<P>The Aim-TTi PL155-P offers remote control and read-back using analog, RS232, USB, LAN (LXI) interfaces. They retain all of the capabilities of the New PL Series when under manual control.</P><P>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.</P><P>That‘s 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.</P><P>An engineer is working on a circuit that will eventually operate from four NiMh cells. They use V-Span to set a Vmax of 5.8V (to prevent over-voltage damage) and a Vmin of 3.6V (to ensure that the circuit doesn‘t reset). They now have a power supply which provides high resolution analog control over the exact voltage range they need.</P>
