We are offering demountable transformer.Abbomedtm a large-scale transformer, ideal for classroom. The coils are fitted with intermediary outputs providing many transformation ratios. Moreover, one of them has a mains cable so that you do not required an external power supply unit. Consisting of : a I magnetic circuit made up of highly permeable u-shaped metal sheeting, which can be closed via two clamps with tightening screws.B section 40x40mm. Length 150mm-height 170mm.C one coil of 6000turns, 350 ohms, 1 max: 0.2a. Intermediary 2000 turns output used.D one coil of 600 turns, I max. 2.5a. Mainly to create the transformer primary. Provided with power supply cable.E one coil of 1200 turns, 12.5 ohms, I max: 1.25a fitted with intermediary 400 and 800 turns outputs.F one coil of 72 turns I max: 12a, has intermediary 6, 30 54 and 66 turns outputs. Any other coil of different turns available on request.
