General common characteristics: These accessories are required in a large number of Laboratory experiments and their use is described within the related Instruction Manuals. Where applicable, they are equipped with an Educational Terminal Board on top of which the internal logic is printed to facilitate their understanding and use. Connections are performed through 4mm safety terminals. They are all designed according to the current safety standards, ELECTRON quality guidelines and for easy, user friendly integration with the product line. A4810 - PARALLELING BOARD. This instrument allows paralleling of two three-phase AC generators, or one generator and one line, by comparing their voltages and frequencies and indicating whether and when they are compatible as far as their sequence, values and phases are concerned. Only then it is possible to connect the two sources. It can be used with the lamps bright or lamps dark methods. Electrical characteristics • • • • • Three lamps, one each phase 15A fuse on each phase OFF-ON switch Nominal Voltage: 100 - 380V Weight: 0,5 Kg Ordering Code A4810 Paralleling Board (Factory Code SINC/1) ELECTRON S.R.L.

It comes with all necessary accessories to fasten the machines on the base and a safety guard to cover the coupling joint. The machines are mounted on two parallel rails fixed on the base, and can be shifted longitudinally to adjust their optimum respective distance for smooth coupling. A4840-S A4840-M A4840-L A4840-SG Ordering Codes On request, an extended base may be supplied that can host a third machine or device. For S series machines For M series machines For L series machines Extra safety guard suggested to cover the protruding shafts in case of double shaft ends machines A4840RL - ROTOR LOCKER It is mounted on the coupling base rails and has a fixed coupling joint that mating with the motor joint blocks its rotor to allow execution of short circuit tests.

Provides a convenient means to move equipment within the laboratory Ordering Code A4840TR Trolley A4880 - TACHOGENERATOR The tacho-generator is a DC generator which produces a DC voltage that is directly and linearly proportional to its speed. The standard ratio is 20V per 1,000 RPM, max. 6,000 RPM. Other ranges are available on request. It is normally used to measure speed of rotating machines, in place of an electronic or manual RPM meter, by measuring its output with a precision voltmeter and converting it to RPM’s. It is available in two versions: . an industrial version, to be mounted coaxially on the machine under test . an educational version, with base and half coupling joint to be mounted on the coupling board and coupled to the tested machine.

The flywheel is available in three different sizes to be coupled to our standard powers electrical machines. A4890 - CABLE SET It has its own support and joint for coupling on the coupling base to the electrical machine under test. Ordering Code A4885-S For S series machines A4885-M For M series machines A4885-L For L series machines Composed by the following set of 60 cables, a quantity and mix suitable to perform even the more complex electrical machines laboratory experiment. A set of 50 adapters, 2mm male to 4 mm female, is optionally available to allow the use of this set of cables on 2mm sockets. This is especially useful with the A21 M200 Industrial Installation Trainer. The cables have 4mm safety terminals according to IEC safety standards. A cable rack can be ordered optionally for orderly storing of the cables.
