Pack Of 1
Rate this Product:
This power supply has been designed for electrostatic experiments including ionisation and for driving vacuum devices such as the Deflection e/m tube. The output is 0 - 5000V which is rotary controlled and limited to 2mA and there is a second output limited to 50µA.A 6.3V ac output is provided for the heater/filament of vacuum devices.It has a digital backlit display showing voltage in kV.The internal quiet-running fan will hardly be noticed but it reduces the already low thermal stress in the unit still further ensuring long life of the instrument. Triple protection is provided by a resettable electronic overload trip thermal transformer trip and slow-blow fuse on the primaryThis power supply is intended for for school experiments in electrostatics to power simple spectrum tubes and to work with Teltron tubes where a low voltage heater/filament must be powered.The EHT and the ac outputs may be used simultaneously as required by the apparatus connected. The continuously variable 5kV output is fully isolated.The mains cord is kept tidy by means of the cable retainer on the back of the unit which allows the cable to be stowed away neatly with the use of winding hooks and a clip to secure the cable.Certain vacuum tubes require more than 2mA to drive them and these tubes cannot be used with this EHT supply.EHT output continuously variable by rotary control6.3V ac output maximum current 3A3 digit LCD indication of the output voltageSockets accept standard 4mm plugs and shrouded plugsIlluminated mains on/off switchInternal fan for cool runningTime delay fuse protections for transformerThis device is compliant to EN61010-2010 with certificates available on request.
