PA401.2: TWO Systems Landed on ONE Bus Bar Array Using dc power systems1 in parallel connection to a bus bar array is one of the most common design architectures2 deployed for redundancy. A very common product conversation starts with the question along these lines; “Need to know if I can run two systems to different breakers on a panelboard as a redundant scheme?” Nutshell Answer: “YES, you can operate two systems connected to a common dc bus bar (panelboard) through individual ci...
Quick Set Series: Majorsine Primary INPUT Source Programming. The Quick Set Series procedure is for inverter applications where a primary input source is changed by the user of the inverter. The programmed mode is retained by the inverter processor. A future start-up will reference the saved selection. Preparing to use this feature requires the inverter to be installed with BOTH the dc voltage and ac voltage input sources. The inverter shall be powered, initial commissioning complete and...

Quick Set Series Focus: Battery Mode and Battery Parameter Settings How: From the from MTS-Com Front Panel Administrator Menu Key Steps: Select DC Limits – Screen will display the High and Low threshold limits for DC output parameters. o Press the DOWN arrow button twice to move the cursor to the Ext Equipment screen o Highlight BATT/LOAD (default is Load) and...
PA202.1: Single Converter System using the MTD48/50-130-1U converter power system. DC/DC Power Architecture Series Cynosure: • DC power supply to single point apparatus, possible distribution sub-panel to individual loads/over-current-protection-devices. Single steady state output voltage. • DC power supply to A/B connections utilizing the dual-output circuit breakers. This pre-configured system will operate in 100% duty cycle mode to convert 130vDC to 48vDC. The system kit includ...
PA401.3: Load or Battery @ 125 Volt DC using the MTS130/20AT-1U rectifier power system. Power Architecture Series Cynosure: • DC power supply to single point apparatus, possible distribution sub-panel to individual loads/over-current-protection-devices. Single steady state output voltage. • DC charge supply to a specific battery connection or dc bus with temperature compensation feature active to regulate the output voltage. This pre-configured system can operate in one of two mode...
601.2 Project Code Name: Oregon AC-to-AC; ESS/Batteries Sized per Run Time This power architecture series edition is a combination of configurations 401.2 and 101.1 as previously discussed in this document. The user's project, code name Oregon, is a deployment for 2021 and beyond. A typical control and instrumentation network, with multi-node design, is operating on the foundation of this power solution. One rectifier full-chassis system (401.2) is sized to 50 amp output incorporating feature...
"Drinking Our Own Kool-Aid"; otherwise a reference to using our power gear. Why NOT! Sure one can size the redundancy and resilience of a critical application using the products in a complete power portfolio. I have often been questioned about using the Majorpower products for a critical application. The answer is easy, "YES WE DO use these products in our operation". When it comes to our critical interconnect points, we want to be connected. Our team performs daily actions required in...
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...
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...
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...
