<p class="bodytext"><font face="Arial" size="5"> The Thurlby Thandar PL series of laboratory bench power supplies has established itself in many countries as an “industry standard” range.PL series units incorporate digital meters with a 3.75 digit scale length (4095 counts) to provide greater accuracy and resolution than other PSUs.
Large and bright LEDs give a clear and unambiguous reading. An update rate of 4 per second provides near instantaneous response.
Separate meters are used for voltage and current, eliminating the need for meter function switches with their attendant problems of misinterpretation.
A damping switch for the current meter simplifies measurements on rapidly varying loads.</p><p class="bodytext"><font face="arial" size="2">MAIN OUTPUT(S) </p><table border="0" style="width: 496px; height: 539px;"> <tbody><tr> <td height="32"><p class="bodytext"><font face="arial" size="2">Output Range</p></td> <td height="32"><p class="bodytext"><span style="background-color: rgb(255, 255, 255);"><font face="arial" size="2">0 - 32 Volts nominal
