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.

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.
|
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.

Students often think that the brightness of a lamp is only dependent on the current flowing through it. The unit allows the teacher to safely switch a 12V lamp in series with a mains lamp and study the current flow through them.

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.

| This includes kit includes the use of a safety mains lamp socket, which has a built in a switching system that only allows it to be switched on when a lamp is inserted. We have also included two switches, which must be pressed simultaneously to route the mains current through the low voltage lamp. Furthermore, the switches are sited at opposite ends of the case, requiring two hands to operate them. However, it must be appreciated that you are working with potentially lethal voltages and currents and therefore extra care should be taken.
