Bench Single Generator
Frequency: 10Hz to 110HHz in four decade ranges selected by rotary switch. Output waveforms: Sine or square waveform selected by panel membrane switch with LED indication. Sine wave distortion : 0.5% typical. Square wave rise time: better than 0.25ps. Out amplitude: 0-2V r.m.s (5.6V peak to peak) open circuit. Amplitude control continuously variable rotary control uncalibrated. Built in speaker selected by panel membrane switch with LED indicator. Floating output with seperate earth terminal. Mains switch: rocker switch prominently diasplayed displayed with indicator light.
A very popular advanced continuously variable power unit now with improved specification and all the advantage of the Space saver case. Output voltage variable by rotary knob up to 25V. Continuously rated output of 8.5A a.c or d.c.Internal fan for cool running. Digital display of voltage or current for both a.c and d.c. Fully protected secondary by high speed resettable electronic trip. Slow blow fuse protection for primary. Additional thermal trip protection for transformer.
Output voltage 1-0-1V a.c. and 2V d.c. at 10A. Tolerates short circuits. Transformer protected by thermal trip and slow blow fuse. Internal fan for cool running under heavy loads. This unit replaces the westminster power supply providing high currents at low voltages and tolerating short circuits.
An exciting way to learn about optics by building and exploring common optical systems.
All the optical items can be used individually for teacher-designed investigations.
