Most laboratory power supplies quote
impressive figures for load regulation.
Unfortunately, the impedance of the
connection leads can make this a nonsense for regulation at the
load.
If the current is high, the meter will show
a significantly higher voltage than the load is actually seeing.
(for example, two 0.02 Ohm connection leads will drop 120mV at 3 amps).
The New PL Series has easy access remote
sense terminals - unlike many general purpose laboratory power
supplies - to ensure perfect regulation and meter precision. |
