Product Photograph - QL564 single output and QL355T triple output      

The Ultimate in Laboratory Power !
The QL series is the latest and most advanced dc power supply range from TTi - Europe’s No. 1 in laboratory power.
Designed for both bench and system use, it offers a level of performance that is unmatched at any price.
  Highest precision
Setting resolution of 1mV in up to 56 volts using high precision instrumentation quality 16-bit DACs.
Quick switchable remote or local sense for convenience. Current setting and metering down to 0.1mA.
  Quickest control
Rapid and foolproof setting using numeric entry or rotary control. Set precise values with just a few key strokes.
Non-volatile memories for fast recall of previously stored settings.  All settings are previewed before being actioned.
  Greatest flexibility
Switchable ranges provide a higher current capability at lower voltages and increased current resolution when needed.
Single or triple output models are available (triple has 2 main outputs plus one auxiliary of 2.7/3.3/5.0V).
  Lowest noise
True linear regulation with output ripple and noise below 0.35 mV in CV mode and down to 20uA in CI mode.
Regulation near the limit of measurement. Fast control loop giving exceptional dynamic performance and recovery.
  Fullest protection
User settable OVP and OCP trips with isolated alarm output signal.  Auto shutdown for fault conditions
  Widest programmability
P versions include full remote control via GPIB (IEEE-488), RS-232 and USB interfaces and include front and rear terminals.
All QL models are easily rack mounted having one third and two thirds rack-width casing (4U height) .
  Best value for money
With over 100 watts per output, the highest stability levels, and the most comprehensive features, prices for the QL series 
start at just  565 Euro (£349 in the UK).
