The SAES NEG controller is designed to provide the specific power and heating requirements required for getter pump activation. The activation parameters can be adjusted to actively monitor the temperature of the pump equipped with thermocouples. The controller can be operated via the IO interface or remotely via Ethernet or RS232 interface (RS232 RS485 on the D-1000 2000 controller). A USB port is provided for easy data logging and can also be used as an interlocking device.
Ultra- and extremely high vacuum pressures can be achieved and maintained using an getter pump alone or in an ion pump. The single-channel SAES Geters NEG power supply microcontroller is designed for the lower power requirements of the SAES D400 getter pump, while the larger NEG power controller provides the required power for the D1000 or D2000 getter pump.
Features:
Activate the getter pump with an adjustable starting temperature.
Selectable voltages are suitable for getter activation and regulation.
Adjustable output voltage, program ramp time, and shutdown time.
The temperature of the pump cell is monitored by the getter pump.
NEG power microcontrollers have either a local IO interface or a remote RS232 or Ethernet interface.
The NEG controller has a touchscreen display, as well as a local I-O, remote RS232 RS485 or Ethernet interface.
Shipped without a power cord and needs to be ordered separately.

How it works
The getter pump controller is a device used to control the ion pump, and its main principle is to control and regulate the ion pump by adjusting the electrode voltage, current and other parameters according to the working state of the ion pump and the needs of the vacuum system.
Here's a general overview of how a getter pump controller works:
Sensor Detection: Controllers are usually equipped with a variety of sensors to monitor the status of the vacuum system and the operation of the ion pump. These sensors can detect parameters such as vacuum, electrode temperature, current, etc.
Feedback control: The controller monitors and controls the working status of the ion pump in real time according to the feedback information of the sensor. For example, if a vacuum level is detected below a set value, the controller adjusts the electrode voltage or current based on the feedback signal to increase the pumping capacity of the ion pump.
Closed-loop control: The controller usually adopts a closed-loop control system, that is, it adjusts according to the actual situation fed back by the sensor, so that the working state of the ion pump is stable within the preset range. This control ensures the stability and reliability of the vacuum system.
Protection Functions: The controller also has various protection functions to protect the ion pump and vacuum system from adverse conditions such as overload, overheating, overpressure, etc. For example, when the ion pump is overloaded or the temperature is too high, the controller will automatically stop working to prevent damage.
User interface: The controller is usually equipped with a user interface for setting working parameters, monitoring the working status and displaying alarm information, etc. The user can adjust the working mode and parameters of the ion pump through the interface operation.
