GE Signature 500 series
GE Digital Energy has announced the availability of the Signature 5000 Series, a new line of uninterrupted power supply systems for the North American marketplace.
The Signature 5000 Series is a three-phase UPS system that provides critical power protection for a range of markets and applications, including healthcare and financial institutions, industrial and biotechnology manufacturing facilities, transportation and telecommunication operations, and information technology systems.
The first phase of the North American Signature launch will be for products ranging from 10 kVA to 150 kVA. Additional products within the Signature Series are expected in 2003.
The Signature 5000 Series operates in a double-conversion mode, with true online voltage and frequency independent operation, resulting in maximum levels of power reliability.
In addition, the Signature 5000 systems can be paralleled by up to eight units using GE’s unique Redundant Parallel Architecture, achieving redundancy or increased power capacity in a flexible and cost-effective manner.
The Signature 5000 Series is built upon GE’s UPS technologies, which include extremely low output voltage distortion reducing the need for over-sizing the UPS, space vector modulation resulting in faster response and higher efficiency, s output isolation transformer separating the utility power from the load providing greater critical power protection, and superior battery management enhancing the life of the battery and reducing operational costs.
New features of the Signature 5000 Series include:
- Front-service access reducing operational footprint, maintenance and repair costs
- Enhanced cooling design increasing reliability and availability
- Integrated input filter reducing the input current distortion
- Automatic start-up procedure with user-friendly interface
Kepco RKW open-frame series
Kepco has introduced its new, 15-watt, single-output RKW open-frame series power supply with output voltages from 3.3 Volts to 48 Volts d-c. All models conform to EN 60950 for the Low Voltage Directive and meet EN 55001-B and EN 55022-B standards for conducted and radiated emissions.
Input harmonics are suppressed to meet EN 61000-3-2 by means of an active Power Factor Correction (PFC) circuit and the RKW meets all applicable Immunity and Susceptibility standards, thus eliminating a major impediment to CE Marking of the customer’s end product.
