Class Packs of Brass SBC (Small Bayonet Cap) round lamp holders with an oval base.

Code: ECS8100

Our five-decade capacitance substitution box has been specifically designed for the schools market with its clear display and ease of use.

Unit will simulate capacitances from 100pF to 9.9999µF in 100pF steps
Max. voltage 50V DC
The required capacitance is set by a counter with the value displayed in µF, nF and pF
Output is via 4mm terminals with 4mm sockets
Housed in a sturdy ABS box

Code: EPU0113

A compact power supply 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. 4 units are designed to fit in a shallow Gratnell tray.

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: 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: 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.

Pack of 10 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.

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.

Supplied with 1 x 240V 100W lamp and 1 x 12V 5W lamp and mains power lead.

A heavy-duty power supply for powering laboratory experiments.
Heavy duty variable transformer and high power toroid transformer
Continuously variable output of 0 to 16Vac and 0 to 20V dc capacitor smoothed
Output current 8A. Output voltages are rated at 8A load so higher voltages are available at less output current.
Manufactured in the UK with 5 years warranty
AC and DC outputs may be used simultaneously up to rated current.
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
