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...

2020: A New Year Blog and Fault-Tolerant Series

What do you see or think about when viewing 2020? Will it just indicate the year for the next 360+ days*? Maybe we are thinking about the 2020 hindsight concept or reflection of doing something, anything better the next time. Perhaps we recall a memory of vision checks when one targets the “20 line” of an eye chart, striving for laser like focus. 2020 or 202 For Me - The 2020 Series of Insight Posts will encompass design discussions using power conversion equipment in 20 squared deploym...

130 Volt Compact Power

Two (2) Pole Disconnect Circuit Breaker in Majortel 130 VDC system This 130 volt power system is designed with the integrated output circuit-breaker 2-Pole interrupt, front access operation. The two pole power block for secured screw connections is located on the system backside. The 130V circuit breaker separates both the positive and negative circuits between the compact power system output connection and rectifier bus.  Due to various 130V applications, the circuit breaker is labeled “loa...

Majortel Temperature Compensation Knowledge Bank

What is the "temp-comp" feature all about in a dc power system? The 2V cells in the big battery stacks require 3mV/cell/t° by manufacturing standards. Therefore, 0.003V per cell change (up/down) by the charging system in response to each degree variation. The calculated voltage factor is programmed into a rectifier/charging system. The factor must be adjusted to match the battery type, size and nominal voltage operation. The most common factors are listed below as examples. By Formula ...
