Specifications

This is the DC power supply for
every engineer’s or electronic
technician’s lab bench. It has two
tracking 25 V outputs, which are
together referenced to a floating
common, and an isolated 6 volt
output. It is easy to control from
the front panel, or with industry
standard SCPI commands via the
GPIBorRS232.VXIPlug&Play
drivers are available to further
simplify computer control. Up to
3 complete states can be stored for
later recall. The low noise, excellent
regulation, and built-in voltmeter/
ammeter make this reliable power
supply well suited for the needs
of the R&D lab.
