Can electrical installations cope with smart home demands?

Can electrical installations cope with smart home demands?
In the last two decades electronic devices have seen a fundamental change, and so has user behaviour. Now people have more devices than ever before and they often run off the same circuit. From standard home appliances, laptops, gaming consoles, to lighting, the load on household cables is becoming increasingly higher. Thomas Kruse, Product Manager at reichelt tells us more...

Let's go back to basics with choosing the perfect regulator

Let's go back to basics with choosing the perfect regulator
Two main functions are provided in voltage regulators: changing the input voltage to a different level at the output and regulation (maintaining a constant output voltage despite changing load conditions). DC/DC Regulators are a key component in any power system, and so choosing the correct regulator is critical if an optimum solution is to be developed.

Higher performance in artificial intelligence applications

Higher performance in artificial intelligence applications
Big demanding applications such as artificial intelligence, machine learning and bog data mining are driving CPU/GPU/ASIC (‘XPU’) processor operating currents to hundreds of Amperes. As these currents increase, the remaining short distance to the XPU, the ‘last inch’ in point-of-load power architectures, have become a limiting factor in XPU performance and total system efficiency.

Stepping motor driver IC with anti-stall feedback architecture

Stepping motor driver IC with anti-stall feedback architecture
Toshiba Electronics Europe (TEE) has announced the launch of a stepping motor driver (TB67S289FTG) with a Toshiba-developed architecture that automatically detects and prevents stalling during operation. Stable and highly precise control is a basic operating requirement for motors used in printers, office appliances, banking terminals (including ATMs), cash dispensers and home appliances. Recent requirements have also emphasised more efficient motor drivers that use less power and generate less heat.

H-bridge motor driver IC supports multiple stepping motors

H-bridge motor driver IC supports multiple stepping motors
A new 4-channel H-bridge motor driver IC has been launched by Toshiba Electronics Europe that delivers up to 3.5A and 40V. The TB67H452FTG is intended for the significant and rapidly growing consumer market. As more consumer products become portable and therefore battery-powered, there is an increasing need for motors that require high drive currents with low supply voltage such as electric tools, surveillance cameras and small domestic robots.

AC/DC power supplies have industrial and medical approvals

AC/DC power supplies have industrial and medical approvals
The GSP750 series of 750 W AC/DC power supply units has been unveiled by XP Power which offers high efficiency, a peak power capability of 900 W, single outputs, intelligent fan cooling, and industrial and medical safety approvals. The GSP750 series come in a low-profile 1U-high chassis and 4x10” footprint unit, and is an excellent choice for designers looking for a fully featured 750W supply in a compact mechanical package with class-leading efficiency.

AC power sources can be customised in variety of ways

AC power sources can be customised in variety of ways
An options list has been published by distributor Powerstax which illustrates how Behlman Electronics’ fifteen BL High-Power Series AC Power Sources/Frequency Converters can be selectively customised in many ways, without the typically high cost of engineering a bespoke power supply.
