On track for rail success POWER
Make intelligent battery choices
Yuasa Battery Sales (UK) has announced a new family of intelligent battery chargers designed to enable charging of all types of lead acid batteries including industrial VRLA, automotive,motorcycle and cyclic types used inmobility scooters and golf trolleys.
The YuPower range features sixmodels encompassing
Martek Power introduces several newrailway qualified products. TheMBRH series extends the established PowertronMBR series to an output power of 25Wwhile retaining the same physical envelope andmechanical platformas existing 15W models. These fully encapsulated DC/DC converters are available in single and dual output configurationswith outputs fromfive to 48V. Allmodelsmeet railway industry standards: RIA, EN50155 and EN50121.3.2with no additional external components required for EMI filtering and 10ms EN51055 S2 hold up time.
The JL series has also been expanded with the new JLMand JLHMunits rated
at 35 and 50Wrespectively. They boast all the features of the standard range, including full EN50155 compliance, but in a smaller footprint. The open frame version of both productsmeasures 115 by 85 by 22mm, which is less than half the overall size of the original units. Output voltages fromfive to 110V are available and all typical railway input voltages are catered for.

900mA 12/6V formotorcycle batteries, through two amp six and 12Vmodels, four and eight amp 12V chargers to a four amp 24V unit. Apart fromthe 900mA 12/6Vmotorcycle battery charger, allmodels utilisemultistage and hybrid charging techniques to ensure optimumcharging.
Features include soft start technology to protect both
battery and charger, automatic desulphation for prolonged battery life andmultistate charging to deliver 100 per cent state of charge. Chargers of four amp and above are supplied with Torbury connectors with a Torbury to crocodile clip converter, while themotorcycle and two amp chargers feature standardmotorcycle connectors. A charger accessory adaptor is also available to allow connection to common golf trolley battery connectors.

Conformally coated versions of Excelsys Technologies' Xgen user configurable power supplies are now available. Devices have also been HALT tested for resistance to shock and vibration and characterised over an extended operating temperature range,making them ideal for COTS/MIL applications and extreme industrial installations such as vehicle and
ship based communication and IT systems, industrial control systems and test and measurement equipment.
Boasting power density of 17W/in³ and
efficiencies of 90 per cent in a 1U package, the Xgen series provides power solutions from 200 to 1,450W.
