| A high quality DC power supply providing 0 to 30V DC at up to 3A max. The instrument includes an auto-ranging digital voltmeter (DVM) with front panel LCD display, and which can also function as a digital ammeter, for monitoring voltage or current output as required according to the setting of the front panel VOLTS/AMPS selector switch. Voltage output is continuously variable over the whole range with one 'coarse' rotary control, accompanied by an additional 'fine' control which can vary output over >5% of the set value. In addition, the voltage level can be remote controlled from an external source and the output can be switched to handle continuous or dynamic loads. Current limiting is provided by further 'coarse' and 'fine' rotary controls, and with these the power supply can be forced to leave 'constant voltage' mode and enter 'constant current' mode. Here the output current is maintained for a given setting of the current control by the output voltage being varied to keep the current constant. As an aid, green and red front panel LEDs signal either 'CV' (constant voltage) or 'CC' (constant current) mode as active. Power consumption and dissipation is reduced by a multiple level power saving device which selects lower ratios of the main supply transformer secondary automatically if the output falls below the relevant threshold. The output is provided via three (+), (-) and chassis ground front panel screw terminal posts which accept 4mm wander plugs, spade terminals or stripped wires. Includes overload and reverse polarity protection. |
