OUTPUT PROTECTION

Output Protection: Output will withstand forward voltages of up to 20V above rated output voltage.
  Reverse protection by diode clamp for currents up to 3A.
Fault Condition Trip: The output will be shut down if any of the four trip conditions listed below occur.
    (In addition to the output being set to Off, an isolated rear panel signal is also activated.)
  Over Voltage (OVP): Settable 1V to 40V (QL355) or 60V (QL564) in 0.1V steps
  Over Current (OCP): Settable 0.1A to 5.5A (QL355) or 4.5A (QL564) in 0.01A steps
  Over Temperature: Monitors internal temperature rise to protect against excess ambient temperature or blocked
   ventilation slots.
  Sense Error: Monitors the voltage between the remote sense terminals and output terminals to protect against
   mis-wiring.
Trip Output Signal: Isolated open-collector output signal on rear panel.

METERING

Display Type: Dual digital displays per output using 14mm (0.56") high brightness LEDs.
  5 digits for voltage, 4 digits for current. Update rate 4 per second.
Meter Function:
  Voltage meter shows set voltage when in CV mode and measured voltage when in CI mode.
  Current meter shows measured current when in CV mode and set current when in CI mode.
  Limits Display: With the dc output switch set to Off, both meters show the set values (i.e. the limits).
   With the output On, either the voltage meter or current meter will show a measured value (depending on the CV/CI
   mode). Pressing the Limits button will provide a temporary display of the set values.
Watts (VxA) Display: The voltage meter can be made to show the calculated product of voltage and current.
Meter Resolution:
  Voltage: 1mV (CV mode) or 10mV (CI mode)

SETTINGS MEMORIES

Main Output(s): Up to 50 set-ups per output can be saved and recalled via the keyboard or remote interfaces.
Parameters Stored: Range, Set volts, Set current, OVP, OCP.
Recall system: Settings are previewed onto the displays before being actioned.
Linked Mode: On triple output models when in Linked mode, a further set of 50 memories stores and recalls values
for both outputs simultaneously.
Auxiliary Output: Up to 10 voltage settings can be saved and recalled via the keyboard or remote interfaces.

ALARM OUTPUT

Isolated rear-panel open-collector output signal. User can select output to be activated for either OVP, OCP, Overtemperature or Sense miswiring, or for any of those four faults.

LINK & COPY - Triple Output Models

Each output can be controlled independently or can be linked. When linked, keyboard and jog wheel control operates on both outputs simultaneously.
Linked mode can be used to create tracking outputs, or for convenient series or parallel operation of the two outputs.
A Copy function is available which copies all of the settings for output 1 to output 2 (Range, Set volts, Set current, OVP, OCP).
Linked mode can also be used to store the settings for both outputs to a group of common memory stores when simultaneous recall is required.
(Note: Linked mode can be selected with differing voltage and current settings on the two outputs. However both outputs must be set to the same range.)
