PRODUCT OVERVIEW GPS 4827 Infinity Power System -48V DC Medium Power Plant • Medium power applications utilizing single-phase or 3-phase 240Vac input • Full featured control and monitoring capability Benefits Reliability – Distributed fault tolerance – Proven field performance – Controller continuity Intelligence – Industry leading controller features – Ethernet interface for remote access – Centralized network management Infinity Rectifiers The GPS4827 capitalizes on the product strengths found in the GPS4848 and Infinity product families by integrating the high efficiency Infinity TE rectifier platform and the time-tested distribution found in the GPS4848. Utilizing the 1U 50A 48Vdc rectifiers, a fully equipped bay only requires 15.75 inches allowing for as much as 54 inches of distribution panels. With this increased density, a single bay GPS4827 system provides ampacity and distribution for most medium and small applications but retains all the features found with the larger GPS4848. The Infinity TE rectifier series offers modules for use in -48Vdc applications. Bay Options The GPS4827 system can be deployed with capacity of up to 1800 amps in a single cabinet or expanded over multiple cabinets to 2700 amps. Designed for either internal input AC breakers or terminal strip terminations, rectifier shelves can be spread across two bays or concentrated to a single bay. In applications needing additional distribution, two more bays can be added and dedicated exclusively for distribution. For greater flexibility and working space, the GPS4827 may be equipped with a larger 36 inch wide distribution bay to accommodate large cable termination and egress. Rectifier: - NE050AC48ATEZ Rectifier, 50A/48V Output Galaxy Millennium® II & Pulsar Plus Controllers The Galaxy Millennium II controller combines sophisticated power monitoring and remote management. This flagship controller simplifies operations and maintenance while lowering administrative costs. Remote peripheral modules support over 500 monitoring points for GE or third party devices. Ethernet, SNMP, and TL1 provide integration with power engineering and NOC workflow. As an economical alternative, the GPS4827 can be equipped with the Pulsar Controller. Designed to monitor and control system components including rectifier’s converters and distribution modules via a multi-drop RS485 digital communications bus. System status, parameters settings and alarm thresholds can be viewed and configured from the controller’s front panel or PC interface. © 2013 General Electric Company. All rights reserved. Investment Protection – Module compatibility – Power shelf growth – Flexible upgrade options On Time Delivery – 4 – 6 week availability – 24/7 technical support – Standard building blocks Total Efficiency The GE Total Efficiency™ (TE) architecture reduces energy loss and lowers cooling costs by 50-70%. TE products will prioritize sustainable energy sources like solar, wind, water and fuel cells over traditional utility grid or diesel generator sources – and they will intelligently respond to smart grid information to reduce consumption during peak demand periods. Active Rectifier Management™ (ARM) and Battery Charging Optimization™ (BCO) features increase efficiency on current and legacy power infrastructures. The Total Efficiency architecture addresses issues endto-end based on our proven experience and expertise in batteries, power distribution, DC energy systems, AC-DC power supplies, and DC-DC board mounted power to deliver a solution that is more safe, reliable and energy efficient than competitive alternatives.

Infinity TE Rectifiers • Compact - 1RU form factor providing high power density (24 W/in3) • Plug and Play – installation of the rectifier in a shelf connected to a compatible system controller initializes all set up parameters automatically. No adjustments are needed. • Extended service life – parallel operation with automatic load sharing ensures that parallel units are not unduly stressed even when a unit fails or is removed. • Monitoring / control – the built in microprocessor controls and monitors all critical rectifier functions and communicates with the system controller using the...
