The MAT Power Module can also be directly controlled via the keypad of the MBT Series (“G” Option) Power Supply via the IEEE 1118 bus. An important feature of the MAT Series Power Module is the overvoltage and overcurrent pro- tection circuits.

NOTE: Do not move the wires connected to the barrier strip, they are properly placed for both 115 Va-c and 230 Va-c operation. Figure 2-3A shows the barrier terminal block set to 115 Va-c operation. Remove the jump- ers on the barrier strip connecting terminals 2 to 3, and terminals 4 to 5. Place a jumper between terminals 3 and 4.
National and international safety standards set procedures for the grounding of a metal cover and chassis of an instrument connected to an ac power source. The MAT Power Module is supplied with an ac female plug (MS3106A16-10S, Kepco P/N 143- 0331), that mates with a chassis mounted male receptacle (MS3102A16-10P. Kepco P/N 142- 0268).

FIGURE 2-4. VARIATION OF OUTPUT IMPEDANCE WITH FREQUENCY FOR A VOLTAGE SOURCE AND A CURRENT SOURCE A practical model for a voltage stabilized Power Module includes a series inductance represent- ing dc and low frequency source impedance. Load leads should have minimum voltage drops (error sensing is discussed below) and minimum inductance (error sensing does not compen- sate for this).
2.6.5 LOAD CONNECTION WITH REMOTE ERROR SENSING The MAT series of Power Modules can operate with sensing external to the Module. Sensing should be with a twisted wire pair to reduce noise. The sensing wires must be connected as fol- lows: Output terminal 1 to Sense Terminal 1 and Output Terminal 2 to Sense Terminal 2, each at the load (see Figure 2-6).
In this procedure the MAT Power Module Control Bus address is 3, (it is set at the factory to 3). Connect the Kepco Power Module Controller and the MAT Power Module (following check-out uses a MAT Power Module Model 100-10 as an example) to the Control Bus. Connect the Host Computer and the Power Module Controller to the IEEE 488 GPIB.

Power for the microcomputer board of the TMA 4882-27 Power Module Controller is provided by a wide range input Power Supply, Kepco Model MRW 150KV. The AC input voltage can range from 95 Volts AC to 264 Volts AC, thereby eliminating the need for an input voltage selector.
command causes noncatastrophic error messages to be stacked in memory until interrogated by a Status command. AUTOMATIC (TRACKING) CONTROL OF THE CROWBAR LEVEL MAT Power Modules have Overvoltage and Overcurrent Tracking Amplifiers. These amplifiers will cause a crowbar flag, send a catastrophic error to the Power Module Controller and shut the module down if the output goes out of tolerance.
REMOTE PROGRAMMING 3.6.1 GENERAL Kepco MAT Power Supplies are programmed over a control bus using either SCPI (Standard Commands for Programmable Instruments) or CIIL (Control Interface Intermediate Language) commands. SCPI and CIIL provide a common language conforming to IEEE488.2 for instru- ments used in an automatic test system.
For the complete command set, and detailed SCPI programming information, consult the Technical Manual for the applicable controller (the SCPI command sets among Kepco con- trollers are slightly different). See PAR.3.2 to establish the MAT power supply Control Bus (BIT- BUS) address.

3.6.3 CIIL PROGRAMMING The CIIL command language is used on early models of Kepco power supplies and controllers. The command functions are included here for compatibility with other equipment programmed with CIIL commands. The CIIL command set for the MAT Power Supply is defined and explained in Appendix A.

Syntax: INX VOLT (initiate voltage reading) INX CURR (initiate current reading) Function: Commences a data acquisition process in accordance with the preceding FNC command. Description: The response to the INX command is a dynamic time-out value, unless a catastrophic error condition exists, in which case an error message will be returned.
VOLT or CURR value so that the power supply's polarity may be selected. In the case of Kepco's MAT power supplies, the two related Op Codes, SRX and SRN are functionally identical to the SET command, since there is only one range, 0 - maximum. The commands are included only for compatibility.
OPN, CLS Syntax: OPN :CHnn CLS :CHnn Function: These commands are used to connect or disconnect the power supply from the load (effective for MR and MGR options only). Description: Disconnects the load from the power supply specified by the operand. Connects the load to the power supply specified by the operand.

Syntax: Function: Causes power supply to return operating status to controller. Description: This operator commands the power supply to report its present operating status. Status is reported in the form of a message (character string) as defined below. Any catastrophic error conditions (indicated by * in the table below) which exist will be reported, until the error condition is corrected.
