Vivarail battery electric train. Vivarail have produced the Class 230 train which is converted from redundant London Underground D-Stock trains. A demonstrator unit, the two-car 230002, was fitted for diesel-electric- battery power. Vivarail developed a fast charger giving a 100 mi (160 km) range with a 10 minutes recharging time. [1]
Little Tikes is an American manufacturer of children's toys, with headquarters and manufacturing located in Hudson, Ohio. The company also has other manufacturing and distribution facilities in Asia and Europe. Little Tikes' products are mostly low-tech molded plastic toys aimed primarily at infants and young children, for indoor and outdoor ...
ESR meters fitted with protective diodes cannot be used, a battery will simply destroy the diodes and damage itself. An ESR meter known not to have diode protection will give a reading of internal resistance for a rechargeable or non-rechargeable battery of any size down to the smallest button cells which gives an indication of the state of ...
A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
An ETD on a container train in 2005. The end of train device (ETD), sometimes referred to as an EOT, flashing rear-end device (FRED) or sense and braking unit (SBU) is an electronic device mounted on the end of freight trains in replacement of a caboose.
(series resistor next to battery not shown) A track circuit typically has power applied to each rail and a relay coil wired across them. When no train is present, the relay is energised by the current flowing from the power source through the rails. When a train is present, its axles short the rails together. The current to the track relay coil ...
Encoder receiver transmitter (ERT) is a packet radio protocol developed by Itron for automatic meter reading. [1] The technology is used to transmit data from utility meters over a short range so a utility vehicle can collect meter data without a worker physically inspecting each meter. The ERT protocol was first described in U.S. patent ...
An 8-plate 160 V 450 mA Federal brand selenium rectifier. A selenium rectifier is a type of metal rectifier, invented in 1933. [1] They were used in power supplies for electronic equipment and in high-current battery-charger applications until they were superseded by silicon diode rectifiers in the late 1960s.
