A recent medium power (2 X 6kW DC output) floor-standing outdoor charger of our own design.

This unit was designed for shore power applications in rail sidings, to allow the
servicing of trains without their engines being run to provide electrical power.

This unit is one of three units supplied to a major UK train operator.

The environmental impact of operating train engines in depots during servicing and repairs has become a problem for most operators. The exhaust fumes are not pleasant for people in and around the depot, and the deposits of soot and oil that accompany these operations cause damaging pollution.

The engine makers are also finding that prolonged idling of highly turbo-charged engines produces ring and bore glazing, which in turn brings increased oil consumption and ring blow-by, resulting in increased running costs and maintenance.

These new charger/shore supply units are enabling one operator to carry out servicing and cleaning with no engine running. The charger provides a controlled output voltage that is held at a level suitable for battery charging and also supporting on-train loads such as the systems electronics etc. The output power as supplied is 2 X 6kW at 29V DC, continuously rated.

The cabinet will accomodate outputs up to 20kW with no increase in size, and up to 30Kw with increased height. The charger shown is for 3-phase operation, but single-phase can also be supplied, with input voltages up to 600V AC.

The charger is for fully outdoor operation, and also has external floodlighting and BS4343 240V sockets for on-train cleaning using conventional vacuum cleaners. The controls include isolators for the sockets and floodlights, plus there is a remote emergency shut-down facility built-in.

Output cables and sockets are stowed safely on external stainless-steel reels and the connectors can be locked into the top cabinets on each side.
