Solar Array Simulator (SAS) Features
- Elgar SAS system reproduces all possible solar array outputs, based on the wide variety of input conditions that an array faces, including orbital rotation, spin, axis alignment, eclipse events.
- Complete control of solar cell I/V output curve parameters.
- Each Solar Array Simulator is a fully integrated, turn-key system complete with Windows NT graphical user interface and hardware control software.
- Remote Controllable via Ethernet or optional GPIB interface using SCPI commands.
- Hardware protection the subsystems remove power in under 10 microseconds; includes circuit breakers and relay disconnects.
- Customizable configuration SAS systems have been designed and delivered ranging from desktop, 2 channel, R&D units to systems capable of controlling two 64 channel SAS systems simultaneously.
- Fast Profiling Current Source (FPCS) delivers 450W or 500W per channel with programmable control for accurate power simulation.
- Spin mode is a dynamic mode intended to provide a simulation of a spinning satellite.
- Enhanced Eclipse mode is a dynamic mode that allows the user to easily program and initiate an eclipse event with total control over all of the V-I curve parameters and dwell times.
- Operates with Sequential Shunt Regulators and Maximum Power Point Trackers
- Multiple redundant OVP/OIP layers.
