Programmable laboratory power supply with output voltage, 0 to 40 V, and current, 0 to 5 A (PSP-405) or 0 to 20 V and 0 to 10 A (PSP-2010). Adjustable for constant voltage or constant current. Apart from adjustable current limit, an upper voltage and power output limit can be set. All settings are carried out by push-buttons and encoder knobs or via an RS232-port. Both up-to-date values and limit values are displayed on the LCD. A function for percentage change of value; with the push of a button, the output voltage can quickly be increased or decreased with a pre-set percentage rate. The key pad can be locked to prevent unintentional change. The output has a separate breaker switch and is protected against over-voltage. The power supply is over-voltage protected, short-circuit proof and protected against overheating.
