General description

SIP POWER is the power supply that controls the ion pump (IP) of NEXTorr family. NEXTorr
pumps combine in a very compact and unique design Non Evaporable Getter (NEG) and ion pump
technologies.
SIP POWER can be supplied with alphanumeric display or without display.
The controller version without display is equipped with RS485 interface and 2 status LEDs.
For both solutions, the controller case is a sub-rack 3U 14TE 230mm deep.
Both solutions can be equipped with ETHERNET (to remote control the device) and USB (to record
the device parameters on a USB flash memory) data interfaces, but devices without these
interfaces are also available.
The device is powered by external source of 24Vdc and provides voltage values between 600V
and 6kV to the ion pump.
SIP POWER has an autoranging internal system for measuring the output current.
The current value is shown on the display (or provided through the serial communication in version
without display). The current value is also provided through the ETHERNET communication in nA
units. The serial communication and the ETHERNET communication can also provide the voltage
output value. The current value and the voltage output value are also automatically stored in USB
flash memory if it is connected in its slot.
The SIP POWER has two security signals to provide high voltage values to the ion pump:
the SAFETY connector and the INTERLOCK signal.
A SAFETY pin connector allows managing the supply of the high voltage to the ion pump in total
security. The INTERLOCK contact allows to shut down the high voltage to the ion pump with an
external alarm signal.
SIP POWER has 3 optional data interfaces:
* ETHERNET (to remote control the device)
* USB (to record the device parameters on a USB flash memory),
* RS485 (only available for the version without display).
The device has also a special interface with the DB15 connector compatible with NIOPS devices of
NEXTorr pumps.

Remote and multi Control

Dedicated software is provided to remotely control the SIP POWER through the ETHERNET
connection. The software allows to control several SIP POWER units at the same time.
All functions and parameters can be easily controlled through the software.
Software allows controlling a single unit or more units at the same time.
Local and remote control are possible contemporarily.
This software is available for Windows and for Linux PCs.
For SIP POWER equipped with RS485 interface a different dedicated software is available (just for
one unit at a time). Serial communication protocol via RS485 is MODBUS RTU (for more details
