General Information
The DIGITEL™ Multiple Pump Controller (MPCe) and Large Pump Controller (LPCe) are ion pump power supply
controllers.
The DIGITEL MPCe is designed to operate up to two ion pumps independently or up to four simultaneously along
with and a titanium sublimation pump (TSP) or non-evaporable getter (NEG) pump.
The DIGITEL LPCe can operate a single ion pump independently or up to four ion pumps simultaneously
Both units can accommodate pump sizes from 10 l/s and up to 1200 l/s.
They are microprocessor-based controllers containing a metering circuit, 8 process set points, and support
standard serial communications. The front panel display provides direct readout of the ion pump voltage, current,
or pressure.
Features
High Voltage Modules
The DIGITEL MPCe is available with up to two high-voltage (HV) modules and the DIGITEL LPCe is available
with one medium high voltage module:
•
The medium HV module has a starting capacity of 200W, 100 mA. It is intended to operate pumps from
10 l/s to 200 l/s and can be used on larger pumps if they are already under high vacuum.
•
The large HV module has a starting capacity of 1000W, 500 mA. It is intended for pumps from 160 l/s to
1200 l/s.
HV modules are transformer design with low noise, high reliability, and pump overload protection. The output
voltage can be configured to ±7000 or ±5600 VDC for operating different pumps. For economical operation of
more than one pump, optional high-voltage output connectors can be added. Output connectors are configurable
between SHV 10kV and Fisher Style connectors.
Serial Port
The DIGITEL MPCe and LPCe can be interfaced and remotely controlled by a computer. All commands entered
from the touch screen can be performed from the serial port.
Analog Outputs
Two analog outputs are provided independently for each HV module to connect the controller to data-acquisition
devices (for a total of 4 analog ouputs). One outputs provide a 0 to 10 volt signal with a scale factor of 1 volt per
1000V output voltage (V
MON
). The other output is programmable based on current or pressure.
