EMC and Thermal Management
Optimum heat dissipation properties combined with variable case parameters
F
ischer Elektronik is now offering its customers the new SGV K case series, which has optimized heat dissipation properties and freely selectable case parameters. The new SGV K cases consist of an aluminium bending shell and two side plates, also made of aluminium sheet with a material thickness of 2 mm. The threaded sockets integrated in the sheet metal bending shell are used for mounting a standard mainboard, mounting plate or a non-standard printed circuit board.
The case is completed by a heatsink. Determined by the application and the design of the PCBs, the fastening elements can also be attached to the bottom side of the heatsink. Optional offered mounting brackets give the user the possibility to use the case of the series SGV K for table, wall or ceiling mounting as well as in an environment with vibration disturbances.
The SGV K case series is available as standard in four different sizes and in natural colour and black anodized surface finishes. In addition, customers have the possibility
to order customized designs by specifying the case parameters (height, width, depth, position and height of the threaded bushings) and the heatsink profile. The advantage of
this cases series is that the heatsink can be selected from a wide range of heatsinks.

esigners of residential electric vehicle (EV) charging stations will now be able to reduce the cost of complying with
regulations by using chokes that exactly meet their requirements.
E-mobility is a rapidly growing market and regulatory compliance is essential for charging stations. Development of the new RV Series choke from Schaffner is backed by the company’s decades of expertise as a global leader in electromagnetic solutions that minimise electromagnetic interference (EMI) and filter out noise. The new choke has been created to offer superior levels of performance
when dampening and attenuating noise. By offering a broad range of specifications and performance choices, the RV choke enables designers to minimise costs. Costly over-design can be avoided through being able to select a solution that mitigates noise just below regulatory limits.
For different environments, the new RV Series offers the choice between ferrite (RV8140 & RV8540) and nanocrystalline (RV8141 & RV8541) core technology. Each current rating comes with eight different performance/size options, four of them designed for vertical (RV8540)
and four for horizontal (RV8140) mounting. The four windings of the new choke are typically installed as three phases and neutral. For DC applications on the
vehicle side the same choke is used – two windings of the choke are connected in series providing very high attenuation and protecting the vehicle from disturbances. The new RV Series is designed for power ratings up to 30 kW with rated currents from 16 A to 50 A per phase at 60 °C ambient temperature. In terms of certification, the RV series complies with UL/IEC 60938-1/-2 and UL 1446. Other features of the new choke include low magnetic leakage flux, excellent winding insulation and low parasitic capacitance.
schaffner.com Emitech Group invests €10m in new test centre
mitech, a French key player in environmental testing to ensure compliance with applicable standards and regulations, has opened a new test centre dedicated to the electromagnetic compatibility (EMC) of electronic equipment, as well as vehicle homologation and large system qualification.
Emitech Group laboratories specialize in environmental testing, subjecting equipment to stresses representative of real-world conditions such as extreme temperatures, high humidity, vibration, shock, dust, corrosion and other environmental factors to assess their compliance.
The new test centre is said to have the largest (27m x 18m x 10.5m) and most recent Faraday cage built in France. The facility has a 2 or 4 wheel drive chassis dynamometer
20 June 2023
for vehicles to be tested in running order, which can simulate speeds of up to 120km/h and wind speeds of up to 60km/h, with a wheelbase of up to 6 metres and a carrying capacity of up to 6 tonnes per axle, allowing test campaigns to be carried out on truck tractors or agricultural equipment. The facility includes various easements to accommodate all current and future motorisations: petrol or diesel combustion engines, micro-hybrids, hybrids and rechargeable hybrids, electricity and hydrogen. It also has a heavy load area that can support up to 40 tonnes, allowing it to accommodate construction machinery and equipment of high tonnage and volume encountered in the various sectors of defence, aeronautics, rail, nuclear and industry. This new €10 million investment is part of the Emitech Group’s strategy to support sustainable mobility. It reinforces the Group’s

skills in the evaluation of anti-pollution devices with Euro6 and Euro7 measures to support manufacturers and equipment suppliers in their objectives of lowering pollutant emissions. The Emitech Group’s testing and
engineering solutions also extend to vehicle sub-assemblies such as lithium-ion batteries, hydrogen fuel cells, powertrains, etc.
