Specification - Aim TTi PLH Serie Instructions

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.

Note: In manual operation, actual maxima for voltage and current are typically 1% greater than the
figures given above, with the exception that the PLH250 cannot be set above 250.0V.

Note: The above times are examples. The settling time for a particular voltage change is determined
by the current available to charge the internal output capacitance (22
For large voltage steps and low current limit settings the settling times can be significantly longer.
Ripple and Noise*
(20MHz bandwidth):
*Specification applies for manual and digital interface operation only. Under analogue remote control
noise is a little worse but will typically still meet the limits given.

0V to 120V/0.1mA to 750mA; 0V to 120V/0.01mA to 75mA
0V to 250V/0.1mA to 375mA; 0V to 250V/0.01mA to 75mA
By coarse and fine controls.
By single logarithmic control.
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 120V/250V depending on model.
The range for Vmin is 0 to (Vmax – 0.1V).
Voltage and current settings can be locked by a single button press.
Lock accuracy is equal to meter accuracy (see Meter Specification)
Constant voltage or constant current with automatic cross-over.
CC indicator lit in constant current mode.
Electronic, non-isolating.
Preset voltage and current limit displayed when Output is off.
Output rise time with no load <20ms.
Front panel: Universal 4mm safety binding posts on 19mm (0·75") spacing
for Output; screwless terminals for Sense.
Rear Panel: (PLH-P only) Screwless terminals for Output; no Sense.
