3458A Multimeter - DVM - Precision Voltage Measurement

Krohn-Hite - Model 523 Precision DC Source

Optional Local Control Board (LCB) which features Current Loop Tuning.
​
The Local Control Board connects to the Local Control connector on the PCRC front panel using a standard DB37 M-M cable.

Features 

• BNC connectors for current loop tuning.

When used with an external signal generator and decade box, more precise tuning of the error amplifier is possible.

• Allows for Local Control of the Power Supply for diagnostic purposes.

Switch S2 when enabled provides for local control.  An LED indicates when local control is active.

• 25 LEDs for status checking.

Yellow LEDS generally indicate status and modes, Red LEDS indicate faults, and the Green LED indicates a system ready condition.

• 23 Test points for measuring analog voltages.

Test points allow for monitoring of controller supply and reference voltages, internal temperature readings, DAC outputs, and other PCRC outputs.

• Provides a reset for the controller processor.

Momentary contact switch S7 allows for a reset of the PCRC processor.

• Local control potentiometer provides a 0 to 10V local control reference.

A jumper switch allows for a 0 to -10V reference for use with a reversing switch for polarity reversing.

4 Quadrant Bipolar Power Supply
MCOR - Magnet Corrector Power Supply Modules

Overview​

The MCOR Magnet Correction Power Supply Modules are capable of providing precision Bi-Polar output currents with models ranging from ± 1 Amps output up to ± 30 Amps output. Eight MCOR models (see Table I) are currently available .  The modular architecture  allows for up to 16 MCOR (MCOR Models 12 and below) or eight MCOR Model 30 modules, to plug into one 6U crate.  The crate also houses a single EMCOR Controller (Ethernet MCOR Controller module) that can control all MCOR modules residing in the crate.  The EMCOR Controller Module, in addition to controlling the outputs of all of the MCOR modules in the crate, also monitors feedback and monitor currents of the MCOR outputs, as well as ripple and fault conditions. The EMCOR controller is a new product that allows for Ethernet and USB Interface connections.  This new controller replaces the obsolete C4 Interface module.  To find out more information about the models of MCOR modules available, use the links below.

The Ethernet MCOR (EMCOR) Controller module was designed to be used in conjunction with an MCOR Crate  and up to 16 MCOR Power Supply modules as the Controller assembly for all 16 MCOR modules. The EMCOR module comes equipped with its own CPU module. Ethernet and USB interface connections are available and can be used to control the output level of all MCOR modules, as well as monitor and feedback current, ripple, and fault status of all 16 channels simultaneously. Current and Ripple measurements to the EMCOR module are provided by each of the MCOR modules using indepepndent readings (Monitor and Feedback readings) in the form of an analog voltage.  The ADCs of the EMCOR module digitizes and stores the data making it easily accessible for monitoring purposes.
The EMCOR module has the ability to control all different MCOR module types in the same crate.  Power for the EMCOR module is supplied by the crate. A single Bulk Power Supply supplies the power outputs for all MCOR modules residing in the crate.
The EMCOR Controller module replaces the C4 Interface Module, which is now considered obsolete.
