PRODUCT DESCRIPTION
The QPX750 is a single output laboratory power supply with a
maximum output power of 750 watts.
The P design provides voltages up to 80V, currents up
to 50A and flexible modes of operation (CC, CV, and CP) with
automatic crossover, while offering an exceedingly wide range
of operation, as detailed in the Pow curve.
This power supply achieves unusually low noise of <3mV rms at
full power and good transient response of <2ms.
This high feature Power Supply displays load power and load
impedance in addition to measurements of output voltage and
current. The load impedance calculation enables low resistance measurements to be made at high
currents by creating a four-terminal connection, using the remote sense terminals. Also provided is a
meter averaging function to dampen the load current - this can be selected in order to achieve more
accurate results when measuring rapidly varying loads.
This versatile power supply offers Analog and Digital interface for remote control and Test System
integration. Remote Communication is Standard with 2 interfaces: USB and LAN. An optional GPIB
interface is also available. Analog inputs provide remote control of the output volts and current while
Analog outputs provide monitoring of the output Voltage and current. Digital Opto isolated logic
signals provide an input that can control the output state on and off and an output confirms the
operating state; current limit, power limit, or any fault trip.
Housed in a ½ rack width, 3U high case with front input ventilation, an intelligent fan is used to
minimise cooling noise. It is suited to both bench-top and system applications.
The instrument has two ranges: 50V or 80V. The unit is set on the SELV setting of 50V to reduce the
risk of hazardous voltages and simplifying compliance with the safety requirements.
NOTE
By default, the range that allows a maximum of 80V is
disabled. To enable the 80V range - the user must manually
select this range. Before confirming this choice, a warning
will appear to inform of the risk.
