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.
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.

Designed for use with electronic modules, transistors, amplifiers etc. (IPC-0572-P). where the current required is not more than 1A, this power supply provides a smoothed and regulated DC output voltage with a ripple typically less than 50mV. Output up to 15VDC positive and negative (with respect to zero) in 5 stepped ranges: 5, 6, 9, 12 and 15VDC. The outputs are from three 4mm sockets: positive, zero and negative, colour coded red, blue and black respectively. The outputs are switched by means of a rotating knob. Overload and short circuit protection is built in. An illuminated on/off switch is mounted on the rear panel adjacent to a fused appliance inlet. Housed in a robust metal case with a durable powder coated finish.
| 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. | Code: IPC-1402-P
This instrument (IPC-1402-P) is designed as a general purpose laboratory power supply. It has two isolated outputs which operate independently of each other.
The AC output is selected by means of a 4-position switch on the front panel. Selected voltages are 2, 4, 6 and 12V at 4A continuously, or up to 5A for periods of 1 hour. The output is supplied via a pair of 4mm sockets on the front panel colour coded white. The output is protected from overload or short circuit by a current sensing circuit breaker mounted on the front panel.
The DC output is smoothed and regulated and is continuously variable from 0V to 12V at currents up to 3A. Voltage ripple typically less than 50mV. The output is supplied via a pair of 4mm sockets on the front panel colour coded red (positive) and black (negative). The output is protected from short circuit or overload by an electronic regulator.
The outputs may be used simultaneously as long as the combined load does not exceed 3A.
Power on is indicated on the front panel by a green LED. An illuminated on/off switch is mounted on the rear panel adjacent to a fused IEC mains inlet. Enclosed in a robust metal case with a durable powder coated finish. Supplied with detachable mains lead and instructions.
A pair of graphs showing how the output voltage of this power supply varies as the current supplied is increased is included in the instruction leaflet for this instrument.
