Advanced Power Supply
This advanced power supply is widely used due to its high precision, reliable performance, and overload protection circuit. This power supply provides a continuously variable, regulated DC voltage with excellent load and line regulation. The power supplies work in both constant voltage (CV) and constant current (CC) modes. Coarse and fine knobs are provided for very minute adjustments. Dual displays help continuously monitor both output voltage and current. Outputs are provided with overload and short circuit protection. The power supply operates on 220 V (±10 %), 50 / 60 Hz input.
Output Volts: 0 – 12V DC
Output Current: 0 – 5 APH61033D/5 -

Demonstration Meter
With interchangeable scales. A versatile instrument and demonstration meter that can be converted to an A.C., or D. C. voltmeter or ammeter with a selection of various ranges for each mode. With a high-quality moving coil, spring-controlled movement with full-scale deflection of 5 mA or 100 mV D.C. The long pointer has a spade end and is clearly visible from a distance. Fitted in the case with glass front and back. The instrument can be used with different dials to give different voltage and current ranges. All dials are interchangeable and each has a plug coupler to fit the instrument. The coupler connects appropriate resistors, shunts, or rectifiers to convert the instrument to the range as given on the scale of the particular dial. The scales have clear bold figures and are marked on both sides to enable the lecturer also to observe the reading from the back of the instrument. A zero adjuster allows the instrument to be used for centre zero dials. One dial of range 50-0-50mV D. C. is supplied with the instrument. In plastic case.
