Removing heat from sealed enclosures

Posted on 24-Nov-2016 15:23:21

Demand for power supplies that can withstand harsh environmental conditions does not only come from defense applications. Telecommunications base stations and infrastructure for the smart electricity grid of the future place steep demands on power supplies. These systems are subject to the extremes of temperature, dust and humidity.

Smallest 400 Watt convection cooled power supply for medical and industrial applications

Posted on 04-Oct-2016 11:32:00

The CCL400 series of highly efficient convection cooled 400 Watt AC-DC power supplies have a typical efficiency up to 94% and a flat efficiency curve over virtually the entire load range & does not require any forced air cooling. With little heat generated due to the high efficiency, the components within the CCL400 run at lower temperatures, leading to increased reliability and service life.

62368-1: Audio/video, information and communication technology equipment – Part 1: Safety requirements

Posted on 13-Jul-2016 14:02:16

With the convergence of information technology equipment (ITE), communication technology equipment (CTE) and audio/video equipment using common technology, cross platform architecture and use in similar environments, a new safety standard has been developed to replace the familiar 60950-1 and 60065 standards.  The new standard is hazard based and in several years time will be mandatory to use in demonstrating conformity to the Low Voltage Directive when the current standards are withdrawn in 2019.

Input Protection

Posted on 15-Jun-2016 11:57:41

Input protection is implemented in power supplies and DC/DC converters to ensure safe operation. The input fuse fitted within a power supply is not intended to be field-replaceable, it is rated such that only a catastrophic failure of the power supply will cause it to fail. It will not be cleared by an overload as the power supply will have some other form of overload protection, usually electronic. The fuse will often be soldered into the PCB rather than being a replaceable cartridge type fuse.
