Description
Solid steel Small Bayonet Cap (SBC) lamp holder with a tough powder coat paint finish and a solid brass lamp holder with 2 x 4mm electrical sockets. Ready to use supplied with a 12V 24W Lamp.
Code: IV8000 The Powerbase V8 comes with a high power rotary transformer and a high specification toroid transformer replaces the original chassis transformer. The unit supplies 0-20V smoothed dc and 0-16V AC at 8 amps. The output is continuously variable and protected by a panel mounted thermal cut out. An output limiter is fitted which allows the user to preset the maximum voltage available.

Code: EPC7000

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.

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. 

Code: EPU0115PK4

Our compact Powerlock power supply now comes supplied in a 4 pack with a Gratnells deep tray for ease of storage. 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. Supplied with 2 keys.
By connecting an ac power source to one of the coils and reading the voltage from the other coil transformer action (either step up or step down) may be readily demonstrated. The efficiency of the transformer may be studied –does the efficiency change if the laminate top is not firmly fixed? What happens if it is not present? Other more esoteric effects such as Magnetostriction may also be studied.
