Sierra module built with ECI technology and it is a triple port converter. This module deliver pure sinusoidal output and
ripple free DC output from AC mains or battery.
The below block diagram gives an explicit description of the topology and its operation.
ECI technology has AC to DC , DC to AC , and DC to DC converters to provide constant and disturbance-free output
power regardless of the input source.
The power flows either from AC or DC source under the control of the DSP controller. Thanks to internal energy
buffering for transferring the load between two input sources by 0 ms.
In the case of a short circuit at the AC output, the converter will provide 4 x In during 20 ms to force output MCB to trip.
Breaker selectivity shall be adapted according to the power available.
Sierra module works on True Redundant Structure (TRS) that features decentralized, independent logic, and redundant
communication bus.
Each Sierra module has three levels of protection, and it will help to isolate from other modules in case of any fault in
the corresponding module. Due to this functionality in each module, it provides no single point of failure in modular
systems.
The Sierra modular systems provide quality output power with higher efficiency.
1 Information and data given in this chapter is intended to serve as an overview of the ECI Technology. Detailed features and parameters for each individual
module type in the range may differ and should be referred to in the dedicated data sheet.
