OmniOn Power GPS4827

The GPS4827 capitalizes on the product strengths found in the GPS4848 and Infinity product families by integrating the highly efficient Infinity NE075 rectifier platform and the time-tested distribution found in the GPS4848 to create the GPS4827 Infinity power system. Utilizing the 1RU 75A 48V rectifiers, a fully equipped bay only requires 15.75 inches of rack space for nine rectifier shelves, allowing for as much as 2,700A of rectifiers and 48 inches of distribution. With this increased density, a single-bay GPS4827 system provides ampacity and distribution for most small, medium, and large-sized applications, while retaining all the features found with the larger GPS4848.

Bay Options

The 4827 system can be deployed with capacity of up to 2700 amps in a single cabinet or expanded over multiple cabinets to 5400 amps. Designed for either internal input AC breakers or terminal strip terminations, rectifier shelves can be spread across multiple bays or concentrated to a single bay. For greater flexibility and working space, the 4827 may be equipped with a larger 36 inch wide distribution bay to accommodate large cable termination and egress.

Unique to the GPS4827, rectifier AC terminations can be collected in pairs to reduce input AC circuit breakers by 50%. Additionally, the GPS4827 can accept 3ph input by supplying L-N across the rectifier shelf inputs at 277Vac.

Infinity Rectifier and Converter Family

The Infinity TEZ rectifier series offers modules for use in -48V applications. Rectifier:

• NE050AC48ATEZ Rectifier, 50A/48V Output

• NE075AC48ATEZ Rectifier, 75A/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 supporting up to 72 rectifiers. Remote peripheral modules can support over 500 monitoring points for OmniOn Power Critical Power or third party devices. Ethernet, SNMP, Modbus RTU, and TL1 provide integration with power engineering and NOC workflow.

As an economical alternative with similar remote monitoring capabilities, the 4827 can be equipped with the Pulsar Controller. Designed to monitor and control system components including rectifiers, 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 local/remote PC interface.
