Specification
General specifications apply for the temperature range 5°C to 40°C. Accuracy specifications apply
for the temperature range 18°C to 28°C after 1 hour warm-up with no load and calibration at 23°C.
Typical specifications are determined by design and are not guaranteed.

0V to 30V/1mA to 3000mA; 0V to 30V/0.1mA to 500mA (each 30V output);
0V to 30V/2mA to 6000mA; 0V to 30V/0.2mA to 1000mA (parallel mode).
& 0V to 6V/1mA to 8000mA; 0V to 6V/0.1mA to 800mA (PL303QMT O/P3)
Note: In manual operation, actual maxima for voltage and current are typically 1% greater than the
figures given above.
Voltage Setting:
By coarse and fine controls.
Current Setting:
By single logarithmic control.
Configuration Selection:
(PL303QMD & QMT only)
Independent, True parallel, Isolated Tracking & Isolated Ratio Tracking
modes via front panel rotary switch.
Voltage Span Control
(V-Span)
The voltage adjustment range can be controlled by digital setting of the end-
stop values of the coarse voltage control to any desired values.
The range for Vmax is 0.1V to 6V/15V/30V/60V depending on model.
The range for Vmin is 0 to (Vmax – 0.1V).
Settings Lock
(S-Lock)
Voltage and current settings can be locked by a single button press.
Lock accuracy is equal to meter accuracy (see Meter Specification)
Output Mode: Constant voltage or constant current with automatic cross-over.
CC indicator lit in constant current mode.
Output Switch: Electronic, non-isolating.
Preset voltage and current limit displayed when Output is off.
Output rise time with no load <15ms.
Output Terminals: Universal 4mm safety binding posts on 19mm (0·75”) spacing for Output;
screwless terminals for Sense.
Transient Response:
<50µs to within 50mV of set level for a 5% to 95% load change.
Voltage Programming
Speed (PL-P models):
Maximum time required for output to settle within 1% of its total excursion (for
resistive load). Excludes command processing time.
