What advantages do i6A 250W non-isolated DC-DC converters offer over isolated modules?

The non-isolated i6A DC-DC converters offer power levels of up to 250W. Traditional isolated converters require a transformer and associated circuitry. As the i6A modules use a simple buck converter topology, the transformer is eliminated, which allows operating efficiencies as high as 98 percent, compared to 95 percent for an isolated converter. This reduces wasted power by 60 percent.

Automotive power distribution box testers use programmable power supplies for flexibility

As the complexity of automotive electronics continues to grow, the distribution boxes now contain more than just fuses and connector terminals. A variety of relays, both mechanical and electronic, are commonly located in the box. For reliability, quality and safety reasons 100% automated functional testing is required. Programmable power supplies are preferred as they allow the test systems to be used with multiple box types.

What headroom do i6A 250W non-isolated DC-DC converters require?

As the i6A series utilises a step-down topology to maximise efficiency, it needs to have the input voltage higher than the output voltage – this is often referred to as headroom.

High resolution electron imaging system utilises 0 to 320V programmable power supplies

Focused Ion Beam (FIB) imaging systems, using lower beam currents, are proving to be a better technology than traditional scanning electron microscopes. Without chemical etching and no signal alteration from fluorescent probes, results can be correlated with images obtained through the use of fluorescence microscopes for protein labelling.

How to use the i6A evaluation boards

There are four different evaluation boards available for the i6A series DC-DC converters – these are either populated with a positive output 14 or 20A module, or a dual output configured for positive or negative outputs and one that has additional circuitry to allow the i6A to operate in a constant current mode.

EN 62477-1 compliant 240W model added to industrial power supply series

TDK Corporation announces the introduction of the ZWS240RC-24 EN 62477-1 compliant 24V 240W rated AC-DC power supply, further extending TDK-Lambda’s industrial 10W to 300W ZWS series. This new model is certified to OVC (Over Voltage Category) III for use in fixed installations, permanently connected to the distribution panel. Applications include robotic controllers used in automotive and other manufacturing equipment requiring a higher degree of protection from input voltage transients. OVC III compliance eliminates the need for an in-line isolation transformer, saving both cost and space. continue reading »

Programmable power supplies used to charge large oil rig battery back-up systems

GenesysTM 3U
For safety reasons, oil rigs are required to have their signal lighting backed up by an uninterruptable power supply (UPS). As offshore rigs are particularly susceptible to lightning strikes due to their remote location, the loss of AC power, and hence lighting, could pose a danger to both the rig and the safety of nearby aircraft and shipping. continue reading »
