2-12V AC/DC Powerlock

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.

Description	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.	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.	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.		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.	Other equipment needed is two standard 4mm plugged leads and a power supply capable of delivering 2-3 volts at 1 amp.
Content	Output voltages AC & DC 2,4,6,8,10,12 voltage range in AC and DC Current 5A Voltage type - Stepped Output type - Full wave rectified, non-regulated Push button trip reset Mains input 230/240V AC, 50Hz Supplied with mains plug and lead Manufactured in the UK	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	Code: L1017 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.	Code: EBH0004 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.	A robust power supply for powering laboratory experiments. Heavy duty toroid transformer Small footprint - 4 units fit in a Gratnells deep tray Powder coated steel case Switched output of 2V, 4V, 6V, 8V, 10V and 12V ac/dc controlled by a key lock Two keys supplied with each Powerlock. Common key profile – any key fits any Powerlock Total output current of 5A AC and DC outputs may be used simultaneously up to rated current Colour coded 4mm sockets Push button cut-out Manufactured in the UK	Code: ENG1050 Our mini national grid system is a very cost-effective way of teaching the principles used by the National Grid to supply electrical power to our homes. This kit comprises two printed circuit boards and a set of "HT" leads to interconnect them and is SELV (Safety /Separated Extra Low-Voltage) classed, which means that no part of the system is at more than 50 volts - which means it is very safe and suitable for student use. The system allows the user to compare electrical transmission at low and high voltages and the results are displayed by the brightness of the two on-board MES lamps which are supplied.
