Electrical & Electronics Everything you expect from an enclosure manufacturer... and more! innovative enclosure solutions for industrial & electronic applications www.eta-enclosures.co.uk Luso introduces SynQor’s high efficiency Hi-Rel and Quad-output DC-DC Bus Converters for military applications L uso Electronics announces the availability of SynQor’s latest Hi-Rel and Quad-output DCDC Bus Converters designed for ultra-high efficiency, reliability and performance. Awarded with key product quality and safety certifications for higher power military use, the converters operate from -55°C to +125°C baseplate temperature with no de-rating. SynQor’s new isolated/unregulated DC-DC B us Converters – the MQBQ-270-28B and MQBQ-28-28B – employ the company’s Intermediate Bus Architecture that deliver a class-leading efficiency of over 95% at full- and half-load operation with up to 400W of output power across the input voltage range. The SynQor MQBQ-270-28B and MQBQ-28-28B Bus Converters feature a continuous input voltage range of 230-400Vdc and 18-40Vdc respectively. The former creates an isolated and unregulated output voltage that is nominally 28V when the input is 270V, the latter an output voltage of 27V when the input is 28V. With each converter there is an additional droop in the output voltage of less than 5% at full load current. In a quarter brick package and input voltage range of 6-15V, the MCOTS-N QUAD is a non-isolated DC-DC converter employing synchronous rectification to achieve high conversion efficiency. The quad-output converter generates three positive output voltages (up to 30A each) Email: [email protected] www.lusoelectronics.com Manx Utilities, is a Statutory Board of the Isle of Man Government responsible for providing its customers with safe, reliable, efficient and economic supplies of electricity, natural gas and clean water; as well as collecting/processing waste water, and delivering flood risk management services.

Martindale Electric Provides a Flexible Solution to a Current Problem RCT Industrial AC Current Transducers RCTi and one negative output voltage (up to 1A), with all outputs delivering a wide trim range to offer the flexibility to the user to set custom voltages if necessary. Protection features include shutdowns for points when currents, voltages or temperatures are running too high as well as a lockout for any input under-voltage. There was an issue, however, that they could not overcome and has been a problem for many years, costing the organisation money and the electricians’ time. Their problem was finding a reliable and safe solution to measure the current flowing through Aculock fuses in a street level substation. It was obvious to engineers that regular clamp meters would not reach around the fuses and conventional flexible rogowski coils were just too thick to pass through the tube. Manx Utilities wanted a reliable solution which provided accurate measurements and complied with safety regulations. On one of Martindale’s regular visits to the Isle of Man, Martindale demonstrated a solution to these testing issues. Andy Kemecsei, Key Account Manager at Martindale Electric, met with Manx Utilities to demonstrate the new CM100 Flexi-Clamp. Manx Utilities were impressed with the initial results and decided to work with the CM100 for a trial period. The CM100 has made the previously impossible task of reaching around the ACULOCK fuse easy, instant and more importantly provides accurate measurement results. The CM100 passed the trial test period and is now in Manx Utilities list of officially approved equipment.
