Irwin Powerbase V8

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.

Description

  • 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

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.
