Solar array simulator - Nanosas35

Home » Solar array simulator

Description

Solar array simulators are designed to be adapted to the powers involved in Nanosatellites applications.

Solar array simulators are used for testing and development of modular Power Conditioning and Distribution Units (PCDU) and other Nanosatellite applications.

NanoSas 35 provides simulation of an adaptable and independent number of solar array power sections delivering each up to 30W.

Each module is a DC power source that simulates the output characteristics of a solar array cell. The NanoSas 35 is primarly a current source with very low output capacitance and is capable of quickly simulating the I-V curve.

NanoSas are provided alone or inside a rack of 5 modules (cf picture)

The module is controlled via USB

Drivers and MMI are provided for an easy handling from a computer
