| Description |
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.

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.

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.Â

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.

| Content | 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. Â 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. Â 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.
| Box mounted with 5 x 4mm sockets for attachment to an ammeter or voltmeter to display measurements. Monitoring the voltage of each LED a graph of energy input as a function of light frequency emitted can be measured with an approximate value of Plank's constant calculated.
- Supplied with 500 lines/mm diffraction grating
- Designed and manufactured in the UK
