QPX1200L 1.2kW PowerFlex dc power supply - 60V, 50A max.
Unrivalled Flexibility
The QPX1200L offers users a level of flexibility that can not be
achieved with conventional laboratory power supplies.
With a current capability of 20 amps at the maximum output of
60 volts, its PowerFlex design offers increasing output current
with reducing output voltage. The QPX1200L can therefore per-
form the task of many different power supplies.
Example voltage/current combinations include 60V/20A,
48V/25A, 37.5V/30A, 26V/40A, and 20V/50A.
High precision
With setting controlled by an instrumentation quality 16 bit DAC,
the QPX1200L offers high accuracy and stability.
Low noise
Mixed mode regulation with a linear output stage gives the
QPX1200L exceptionally low output noise for a unit of this
power, and ensures good transient response.
Bench or rack mounting
Unlike most higher power laboratory PSUs, the QPX1200L is
equally suited to bench or rack-mount applications.
Output and sense terminals are provided on both the front and
rear panels. The case has integral tilt feet, and a 3U rack mount
is available as an option.
A wide range of interfaces
The QPX1200 has analog, RS-232, USB and LAN interfaces as
standard, the latter conforming with the LXI standard.
An optional GPIB interface can be specified at time of order.

The maximum current at
any voltage settings is
limited by the power
envelope which is set to
give 20A at 60V rising to
50A at 20V under all ac
supply conditions.
At lower output voltages
the power is restricted by
the 50 amps current
maximum.
