The DIGITEL
™
1500 is an ion pump power supply and system
control. It accommodates ion pump sizes from 120 Lis. The
high-voltage design provides ample current for larger ion pumps, but
will limit power applied to a smaller ion pump. The AUTORUN
feature determines optimum starting and running conditions for the
pump size selected and then starts and monitors the pump without
operator assistance. This feature also provides protection for the pump
in case of overload conditions, power failures, ion pump malfunctions,
or system malfunctions. The DIGITEL operates on 208/230 Vac,
50 or 60 Hz.
The DIGITEL is a programmable, microprocessor-based unit. The
front panel digital display (shown below) provides direct readout of
ion pump voltage, current, and pressure (torr or pascal). Ranging is
automatic within the selected display mode. A
Rate-of-Rise
bargraph
indicates the pressure trend in the system.
The keyboard controls all functions except main power and high
voltage and includes optional features that allow you to customize the
unit to a particular system.

Ion Pump System Controller
A setpoint option provides two programmable setpoints, a dedicated
setpoint if voltage goes below 2000V, and two remote inputs (standby
and operate). The setpoint/bakeout option provides control over a
complete system bakeout sequence with its own setpoint. A computer
interface option allows information exchange with a host computer for
remote control and log reports. Two analog outputs are provided for
use with a data acquisition device or for leak detection.
