Now in the third generation of family ownership E Preston Electrical continues to grow and build on traditional values.

“We work hard for our customers to get the best products at the best prices while providing exceptional customer service.  We always do what we say we will, even if that is just a call back,” says Mark Preston, MD.

This is a principle that was rooted in the business from its inception over 30 years ago by founder, and grandfather to the current directors, Ernest Preston.

Although there is still a great emphasis on these traditional values the company has embraced new technology in all of its business operations and now launches a new digital venture.  The new interactive e-shop eprestononline.co.uk is aimed at increasing accessibility to existing and new customers.

“We have access to the latest technology from our suppliers,” says Matthew Preston, sales director. “We want to make dealing with E Preston as easy as possible.  We will continue to visit new and existing customers, and speak to them on the telephone, but with eprestononline we can offer them access to our company whenever they want.”

Click AwayThe new eShop will allow customers to log in to their own portal to view orders, print off documents such as acknowledgements and invoices, and allows them to place repeat orders.  Data sheets and supplier catalogues will also be readily available.

The company believes it maintains its position as a traditional company – or more appropriately, a modern company with traditional values.

Cynergy3 SIL3 Functional Safety Incremental Encoders

Cynergy3_logo.jpg

SIL3 Functional Safety Incremental Encoders
With a robust and reliable design resulting in a wide range of secure products, which can be used in several types of configuration.

Any automated system potentially poses a risk to people, property or the environment. For this reason a number of safety measures have been taken. Safety standards have been created with one thing in mind: limiting risk.

With these standards as a framework, functional safety can, after a risk analysis, provide appropriate protection. Hazards are anticipated during the system design phase and are dealt with before they occur. These standards have evolved to increase the safety level and have been applicable since 2012.

Schurter Fuse Family UMF 250 – Rated Current Extension

Schurter Logo1.jpg

SMD Fuse for Electromobility Applications

• Extended rated current range with 15 A
• Ideal for electromobility applications
• Cycle resistant with quick characteristics
• Halogen-free and RoHS-compliant

The proven UMF 250 SMD fuse family gets extended by a 15 A version. SCHURTER is now offering the UMF 250 in a total of 15 rated currents between 500 mA and 15 A. It is particularly suitable for electromobility applications with higher rated currents.

With its quick characteristics (small melting integral) according to IEC 60127-4, the UMF 250 is the logical addition to the successful UMT 250 range. It is sealed against potting compound to achieve a hermetic seal for use in intrinsically safe applications according to ATEX and IECEx requirements. Thanks to its high cycle stability and minimal temperature derating, it is extremely robust and aging resistant.

 

Applications
Thanks to its low internal resistance, the UMF 250 is ideally suited for primary and secondary protection on SMD circuit boards. Applications of the UMF 250 include the protection of battery-powered systems with high switch-off capacities of 500 A @ 125 VDC (e.g. electromobility). The fuse is also suitable for primary protection in the AC range, for example in voltage regulator modules and charging stations.

For Lead-Free Soldering Processes
The UMF 250 is a halogen-free and RoHS-compliant fuse for lead-free soldering processes. The solder surface compatibility with the most important competitor products allows Schurter to offer the UMF 250 as a replacement product. The fuse is cURus approved. Available in 100 pcs plastic bag or 2000 pcs tape and reel packaging.

Crouzet Timers

crouzet1

A timer is a simple automation component which is used to manage actions over a period of time or control how long actions last.  The timer is a control device which triggers an action according to a time and a function.  After a predefined time has elapsed, the timer closes or opens one or more contacts. Timing cycles, whether single shot or repetitive, are started by latching inputs or pulsed inputs, allowing a wide variety of functions to be created.

Timers can be found in electrical cabinets associated with other automation functions for the following markets:

• Food industry
• Industrial automation systems
• Lighting
• Building equipment
• HVAC
• Small or large industrial machines

Schurter AEO 10.3×38 Fuse

Schurter Logo1.jpg

High Performance Fuse For Automotive Applications
• Very high rated current up to 50 A
• Safely interrupting 1000 VDC
• Versatile mounting options

With the AEO 10.3×38, SCHURTER launches a high-performance fuse for particularly high voltages up to 1000 VDC and currents up to 50 A, which is particularly suitable for automotive applications.

High voltages and high currents occur in electric vehicles in numerous places. Their battery packs with several thousand rechargeable cells store enormous amounts of energy. This in order to meet customer requirements concerning driving performance and range by still providing the shortest possible recharging times. To safeguard this level of power, you need highly reliable high power fuses. Such fuses are required, for example, in the BMS (Battery Management System), for on-board and off-board chargers, DC-DC converters and other systems exposed to high voltages.

Welding Is More Reliable
A weak point of every fuse is the connection between the melting wire and the contact cap. This connection is usually done by a solder joint. In the fuse production process, however, this technology brings quite many difficulties. Creating the connection by welding increases the reliability by far. SCHURTER uses a new, patented process which guarantees highest reliability.

Versatile Mounting Options
The new fuses of the AEO series offer a multitude of possible mounting options. In addition to the cartridge fuse, which requires a fuse clip (recommended model: SCHURTER CSO) and the classic mounting directly on a printed circuit board, screwable version for surface mounting or even axial mounting are available.

Applications Automotive:
DC/DC Converter, On Board Charger, Battery Management System, PTC-Heater and Houshold Charging Stations.
