Code: ERS8050

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

Code: EPU0113

A compact power supply 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. 4 units are designed to fit in a shallow Gratnell tray.

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.
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-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.
