Power supply for use by students in advanced courses where an accurately monitored voltage or current may be required. The output voltage is selected by a rotary switch on the front of the unit output is up to a maximum of 25V. It provides 0 - 25V ac or smoothed dc adjusted by the rotary control at a maximum current of 8A. The ac and dc outputs may be used simultaneously provided the combined output does not exceed 8A.The illuminated digital display has two associated membrane switches with LED indicators. User can choose to display current (I) or voltage (V) for either the ac or dc output of the unit.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 primary.Overloads are indicated by the LED changing from green to red.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.Output voltage continuously variable by rotary control up to 25VContinuously rated output of 8A ac or dc dc is unsmoothedLCD indication of voltage or current ac or dc selectable by membrane switchesSockets accept standard 4mm plugs and shrouded plugsSnap up handle - safe to carry with one handInternal fan for cool-runningFully protected secondary by high speed resettable electronic tripSlow-blow fuse protection for transformer primaryAdditional thermal trip protection for transformerThis device is compliant to EN61010-2010 with certificates available on requestDimensions:Width: 175mm.Depth: 190mm (including cable clips 206mm).Height: 341mm.Mass: 5.9kg.
