Modbus TCP/IP
Ethernet, Wi-FI, USB, HDMI

Optional modules

External 0 – 10 V Trigger input, Ground current monitoring, Float/gnd commanded by software, Additional interlocks, Freewheeling diode, air flow monitoring, Power lock, Active temperature monitoring and dynamic cooling control by temperature

Long term data storage

Alphα stores many parameters in a database. Those parameters can be displayed on charts, user can choose which parameters to display. All parameters data are stored from the first day of operation of the Alphα. Those can be downloaded from USB port.

Noise immunity

· Switching semiconductors are driven by means of an optical fiber digital transmitter, achieving the highest performance in terms of speed, bandwith, attenuation and noise immunity.
· Optic fiber drivers.
· The power supply uses a high frequency transformer designed to minimize the dispersed flow, preventing induced currents and noise generation.
