Product Description
We have one new and 3 used in stock.
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.
MAIN OUTPUT(S)
