The 6623A-PCS/1000 enables test currents up to 1000 A to be realized and is supplied with one CS1000 current source chassis. The models 6623A-PCS/2000 and 6623A- PCS/3000 models provide for test currents up to 2000 and 3000 A and are supplied with two and three CS1000 current source chassis’s respectively.
1.3. OVERVIEW The Model 6623A-PCS/1000/2000/3000 Precision Current Sources are precision sources of both positive and negative currents up to a full scale of 3000 A. Figure 1-1 illustrates the instrument circuits in block diagram form with the connections to the load. A Model 66259 Control Unit provided with the system is programmable and allows for selection of range and polarity of the test current.

22U rack cabinet fully configured for 220 Volt, 50/60 Hz operation with a power requirement of two 30 A, 220 Volt circuits. The 6623A-PCS/1000 and 6623A-PCS/2000 models are assembled in the same 22U also fully configured for 220 Volt, 50/60 Hz operation with a power requirement of one 30 A, 220 Volt circuit.
Twelve 3/8-16 x 1-3/4” bolt (GPN 817-01205) see Note 2 Note 1: the number of 500 A connection cables (and associated hardware) is two, four, and six of each for the 6623A-PCS/1000, the 6623A-PCS/2000, and the 6623A-PCS/3000 respectively. Note 2: to be used with breakout plate.

Each power bar has two 15 A sections with circuit breaker protection. You should see the green 'POWER' indicator on each 15 A section of the power bars light up. Note that the 6623A-PCS/1000 and 6623A-PCS/2000 models will have only one power bar installed.
Section 2 2.2. INCOMING INSPECTION If no errors are displayed during power up of the individual CS1000 units then the 6623A-PCS Precision Current Source is ready to be used once the load is connected to either the main bus bar or one of the two lower current range terminals.

Section 2 Step 1) Connect a 0.01 ohm shunt standard to the 30 A terminals of the 6623A-PCS fly out panel at the top of the cabinet and connect the DVM to the potential terminals of the shunt standard. Use the 10 AWG, 30 A, test leads for the current connections. The SCW Lead supplied should be used for the potential terminal connections.

Section 2 Reference the DVM to verify that a potential of + 0.1000 volts ± 0.0005 volt is displayed. Note that the DVM should be suitably zeroed with no current being sourced. A negative test current can be selected by toggling the '-ve' function key at the top left of the main display window.
Section 2 2.3. 6623A-PCS/3000 FRONT PANEL There are no controls on the front panel of the 6623A-PCS/3000. Figure 2-4 : 6623A-PCS/3000 Front View OM6623A-PCS-1_2_3000-5-00 2-10 01 September 2021...
6 slave internal 150 A current source modules. A fault will cause the particular current source to be disconnected and will allow the remaining units to continue to function. Note that the 6623A-PCS/1000 and 6623A-PCS/2000 models will have only one or two CS1000 Current Source modules respectively. OM6623A-PCS-1_2_3000-5-00...
Section 2 2.4.1. Line Input Connectors The Line Input Connectors are a combination of a 3-prong AC standard male IEC connector, an ON/OFF switch. The CS1000’s have a 15 A circuit breaker as part of the Line Input Connector. The line input connectors accommodate nominal voltages of 208 to 240V.
Section 3 QUICK OPERATION GUIDE 3.1. OPERATION GUIDE This section contains information regarding the setup for the sourcing of positive or negative direct currents using the 6623A-PCS/3000 Precision Current Source. This guide is provided for manual control of the 6623A-PCS/3000 from the front panel of the 66259 Control Unit. The 66259 Operation Manual should be consulted to reference all the features of the control unit.
Section 3 3.1.2. Setup Limits and Precautions for 6623A-PCS/3000 See Figure 3-1 for the available compliance limits for various load current ranges. The current output is power limited to approximately 2000 watts per CS1000 unit with an approximate voltage compliance of 8 volts below 30 A and reducing to 1.5 volts above 150 A.
