Gresham Power Launches ATCA Power System

Gresham Power has released the ATCA power system solution, consisting of a 1U, 19in rack mounting, three-bay power shelf and mating power modules. The ATCA power supply offers three 800W up to three 1,500W of power with 12/24/48V outputs per 1U rack-mount chassis and an optional I2C/IPMI digital interface. Advanced Telecom Computing Architecture (ATCA) is a recently introduced open-standard specification developed by PICMG.

It brings together emerging high-speed interconnection and data processing technologies while offering increased reliability and system management for communications systems. The Gresham Power ATCA power system features a universal AC input (85-264VAC) with active power factor correction compliant to EN61000-3-2 Class D, features hot-swap/redundant power modules with current power share, over-voltage, over-current and over-temperature protection circuits.

With fully ATCA-compliant LED indicators, the system provides analogue status and control signals and an auxiliary 3.3VSB power. The ATCA power source is said to offer operational efficiency up to 89 per cent and reliability of >300,000 hours to Bellcore 332 Issue 6 (30C). The power system can be quickly configured to meet customer-specific requirements for a best fit into individual applications. All models are CE marked, certified to EN60950, UL60950 and meet EN55022 Class-A emissions.
