Unitel Products - PowerOne Power Supply Solutions
 

Power-One’s isolated DC-DC converters provide: high efficiencies and power densities, ultra-low profiles, wide-input voltage ranges, high input-transient withstand capabilities, and start-up into prebiased loads. DOSA compliant and dedicated-bus-converter models are available.

Z-One Digital Power achieves an unprecedented level of power-system integration to enable reduced power- system component counts, sophisticated power management capabilities, and improved reliability, cost, and power density.

A multitude of parameters, such as output voltages, sequencing, tracking, and protection limits can be user defined, via hardware configuration (pin strapping and minimal external components) or programmed through a GUI or communications bus.

Z-POL™ converters are available in hardware-configurable and bus programmable versions. Wide input, and user-defined output, ranges decrease the number of models in inventory.

These robustly-designed products are available with industry-standard form factors and trim equations. Other features include: high current densities, wide Vout adjustment ranges, and extended temperature range operation.

Power-One offers a complete range of input filters to help control EMI in board level dc-dc converter applications.

In addition to providing best-in-class front-end power-conversion efficiencies, Power-One’s front ends are designed to reduce system-level power consumption.
• A broad selection of output voltages can reduce the cost and space required for downstream power conversion to application specific voltages, such as 32V to power RF amplifiers.
• Wide adjustment ranges enable users to select a bus voltage that minimizes their system-specific I²R distribution losses and increases the efficiencies of downstream DC-DC converters.
• I²C adjustability provides the option to continuously adjust the output of the front end, optimizing the bus voltage in response to dynamic operating conditions to further reduce I²R distribution losses and increase power-converter efficiencies.

AC connection options include backplane-mounted hot-swap connectors and front-mounted IEC receptacles.
Selected products utilize the same packaging and backplane connectors for both AC-input and DC-input versions. This common-package approach facilitates DC-input front ends that will operate in existing AC-input systems with minimal rack hardware changes.

Power-One’s advanced designs also facilitate delivery of full-rated power with minimal cooling requirements. This provides greater overall-system layout flexibility as power supplies do not have to be located directly adjacent to a system fan.
In some applications, the need for a dedicated power-supply cooling fan may be completely eliminated. This added design flexibility can be especially beneficial in space constrained 1-U “pizza-box” enclosures.
 

Flexible modular products provide application-specific solutions with little-to-no NRE expenses, accelerated time to market, and increased reliability through the use of proven off-the-shelf chassis and modules. Please select the modular products tab to view our configuration tools.

Power-One’s linear power supplies incorporate rugged, proven designs to provide highly-regulated, low noise and ripple, DC power sources. These products are approved to international regulatory-agency standards, and are CE Marked to the Low Voltage Directive (LVD).
