Description

Code: ELB8000

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.  

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.

Code: EPU0115

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.

Pack of 10 12V 21W Small Bayonet Cap (SBC) Radial Filament Lamps.
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.

The Irwin Tapped Battery Holder holds 4 x D (R20) batteries with outputs at 1.5, 3, 4.5 and 6V. Batteries and leads not supplied. Each output has a 4mm socket. Manufactured in the UK from premium strong perspex.
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.

A demountable transformer kit is an ideal way to demonstrate transformer action.  The kit comprises three coils, one with 300 turns, one with 600 turns and one with 1200 turns. These slide onto a laminated steel frame to form several possible transformer configurations.
