Portable Appliance Tester & Checker – PATCH

Code: EPT5001

(Portable Appliance Tester and Checker). Performs electrical safety tests on portable appliances allowing compliance with EAWA regulations. The unit performs earth bond and insulation tests on both Class 1 and Class 2 appliances, extension leads, IEC and kettle leads etc. The unit is very simple to operate and gives clear, unambiguous pass/fail indications. Complete with test leads, instructions, pass and fail labels, a Tester’s Certificate of Inspection and is fitted with moulded mains plug.

Description

A simple to use PAT machine that allows the user to perform Class1 and Class 2 insulation tests, earth bond tests at two different current levels and extension lead tests. The compact unit clearly displays the results via coloured LEDs. A single push button initiates all the tests in a 5-second cycle.

•Class 1 Earth Bond test
•Class 1 and Class 2 Electrical Insulation test
•Mains switch and circuitry test
•Extension Lead test
•IEC lead test
•Results are displayed by coloured LEDs.  Timed test period.

Comes complete with 100 pass labels, 50 fail labels, Earth Bond Test lead, Extension lead test lead and full instructions including sample inspection certificate.

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.
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.
Our additional Pylons pack contains 5 thick card sheets which once cut-out produces 5 pylons to be used in conjunction with our National Grid Kit to give your pupils a clearer explanation on how the experiment works.

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.

A stunningly effective way of teaching the basics of electrical resistance. The kit comprises of: 
  • 1 x BERT circuit board
  • 1 x PP3 battery
  • 1 x 3B pencil
  • 1 x crocodile clip connecting lead
  • 1 x eraser
  • 1 x full set of teaching notes.
  • 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

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.
