| Description | 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. |
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 very popular and compact Westminster power supply that is ideal for school use in Key stage 4 and 5 physics lessons with its tough steel case protected by a tough powder coated finish that will last years of use. The unit will deliver up to 16A AC or DC through its colour coded terminal posts. This power supply is very popular for use in electromagnet experiments.

BERT is a simple way of introducing electrical resistance and resistivity to a class. It consists of a circuit board that may be drawn on using the supplied pencil. Connecting the two sides of the board together by a pencil line gives a conducting track and the LED lights. The brightness of the LED gives an indication of the resistance of the path. Drawing the line thicker decreases the resistance, as does shortening the path. Resistances in parallel may be studied and a “volume control” simply made.
BERT may also be used to test various materials to see whether they are conductors or insulators. Liquids and pastes may also be tested. The conductivity of the class may be studied as well as how a switch works. When you are finished the pencil lines may be removed with the supplied eraser.

Pack of 10 24V 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. |

- Colour coded 4mm sockets.
- Maximum voltage limiter operated by Allen key
- Push button cut-out to protect against overload and short circuit conditions
- Available in Irwin Blue or transparent case
- Mains Input 230V, 50Hz
- Fusing: 5A mains plug fuse
| 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.
