POWER SUPPLY, TRIPLE OUTPUT, DC (0292)
It is a high performance, fully solid-state, triple output DC power supply, particularly suitable for wide range of industrial and laboratory use involving experimental set-ups and circuit development applications. The two main outputs are continuously variable from 0-32V DC at a maximum of 3A, available through 2 sets of 4mm colour coded terminals, one towards the left and other towards the right of front panel. The variable output sections can be operated in constant voltage or constant current modes, with the unit automatically interchanging between the two modes, which are indicated by separate indicator LEOs. The front panel Voltage and Current control knobs provides for adjustment in output voltage and current respectively. The front panel also has separate 3 digit LED display for each variable section to monitor output voltage or load current, selectable through meter (V / AJ selection switch. The unit also provides a fixed 5V DC output with adjustment facility from 4.5 to 5.5V with a maximum current of 3A along with overload indication. All the outputs are floating, i. e., neither the output positive terminal nor the negative terminal (nor any point within the ,circuitry] is connected to ground. Designed for continuous use.

POWER SUPPLY, EHT, 0-5kV DC (0295)
This is a specially designed universal floating high voltage power source useful for supplying charge for quantitative electrostatic experiments and also for gas discharge tubes needing a filament supply, or even spectrum tubes. Provides a continuously variable output up to 5kV by a transformer having specially insulated windings to withstand EHT voltages. The fully floating EHT circuit is particularly useful for discharge tube experiments so that the positive or negative terminal may be safely connected to earth and / or one side of the filament. The transformer is tapped directly to provide 6V/1A AC or 12V/0. 5A AC filament heating supply, which is also insulated for EHT voltages. A rotary control knob provided on the front panel adjusts the EHT output from 0 to 5000V DC with a non-hazardous maximum load capacity of 3mA [short circuit current) which can be read directly from an analog moving coil meter. All outputs available through 4mm shielded sockets and are clearly marked for their respective outputs. Both input and output fuse protected. The complete unit housed in a specially designed two part aluminium extrusion with insulated plastics side supports for safety. With indicator type ON/OFF switch. Supplied complete with detachable mains lead. Operates on 220-240V AC, 50Hz.
