The PL series from Thurlby Thandar is a range of 90W laboratory DC power-supply units that offers the benefits of digital technology whilst retaining true analogue controls for voltage and current. The product range incorporates the benefits of digital control, which are instantly available via the S-lock and V-span functions; the former enables the voltage and current settings to be locked at the press of a button. This architecture transfers control of voltage and current from the analogue controls to internal digital circuitry. The result is not just complete security, but exceptional stability as well, with each setting controlled by a high-resolution instrumentation-quality digital-analogue converter. The V-span function allows the user to redefine the end-stop values of the voltage control to create a specific voltage range.
