Model: Kepco SN488-121     Condition: Used

SN are single- or dual-channel digital to analog converters for use with Kepco¿s analog-programmable power supplies.  They provide an optically isolated listen-only control channel that provides a precise 0-10V analog output to drive Kepco¿s JQE, ATE and similar operationally controlled power supplies.

They are available in decimal format (3-digit BCD), or in hexadecimal format (12-bit binary). A single-channel instrument can be converted in the field to a dual-channel model by plugging in auxiliary boards SN 603 or SN 612.

  • The SN 488 implements the AH1 acceptor handshake and L1 listener, plus listener-only functions of the IEEE 488 protocol.
  • The SN Series incorporate optical isolation (up to 1000 Volts d-c), so they may be used to control floating power supplies.
  • The SN 488 offers a choice of single- or dual-channel operation. Each channel is completely isolated from the other so that they can be used to drive independent instruments or two functions of the same instrument, (e.g., voltage setting and current limiting in an ATE power supply). Both channels obtain their data through a single input connector. Addressing is  used to select which channel responds.

  • Both single- and dual-channel models are stocked; however, a single channel model can be converted to a dual-channel model by the installation of either a Model SN 612 (binary) or a Model SN 603 (BCD) field installable card.

  • The SN 488 provides a means of controlling positive or negative polarity. This feature is useful when the SN 488 controls a bipolar power supply such as the Kepco Series BOP.

  • The SN 488 provides a means of controlling range over a 10:1 ratio. This is accomplished by a programmable attenuator. The ¿high¿ range provides a 0 to }10V analog output; the ¿low¿ range provides a 0 to }1V analog output.
