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.

- 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
