Code: ERS8050

A six-decade resistance substitution box designed for use in educational establishments.
Additional spare or replacement leads for our Portable Appliance Tester and Checker.

Code: IPC-5865-X

Class set of 15 Capacitance Substitution Boxes. The IPC Capacitance Substitution Box (IPC-5861-X) provides the easily selection of 12 preferred value capacitors, ranging from 100pF to 0.47µF. The values range from: 100pF, 220pF, 470pF, 1nF, 2n2, 4n7, 10nF, 22nF, 47nF, 0.1µF, 0.22µF and 0.47µF. All the capacitors offer a maximum voltage rating of 50V (AC or DC), with actual capacitance value tolerances of ±5% to ±10%. The unit is housed in a robust ABS plastic case with rotary selector switch and a pair of 4mm connection sockets.

Code: IPC-0572-P

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. 
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.

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.
