“My 10 kV power supply has an isolation rating of only 3500V, why is that?” This is a common initial reaction when reviewing the data sheet of a high voltage power supply. This note intends to explain why.Read More
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.Read More

Rail applications demand that equipment is able to withstand the harsh climatic, mechanical and electrical environments encountered on traction vehicles and rolling stock. Electronic equipment, from lighting through passenger information and entertainment, to control, safety & engine management systems require DC/DC power conversion and must perform safely and reliably.Read More
The HHP650 series of rugged AC-DC power supplies is designed for heavy-use industrial applications where an electrically & mechanically robust solution is required.Read More
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time will be mandatory to use in demonstrating conformity to the Low Voltage Directive when the current standards are withdrawn in 2019.Read More

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.Read More
Ground is ground, right? In truth, there is no ideal ground, all ground paths have inductance, resistance and noise. Managing the various ground paths interfacing with a high voltage power supply makes the difference between a good design and a great design.Read More
