout its lifecycle.

The RO-5100 has been developed in close collaboration with ESTEC’s Power Conditioning department. ESTEC has received a reference instance of the RO-5100. The RO-5100 is in use on the Orion program for the European Service Module where it is a key element in the three sets of the MPCV-ESM PCDU EGSE and four sets of the MPCV-ESM SAW FEE, first deployments on the program where in early 2016 with subsequent recurrent deliveries. Also, RO-5100 based systems were delivered to Lockheed Martin Space Systems (Denver) in autumn 2016 and to Boeing as part of Boeing’s Power Special Test Equipment renewal activity. The ExoMars 2020 mission and MetOp-SG missions incorporate Rovsing’s SAS product within their EGSE. Furthermore, Turksat-6A EPS EGSE, FLEX EPS EGSE, PLATO EPS SCOE and the Galileo 2nd Generation EGSE all utilize the RO-5100.
