One SMD fuse for use in both primary and secondary circuits streamlines processes

Schurter announces several new current ratings to its already popular UMT 250 series, for a total of twenty two unique ratings from 80mA to 10A. The series is designed to provide overcurrent and short-circuit protection in both primary and secondary circuits. The versatile one package solution streamlines design, procurement and automated assembly processes.

The UMT 250 maximizes circuit protection while its extremely compact size meets the demand for saving space and facilitating production. It can be mounted on both sides of the printed circuit board. Its low profile increases production rates when mounted with pick and place assembly machines. It is an ideal substitute for axial and radial leaded through-hole fuses where bending leads can cause assembly delays.

The Universal Modular Fuse (UMF) is time-lag (T) characteristic. It is rated at 250 VAC and 125 VDC, according to IEC and 277VAC and 250 VDC, according to UL. The series has a high breaking capacity of up to 200A at rated voltage. It is RoHS compliant and carries all the main approvals such as VDE, UL Listing, cURus, PSE Jet (Japan), CCC (China) and KTL (Korea). Applications include protection of power supplies, storage systems, wireless base stations and many other electronic systems.

The number of uses for Bulgin’s 400 Series Buccaneer waterproof connectors has grown with the introduction of fully assembled cables using over-moulded cable connectors.

Using over-mould technology a secure, reliable and tamperproof cable termination is created which is dust and waterproof to IP68.  The two new cable connectors, PX0400 - flex, and PX0401 - flex in-line, allow secure connections to be made with in-line cable assemblies or cable to panel assemblies and are completely compatible with the current 400 Series panel connectors PX0412 and PX0413.

Over-moulding also provides a strong, durable strain relief around the cable functioning through a temperature range of -20°C to +85°C, while the polyurethane over-mould material has been tested and validated for use on PVC and polyurethane cable jackets.

These cable assemblies provide a secure interconnection system for OEM’s who may require a ‘customer-proof’ solution, so are ideal for ‘fit and forget’ applications such as instrumentation, marine, medical, surveillance and CCTV.

The wide range of potential options, including cable construction, length, number of poles, flex or flex in-line connectors, may be combined with any other type of connector to provide an assembly to meet exact system requirements.

Schurter presents a breakthrough product, providing simple and universal EMC for high frequency applications, using X2Y® filter technology. Series 5150 possesses broadband suppression properties to 1 GHz and combines them with the most simple and universal power input.  This integrated and compact design provides an easy, safe and cost effective alternative to existing market solutions and opens new opportunities in the filtering of high frequencies.

Until now, X2Y® filter technology is known only for EMI protection in DC circuits. With the introduction of the Schurter 5150 series, the application of X2Y® is now extended to the area of AC power input. The technology is applied in place of X and Y capacitors, typically used in line filters today. It combines the X and Y capacitors into one component, thereby eliminating the leads connecting the capacitors and reducing parasitic impedances to a minimum.  This results in broadband suppression into high frequency ranges.

The double shielding between the X2Y® filter and filter casing, together with the broad metal flange can serve as an alternative for feed-through and multi-stage filters.  The compact package is designed for front- or rear-side mounting and uses the same panel cutout size as a typical filtered AC inlet. Filter variations include types for standard, medical and industrial applications.

The breakthrough design of the 5150 is the first of its kind to be safety agency approved for use in AC applications according to IEC and UL. It is ENEC approved up to 10 A 250 VAC and cURus approved up to 15 A 250 VAC.  Application examples include equipment for measurement engineering, data encryption, medical engineering, IT and telecommunications. It is suitable for use in office and medical applications in accordance with IEC/EN 60950 and/or 60601-1.

E-T-A Circuit Breakers has introduced a new version of its compact ESX10 electronic overcurrent protection product for automation applications. Designed to reduce costly downtime and danger to personnel on production lines, the new ESX10-T is ready for direct rail mounting, singly or in groups. Single or group signalisation is quickly attainable.

The type ESX10 Electronic Circuit Breaker provides electronic overcurrent protection according to UL2367 for 24V DC control circuits and load currents from 1A to 12A: in the event of overload or a short circuit, the faulty load will be disconnected electronically by means of a mosfet in the output circuit of the protector. It ensures selective disconnection of 24V DC switch-mode power supply (SMPS) loads while optimally matching the application requirements.

The E-T-A ESX10 provides active current limitation to 1.8 or 1.5 times its rated current. This allows capacitive loads of up to 20,000μF or lamp loads to be switched on without affecting other loads on the power supply. At the same time, this electronic active current limitation responds much faster to overload or short circuit conditions than switch-mode power supplies: the ESX10 will shutdown electronically a single faulty output, while allowing all other load circuits connected to the same SMPS to continue working as normal.

The E-T-A ESX10-T is just 12.5mm wide and can be mounted directly on a DIN/EN rail. All electrical connections are then made by means of convenient screwless terminals. Status indication is provided by a multicolour LED plus an integral short-circuit proof status output or potential-free signal contact. In the event of an overload or short circuit, the load circuit may be re-activated electronically via a re-set input, or by a manual ON/OFF button. The ON/OFF button also allows manual disconnection when starting up a system or during maintenance.

For processes powered by 24V DC switch-mode power supplies without circuits protected by a device such as the ESX10, an overload in a single circuit will cause the power supply to shut down the output to all the circuits it supplies. On recovery it may go into ‘hiccup’ mode. Costly downtime, scrap and even danger to personnel may result. Traditional protection solutions do not provide the answer. Circuit breakers with fast operating characteristics would be likely to cause nuisance trips during current peaks and switching on of capacitive loads. On the other hand MCBs are too slow, and neither delayed operation nor high performance circuit breakers will respond adequately in this situation to overcurrents. The power supply will therefore switch off completely, bringing all connected loads, i.e. the entire system, to a standstill.
