Resistance Substitution Box

Code: ERS8050

A six-decade resistance substitution box designed for use in educational establishments.

Description

  • Simulates resistances from 1Ω to 999,999Ω in 1Ω steps
  • The required resistance is set by selecting the correct value from six rotary decade switches which clearly indicate the value selected by the student
  • An additional 1kΩ resistor is provided connected between one of the terminals of the internal resistance and a third terminal so the unit can be used as an accurate potential divider
  • All outputs are on 4mm terminals with 4mm sockets
  • Housed in a tough ABS box with non-slip rubber feet
  • Voltage rating 250V
  • Power rating 600mW
  • Dimensions 110 x 75 x 50mm
  • Designed and manufactured in the UK

Description

Code: ERS8050

A six-decade resistance substitution box designed for use in educational establishments.

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.
Pack of 10 24V 21W Small Bayonet Cap (SBC) Radial Filament Lamps.
Solid steel Small Bayonet Cap (SBC) lamp holder with a tough powder coat paint finish and a solid brass lamp holder with 2 x 4mm electrical sockets. Ready to use supplied with a 12V 24W Lamp.

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.

Code: EPC7000

A multipurpose unit that allows the user to easily calculate Planck's constant, to measure the wavelength of coloured light, demonstrate colour light transmission through colour filters and show the diffraction patterns for various wavelengths of coloured light using a range of 4 LEDs (Red, Yellow, Green and Blue) covering the light range from deep blue at 470nm to near IR at 940nm.
