FUNCTIONAL DESCRIPTION:

DS200PCCAG8A is a Power Connect Card manufactured and designed by General Electric as part of the EX2000 Series used in GE Excitation Control Systems. The DS200PCCA Power Connect Card (PCCA) acts as an interface between the drive's control circuitry and the SCR power bridge. It utilizes pulse transformers to supply gate drives to the SCR bridge. For low-to-medium horsepower controllers, the PCCA includes snubber circuits to manage spikes across the AC lines, DC bus, and gate drivers. In higher horsepower controllers, these snubber circuits may be removed from the PCCA and placed elsewhere in the system.

BOARD GROUPS:

The PCCA board has ten group numbers. The group number used in a system is determined by the system voltage, frame size, and whether the system uses regenerative or non-regenerative power conversion. Table 1 summarizes the applications of the various PCCA board group numbers. The armature voltage scaling depends on which PCCA board group number is used:

• G1, G7, G9 – Regenerative, 240 – 630 volts
• G2, G8, G10 – Non-regenerative, 240 – 700 volts

The PCCA board has four wire jumpers, designated JP1, JP2, WP3, and WP4 that select system voltage and determine snubber capacitor connections.

CONFIGURABLE JUMPERS (JP and WP):

The PCCA board has four wire jumpers, designated JP1, JP2, WP3, and WP4. Jumpers JP1 and JP2 should be connected to the correct stab terminals (P3 through P10), based on the card group number and system voltage. Jumpers WP3 and WP4 are used to link stab terminals P2A to P2B and P1A to P1B, respectively. These jumpers determine whether the PCCA snubber capacitors are connected to the same point on the power bridge as the voltage feedback channel.

FREQUENTLY ASKED QUESTIONS:

What do jumpers JP1 and JP2 do?

Jumpers JP1 and JP2 connect to stab terminals P3 through P10, as determined by the card group number and system voltage. They ensure proper configuration of the power connect card for optimal performance.

What is the role of jumpers WP3 and WP4?

Jumpers WP3 and WP4 connect stab terminals P2A to P2B and P1A to P1B, respectively. These jumpers are used to select whether the PCCA snubber capacitors are connected to the same point on the power bridge as the voltage feedback channel.

What are snubber circuits, and why are they important?

Snubber circuits are used to manage voltage spikes across the AC lines, DC bus, and gate drivers. For lower horsepower controllers, these circuits are included on the PCCA board to protect against electrical disturbances.
