2020: Fault-Tolerant Design Series, Part THREE

Hybrid Power Architectures using Mixed Sources for Fault-Tolerant Applications Many utility installations already contain Energy Storage Systems (ESS) for maintaining continuous operation during times when a grid supply is not available to the location. For our hybrid systems discussion, consider the ESS being a 130v direct-current (dc) source. A converter power system is used to transform dc at 130V to 48V dc in the shelf system and support the individual protection circuits. The rectifier p...

Operations Status - OPEN

Operations Status We understand your "Essential Services Critical Network" depends on power availability. The Customer Experience Center deployed new procedures to help your power conversion product arrive in a timely manner. The new process involves a simple validation from the recipient that their local and state governments have not closed the destination business. Most often this can be taken care of via email. This extra layer of pre-ship validation is intended to prevent your produc...

2020: Fault-Tolerant Design Series, Part TWO

Dual Power Systems in a Diversity Array for Fault-Tolerant Applications As the power shelf systems are paired to provide an additional fault-tolerant level of dc power support, additional diversity is realized. In this array, there are two power shelf systems each with multiple protective devices linked to load apparatus. Dual power arrays will double the control and telemetry from an installation, as both systems contain communication ports. Each system will operate independently to tr...

2020: Fault-Tolerant Design Series, Part ONE

Single Power System for Fault-Tolerant Applications The simple configuration employs a power shelf and two or more circuit protection devices, for example fuses or circuit breakers. A single power shelf system can support many A/B loads when the current requirements are low and the adequate protection devices are installed. Alternating-current (ac) diversity is managed through individual power module cord connections. Consideration given to each source of the “mains” connection can i...
