MSC2.5PN7.5 Electrostatic Chuck Power Supply

The MSC2.5PN7.5 is a bipolar reversible power supply specifically designed for electrostatic chuck clamping applications. Two 0 to 2500 volt @ 7.5 watt reversible outputs that are of opposite polarity are provided on the two high voltage output connectors. Front panel controls via programming buttons and an OLED display allow local operation and control of the unit. The RS-232/RS-485/Ethernet digital interface allows for simple OEM integration into complex system designs.

Not designed to withstand continuous arcing.

Auto-Toggle/De-Chucking Function:

This unit has both a manual and a customer configurable automatic toggle function (degauss/de-chuck)

Communication:

The unit can be operated locally from the front panel. It can also be controlled through the RS-232/RS-485 serial interface, or Ethernet. The serial interface can be configured via the front panel to either RS-232 or RS-485. The unit is shipped from the factory set to RS-232. 9600 baud, no parity, no handshake or flow control. Note: When Ethernet is connected to the LAN port, Serial comms is disabled.

Front Panel Indicators:

The unit has a 20 character by 2 line back lit OLED display and a high voltage status LED. Configuration and setting of various parameters can be accomplished via push button switches. The OLED will power down after five minutes and is reactivated by pressing any button. The red LED indicator illuminates when high voltage is being produced. When the unit is shutdown due to a fault the LED will flash at a 1 Hertz rate until the fault is cleared.

Front Panel Controls:

The unit has front panel buttons for local control.
