April 01, 2013 by Jeff Shepard

Delta Group has just launched its new telecom rectifier claiming the industry’s highest efficiency of up to 97.2%, a low noise emission outdoor cabinet LENI, and a controller ORION. Three new products will be revealed at Delta’s booth (Stand A49, Hall 11) at the upcoming Hannover Messe 2013 show from April 8th to 12th in Germany among Delta’s latest developments in energy-efficient solutions.

The Delta LENI outdoor cabinet offers an innovative, low acoustic noise emission design and flexible architecture for telecom applications. With superior design of air flow and smart fan speed control mechanism, the air ventilated LENI cabinet can significantly reduce the acoustic noise of 7 dB(A) compared to traditional cabinet, and provide as low as 35dB(A) in operation that suitable to install close to residential area or other critical environments.

Delta’s new telecom rectifier DPR 2900 EnergE provides efficiency of up to 97.2%. The single-phase, hot-pluggable, fan-cooled rectifier provides power density of 36.5W/in³. Integrated with the high-efficiency rectifier DPR 2900 EnergE, Delta offers energy saving solutions for network base stations, wireless applications, fixed line applications and data communications.

Delta’s new pluggable controller ORION integrates advanced, powerful functions for telecom application. The controller’s simplified user interface - a new LCD menu, web page structure, and intuitive visual look offers easy operation interface for users. The controller hardware is designed with a pluggable concept, making it easy to maintain or replace the controller unit. With iOS based Orion Monitor application software, customer can easily monitors and get power system status through convenient handheld device.

Features of the LENI - Low Noise Emission Outdoor Cabinet include; reduced audible noise level, new innovative cooling system based on air ventilation, thermal insulation 2 cm (XPS extruded polystyrene) and IP 55 protection class, multi-layer design, aluminum or steel versions; flexible and modular inside structure, and space for 150 – 190Ah batteries with dimensions (body) of – H1800 x W700 x D800 mm.

The DPR 2900 EnergE DC Power Rectifier offers; OPEX & energy saving – leading efficiency up to 97.2%, space saving – world’s leading power density 36.5 W/in³, compact dimension (H x W x D): 41(1U) x 125.5 x 269.9mm, easy retrofit to existing DPR 2700 Series installations, and is UL/cUL, TUV/CE, RoHS compliant.

ORION - Pluggable Controller features; advanced battery management, supervision and testing methods to maximize battery life, integrated PLC (Programmable Logic Controller) functions to enhance flexibility and monitoring and controlling site infrastructure, and advanced remote monitoring through LAN or modem using HTTP, SNMP or Modbus protocol.
