Irwin De-Mountable Transformer

By connecting an ac power source to one of the coils and reading the voltage from the other coil transformer action (either step up or step down) may be readily demonstrated. The efficiency of the transformer may be studied –does the efficiency change if the laminate top is not firmly fixed? What happens if it is not present? Other more esoteric effects such as Magnetostriction may also be studied.

Description

Code: L1017

A demountable transformer kit is an ideal way to demonstrate transformer action.  The kit comprises three coils, one with 300 turns, one with 600 turns and one with 1200 turns. These slide onto a laminated steel frame to form several possible transformer configurations.

AC Magnetic Field Coil
Code: IV8000 The Powerbase V8 comes with a high power rotary transformer and a high specification toroid transformer replaces the original chassis transformer. The unit supplies 0-20V smoothed dc and 0-16V AC at 8 amps. The output is continuously variable and protected by a panel mounted thermal cut out. An output limiter is fitted which allows the user to preset the maximum voltage available.
Pack of 10 24V 21W Small Bayonet Cap (SBC) Radial Filament Lamps.

Code: EPU0115PK4

Our compact Powerlock power supply now comes supplied in a 4 pack with a Gratnells deep tray for ease of storage. Offering 2, 4, 6, 8, 10, and 12 volts at currents of up to 5A. Both dc and ac outputs may be used simultaneously up to the rated output. The output is protected by a push button cut-out. The unit is 2A fused on the back panel and comes complete with a moulded mains lead and plug. Supplied with 2 keys.
