Demountable Transformer
This heavy duty demountable transformer can be used for the study of transformer theory and many other alternating current phenomena. This kit consists of:
- A magnetic circuit made of highly permeable U shape metal sheet, which can be closed using two clamps with tightening screws.
- Section: 40 x 40 mm with 150 mm length and 170 mm height.
- One coil of 6000 turns with maximum current of 0.2 ampere. Intermediary coil of 2000 turns output.
- One coil of 600 turns with maximum current of 2.5 ampere, which is mainly used to create the primary of transformer.
- One coil of 1200 turns, with maximum current of 1.25 ampere, fitted with intermediary 400 and 800 turns’ outputs.
- One coil of 72 turns, with maximum current of 12 ampere, fitted with intermediary 6, 30, 54 and 66 turns’ outputs.
- Power supply cable.

Demonstration Transformer Set, Advanced
The classic demonstration transformer apparatus is added with some additional safety features. Rather than the traditional mains (220-230V AC) coil we have designed a dedicated Demonstration Transformer Power Supply with fixed (25V AC) voltage and high current output to which 100-turn or 150-turn mains coil substitutes connect. The advantage is that no lethal mains voltage is involved, instead the voltages to these mains coil replacements is 25V AC and so safe. Additional AC and DC outputs are provided up to 4V for other experiments.
Includes:
- U and I Core Set
- 100 and 150 Turns Mains Coil Substitute for use with power supply ((PH50172AC/3)
- 300, 600, 600-0-600, 900, 1800 turns coils.

Demonstration Transformer Induction Accessory Kit
Includes:
- Copper Coil – With screw clamps to hold a nail for the nail melting demonstration.
- Nails – Steel flat-headed nails 65 x 3 mm or 2½ x 1/8 inch, some with a central groove making the nail thinner at that point.
- Solid and Split Aluminium Rings-Two solid and one split for the ring-launching demonstration.
- Solder Trough – Effectively a single turn coil in the form of a circular trough. Approximately 300 mm of solder is formed into a 50 mm dia meter circle to lie in the trough.

Demonstration Transformer Set, Standard
The standard demonstration transformer set allows users to use the traditional 800 turns mains coil instead of the dedicated power supply. This is a more economical option but users do not benefit from the enhanced safety features of Demonstration Transformer Set.
Includes:
- 4 U and I Core Set.
- 5 800 Turns Mains Coil.
- 6 300, 600, 600-0-600, 900, 1800 turns coils.

Transformer Stand and Core
Apparatus is designed primarily for demonstration of the basic principles of transformers. It consists of a laminated U-core with laminated I-core, both with 30 x 25 mm cross-section to form a closed core of size 105 x 140 mm. Heavy aluminium alloy stand with removable clamping rods, 2 pole pieces, each 65 x 25 x25 mm with one end cone-shaped, to accept support rod and shading ring. Poles also have a hole drilled through lengthwise to take a light beam.

St. Louis Motor Demonstration
Students can explore how a simple electric motor works by doing a series of investigations. This St. Louis motor can be adjusted so students can study the effect of voltage and position of the brushes on the commutator. This model is capable of AC & DC operation. The motor consists of a two-pole armature. The brush holder, with binding post terminals, can be rotated for experiments. The permanent magnets, supported by clamps, can be adjusted to the desired location. This apparatus requires AC/DC Power Supply and connecting leads (not included).
