Measurement and control
All TTi laboratory power supplies offer high accuracy
digital meters together with high resolution controls and dc
output switches.
Standard models
Standard models, such as the EL and EX series, incorporate
three digit meters for both voltage and current. This
provides a level of accuracy and resolution sufficient for
many purposes. Separate coarse and
fine voltage controls allow rapid and precise adjustment
whilst a semi-logarithmic current control provides increased
setting resolution at lower currents.
Precision models Precision
models, such as the EX-R, PL, TS, TSX and CPX series, offer
a higher level of precision by incorporating four digit
meters and remote sense terminals.
Four digit meters provide higher resolution and accuracy.
Remote sense enables the power supply to regulate the voltage
directly at the load thus eliminating the effect of
connection lead resistance. High
precision digital control models
The QL series offer an unprecedented level of precision by
incorporating 16-bit digital control and five digit metering
with a resolution of 1mV.
This is matched with 0.1mA current
resolution and remote sense terminals.
Voltage and current can be set directly from a numeric
keyboard or can be set in quasi-analog mode using a rotary
encoder. A similar control system is used on the QPX
series.. |
