Description |
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.
|
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.

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.

The Powerlock power supply has both a lockable AC and DC outputs ranges by a simple key making it impossible for students to change the voltage. The Powerlock offers 2,4,6,8,10 and 12 in both DC and AC. Outputs may also be used simultaneously up to the rated output required. For safety, the output is also protected by a simple push button cut-out. Each unit is supplied with 2 that can be used on all Powerlock units if needed. Supplied with 2 keys.
| Other equipment needed is two standard 4mm plugged leads and a power supply capable of delivering 2-3 volts at 1 amp. |

| 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.
- Supplied with 1 x 240V 100W lamp and 1 x 12V 5W lamp and mains power lead.

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.
