The PSR4A is a four channel, digital power supply, display and controller. This four channel version can control four mass flow controllers (MFCs) or mass flow meters (MFMs). The PSR4A can operate either ±15 VDC MFC/MFMs or single-sided 15 VDC.
The large 8 x 20 display, with intensity control, provides the user with a clear view of MFC/MFM status. The readout is provided with hardware for panel mounting or as a table top display.
The PSR4A has RS-232 serial port communication for remote control, data logging and remote alarms. Gauge factor scaling allows the user to adapt to different gases for the MFC/MFM.
