Absopulse Introduces 4.5kW Rack-mount Power System with Hot-pluggable 1.5kW Modules
ABSOPULSE Electronics’ PFC 4K5-3U19 Series modular, rack-mount ac-dc power supply system with PFC input delivers 4.5 or 3kW with N+1 redundancy. The series was designed for critical applications in telecommunications, power utilities and industrial control.
The 4.5kW system is built with three, heavy-duty 1.5W (PFC 1K5) power supply modules assembled on a 3U x 19" rack-mount cradle. The cradle is constructed with high-grade stainless steel and mechanical features that allow for easy insertion of the 5 x 5 x 12" PFC 1K5 units. The modules are hot-pluggable and can be inserted or removed without powering the system down.
The 1.5kW modules each accept universal ac-input voltage (95-264Vac) and are available in several different output configurations including 24Vdc/60A, 48Vdc/30A, 54Vdc/27A, 110Vdc/13A or 125Vdc/12A. Customer specified input and output voltages are available. A built-in redundancy diode allows for parallel connection to increase current available to the load, as well as for N+1 redundant operation.
The PFC 1K5 units are each equipped with an ac-module fail alarm (Form C) and a diagnostic output ON LED. They have generous design headroom and are rated for operation over a 0 to 50°C temperature range without de-rating. Each unit is cooled by a high quality built-in fan.
The modules comply with EN61000-3-2 and EN61000-3-12 directives for low input harmonic distortion as well as EN/UL60950 and equivalent industrial safety standards. They are filtered to meet EN55022 Class A EMI standards with large margins. Efficiency at full load is typically 80%. Protection features include 4300Vdc input to output isolation, output current limiting with non-hiccup type short-circuit protection and thermal shutdown with self-resetting.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
