Analog controls with digital stability As technology has changed, many products have moved from analog The main disadvantage of analog controls is stability and security. The controls to digital ones. Although digital controls suit many instruments, settings of analog potentiometers can drift over time. More importantly, they do not necessarily suit a bench power supply. the settings can be changed accidentally with potentially serious conse- quences. Customer research shows that many users prefer the speed and simplic- ity of conventional analog controls for setting voltage and current. The New PL series introduces S-Lock. One press of the Lock button Digital controls may offer greater precision, but often at the expense of transfers control of voltage and current from the analog controls to ease-of-use. internal digital circuitry. With this in mind, the New PL series has retained the true analog con- This offers not just complete security, but exceptional stability as well trols of its predecessor. with each setting controlled by an instrumentation quality DAC. Lock your settings Linear regulation for ultra-low noise at the touch of Linear regulation still offers the lowest output noise and the best transient a button response (recovery time from a sudden current step). Most linear regulated power supplies offer low output noise with figures below 2mV rms being typical. The New PL series goes a stage further and an rms noise figure of 0.4mV with tightly specified pk-pk noise and common-mode current figures. Choose a voltage range that suits your task When working with any particular piece of equipment, engineers often require a voltage source variable over only a narrow range. Set the voltage too high and damage might occur, set it too low and the circuit may reset. Thats where the V-Span function of the New PL series comes in. It allows the user to redefine the end-stop values of the voltage control to define a specific voltage range. For example: An engineer is working on a circuit that will eventually operate from four NiMh cells. They use V-Span to set a Vmax of 5.8 volts (to prevent over-voltage damage) and a Vmin of 3.6 volts (to ensure that the circuit doesnt reset). They now have a power supply which provides high resolution analog control over the exact voltage range they need. Vmin and Vmax can be set anywhere between zero and maximum output voltage subject only to Vmax > (Vmin + 0.1V). The fine control gives additional adjustment of 1%. Once set, the voltage span function can be turned on or off at the press of a button*.
