Description

Code: OPR1221

Pack of 10 12V 21W Small Bayonet Cap (SBC) Radial Filament Lamps.

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. 
Other equipment needed is two standard 4mm plugged leads and a power supply capable of delivering 2-3 volts at 1 amp.
Pack of 10 24V 21W Small Bayonet Cap (SBC) Radial Filament Lamps.
Our additional Pylons pack contains 5 thick card sheets which once cut-out produces 5 pylons to be used in conjunction with our National Grid Kit to give your pupils a clearer explanation on how the experiment works.

Code: EBR5010

BERT is a simple way of introducing electrical resistance and resistivity to a class. It consists of a circuit board that may be drawn on using the supplied pencil. Connecting the two sides of the board together by a pencil line gives a conducting track and the LED lights. The brightness of the LED gives an indication of the resistance of the path.  Drawing the line thicker decreases the resistance, as does shortening the path. Resistances in parallel may be studied and a “volume control” simply made.   BERT may also be used to test various materials to see whether they are conductors or insulators. Liquids and pastes may also be tested.  The conductivity of the class may be studied as well as how a switch works.  When you are finished the pencil lines may be removed with the supplied eraser.

Our mini national grid system is a very cost-effective way of teaching the principles used by the National Grid to supply electrical power to our homes. This kit comprises two printed circuit boards and a set of "HT" leads to interconnect them and is SELV (Safety /Separated Extra Low-Voltage) classed, which means that no part of the system is at more than 50 volts - which means it is very safe and suitable for student use. The system allows the user to compare electrical transmission at low and high voltages and the results are displayed by the brightness of the two on-board MES lamps which are supplied.
