The PSR1A is a single channel, digital power supply, display and controller. This single channel version can control one mass flow controller (MFC) or mass flow meter (MFM). The PSR1A can operate either ±15 VDC MFC/MFMs or singlesided 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 PSR1A 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.
