Xantrex Technology XDL 35-5TP Manuale Utente
Introduction
Unmatched Precision, Unrivalled Performance
The XDL series represents the ‘next generation’ of laboratory power supplies offering an
unparalleled level of precision.
unparalleled level of precision.
Voltage and current are controlled using 16 bit DACs enabling voltages to be set to 1mV
resolution even at full output. Indeed, the accuracy is sufficient for the PSU to be used as a
calibration source for some hand-held DMMs.

The XDL series uses pure linear technology and offers unrivalled performance in terms of
regulation, output noise and dynamics. Line and load regulation are close to the limit of
measurement. Output noise is less than 350µV rms in CV mode and down to 20µA rms in CI
mode. Recovery time from transient current pulses is better than 50µs.

The XDL series provides full remote sense capability via dedicated sense terminals. Remote

Multiple Ranges for Greater Flexibility
The XDL series provides multiple ranges for increased current capability at lower voltages. The
main range offers 0 to 35 volts at up to 3 Amps. The higher current range provides up to 5 Amps
for voltages up to 15V. A further low current range provides enhanced current setting and
measurement resolution of 0·1mA.

Fast, Simple and Safe to use
The user interface of the XDL series has been carefully designed to provide rapid control whilst
guarding against any possibility of error.
guarding against any possibility of error.
Voltage and current setting can be performed either by direct numeric entry or, for applications
where the voltage or current must be gradually changed, by using the quasi-analogue Jog
control.

To enable the current limit to be set before connecting the load, the limit setting is displayed when
the output is off. Pressing the View Limits key at any time provides a temporary display of the limit
values allowing precise adjustment to also be made with the output on.

Setting Memories for Added Convenience
The XDL series provides storage of up to 10 power supply sets-ups in non-volatile memory for
each main output, plus a further 10 set-ups for linked mode operation. Upon mains switch-off, the
set-up of the PSU is saved and is automatically restored at switch-on.

OVP and OCP Trips with 'Alarm' Output
The XDL series provides fully adjustable over-voltage and over-current trips which can be used
both as a fail-safe against accidental mis-setting and as a protection against inappropriate load
conditions. In addition to turning the output off, a trip condition switches the rear panel alarm
signal enabling other equipment to be controlled.

For complete protection of the power supply, the trip will also be operated by over-temperature or
excess voltage on the sense terminals.
