A flexible power supply designed for Primary, Middle and Lower Secondary School use. Offering 1.5, 3, 4.5 or 6V smoothed and regulated dc at up to 1A, it is the ideal next step from using cells and batteries. Four sets of terminals mean it can be used by four groups simultaneously |
1AMD £79.00 
The unit offers 1A dc per rail through multi-outputs. Seven terminals supply +15V, +12V, +5V, 0V, -5V, -12V and -15V. This gives great flexibility offering 11 single rail voltages and 33 symmetrical and asymmetrical dual rail voltages. The outputs are all regulated, smoothed and short circuit protected. Locktronics Power Supply £99.00 
| 5V 1A Current Limited £42.00 
A smoothed regulated 5V power supply which is current limited to a maximum of 1A. This makes it particularly suitable for electronics work where high short-circuit currents can damage sensitive components. Recommended for Locktronics. The unit utilises a keyswitch to select between two modes, either a fixed 5V supply for TTL , MES lamp work and most Locktronics circuits or a dual rail 15-0-15V,continuously variable output for operational amplifiers etc. The two 15V outputs may be altered independently to investigate the effect of asymmetric supplies on output. All outputs are short circuit and overload protected and output current is limited to 1A, to protect Locktronics components. Has a 4mm earth socket on the back panel for radio investigations. |
