The original PL series set a new benchmark for DC laboratory power supplies when it was
introduced in 1980 and has since been extensively copied by other manufacturers.
Its key features were:
•
Linear regulation for ultra-low output noise and fast transient recovery
•
High accuracy four digit fixed-resolution meters
•
True analogue controls for quick and intuitive adjustment of voltage and current
•
DC output switch to check settings before applying them
•
Remote voltage sensing for exceptional load regulation
•
Current meter averaging to reduce jitter with rapidly varying load currents
The New PL series retains all the key aspects of the original PL series but combines them with
new and important features:
•
High power density - up to 90 watts from an ultra-compact 3U ¼-rack case size
•
Significantly higher energy efficiency than conventional linear regulated designs by using
an advanced phase-controlled pre-regulator
•
Low current range giving 0.1mA meter resolution and finer low current setting
•
V-Span allows the user to redefine the end-stop values of the voltage control, giving high-
resolution analogue control over the exact voltage range needed
•
S-Lock digitally locks voltage and current settings at the touch of a button
•
Setting limits can be viewed at any time
•
Safety binding post terminals are touch-proof and uniquely accept fixed shroud 4mm
plugs as well as standard plugs, bare wires and fork connectors
