Electric Car Endurance Trip
A 400hp electric sports car is being driven the 16000 mile length of the Pan American Highway. A team from Imperial College London have designed and built a sports racing car based on the SR8 made by Radical but with the 2.6 V8 engine replaced by two rear AC synchronous axial flux motors. Energy is provided by lithium-iron phosphate cells with 56kWh capacity.
Cynergy3 10kV relays are used in the "pre-charge" circuit, which charges up the capacitors in the Motor Controllers before the main contactors are closed in order to avoid arcing and current surges, when the contactors do close.
The relays are performing well above their specification with each relay initially switching 350W peak, which then reduces to 50W.
The Racing Green Endurance team claims that the car has an average running cost of one penny per mile and a range of over 300 miles. They want to get as many people involved along the way as they can, as it is just as much about showcasing the technology as it is about completing the route. A lot of components of the vehicle come from the UK and it is a showcase of what British engineering can do.
Follow the progress of this epic trip as they drive.

New Miniature RF Relay from Cynergy3
The latest series of RF relays from Cynergy3 provides a 1A carry current, at 1-30MHz, within a 21mm package size.
The 2 series is capable of switching up to 0.5A, at 1-30MHz, and isolating up to 1.5kV, DC or AC peak.
This series has been designed for antenna tuning...

The latest series of RF relays from Cynergy3 provides a 1A carry current, at 1-30MHz, within a 21mm package size.
The 2 series is capable of switching up to 0.5A, at 1-30MHz, and isolating up to 1.5kV, DC or AC peak.
This series has been designed for antenna tuning circuits in manpack RF radio sets. The small size and low weight contribute to a reduction in bulk and weight for these radio sets.
Cynergy3 manufacture a wide range of high voltage and radio frequency reed relays up to 15KV and 20Amps continuous current typically used in electromedical, test, high voltage power supply and HF radio equipment.

Submersible Level Probes used in two marine energy generation systems.
The SLP series has been used in two of the most exciting projects for generating electricity from the unlimited resources of marine currents and wave power.
Marine Current Turbines installed Seagen, the world’s first marine turbine to generate renewable, clean energy from tidal water flows, in Strangford Lough in November 2007. The multi-million project is the first of a series of major projects around the world that will use this technology.
An important stage in the installation of Seagen was the attachment of the central monopile into the solid rock below the sea bed. A SLP4AP15 was modified, such that its buoyancy was less than sea water but more that the cement grout used to fix the monopole, and used to detect when the cement grout had reach the correct depth.www.marineturbines.com
Pelamis Wave Power installed their first commercial generator, at Aguçadoura, Portugal in July 2008. This became the world’s first wave power farm in September 2008, with three wave power machines online generating 2.25MW. A total of 25 machines will eventually be added to this site.
The SLP4 is used in each of the generating chambers, to indicate ingress of sea water into the chamber.This application required the use of PUR cables in the assembly of the SLP4, as this is more resistant to sea water.
