8. DIGITAL REMOTE CONTROL OPERATION

The PHV series is available with a wide range of optional digital control interfaces. The
interface must be specified at the time of ordering. The digital interface connector is located
on the rear panel of the unit (see Figure 2 and Figure 3).
Available interfaces are;
Contact the factory for the availability of other digital interface options.
The digital interface allows the user to program and readback output voltage and current,
turn ON/OFF the HV output, and ramp outputs at defined rates among other functions. The
digital interface supports up to 2000 programming commands per second.
To operate the unit in Remote Digital mode, set the LOCAL/REMOTE switch (see Item 18 in
Figure 2) to the REMOTE position, the LOCAL LED will extinguish. If the power supply
also features an Analog interface option, then set the DIGITAL/ANALOG switch (see Item
20 in Figure 2) to the DIGITAL position, the DIGITAL LED will illuminate. Commands can
now be sent to the Digital interface; the BUSY LED will flash to indicate the presence of
traffic on the interface.
The remote digital interface does not allow the user to set the OVP limit, this must be done
via the front panel as described in section 6.4.
All Digital interface programming commands and setup information can be found in the
specific interface manual. Details are on our web site at www.us.tdk-lambda.com/hp.
