PRODUCT DESCRIPTION
DSQC345C 3HAB8101-3 DC2 rectifier power module
ABB DSQC345C 3HAB8101-3 is the DC2 rectifier module used in documented S4C robot drive configurations. It forms the DC-link supply section feeding the separate axis drive units. ABB identifies DSQC345C, article 3HAB8101-3 and configuration DC2 together in the controller installation manual.
The documented rectifier ratings are 14.6 A rated current and 80 A maximum current, with a minimum DC-link voltage of 275 V. Maximum bleeder power is 15.3 kW, while rated bleeder power is 0.9 kW. These continuous and maximum values must be evaluated separately when checking the installed drive-system load.

SYSTEM INTEGRATION
Integrate DSQC345C 3HAB8101-3 DC2 rectifier power module
The S4C drive system separates the DC-link rectifier from the axis drive units and the serial measurement board. DSQC345C supplies the DC-link section; the axis drive electronics perform motor-current regulation. A rectifier replacement therefore does not substitute for an individual axis drive module.
Use the controller configuration record to identify the DC-link type. ABB lists DSQC345C and 3HAB8101-3 against configuration DC2. The same table assigns other configuration identifiers to DSQC345A, DSQC345B and DSQC345D, so a shared 3HAB8101 prefix does not establish interchangeability.
Check the drive-system demand against 14.6 A rated current and 80 A maximum current. The bleeder likewise has separate rated and maximum limits of 0.9 kW and 15.3 kW. The DC2 minimum-voltage figure is 275 V; the DC3 value in the same table must not be substituted for it.
Features:
- DC2 identity tied to article 3HAB8101-3
- Separate rated and maximum current budgets
- Distinct continuous and peak bleeder limits
The DSQC345C 3HAB8101-3 DC2 rectifier power module requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify DSQC345C 3HAB8101-3 DC2 rectifier power module
Record the complete 3HAB8101-3 label, DSQC345C designation and DC2 configuration before removal. Compare the existing power connections and cabinet arrangement with the installed controller documentation. The rectifier is a high-voltage assembly with stored capacitor energy; isolate the supply and verify that the DC link is discharged before handling.
ABB states that the drive system supervises internal errors and reports them through the controller to the teach pendant. Use the recorded fault information to distinguish a rectifier failure from a drive-unit, connection or supply problem. The manual directs replacement of a faulty rectifier rather than internal fault tracing in the operating environment.
After replacement, check the restored connections, retained DC2 configuration and controller fault indications before enabling motion. Where a control-program installation is also performed, the documented query-mode DC-link selection must match the actual unit. Keep the cabinet and external-axis drive arrangement consistent with the original system configuration.
Features:
- Stored-energy isolation before power connections are handled
- Teach-pendant fault records guide rectifier diagnosis
- DC-link configuration retained during controller restoration
The DSQC345C 3HAB8101-3 DC2 rectifier power module requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about DSQC345C 3HAB8101-3
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Which DC-link configuration identifies this DSQC345C rectifier?
ABB lists DSQC345C, article 3HAB8101-3 and configuration DC2 in the same DC-link identification table. -
Is 80 A the continuous current rating of DC2?
No. The published maximum current is 80 A; the rated current is 14.6 A. They are separate load limits. -
How do the two bleeder-power figures differ?
The rectifier table gives 15.3 kW maximum bleeder power and 0.9 kW rated bleeder power; the higher figure is not a continuous rating. -
Can the 370 V DC3 minimum be applied to DSQC345C?
No. ABB gives 275 V minimum for DSQC345C/DC2. The 370 V figure in the adjacent row applies to DSQC345D/DC3. -
Does the DC2 rectifier replace an individual axis drive?
No. The documented servo architecture separates the DC link, drive unit and motor. Match the fault and the actual failed assembly. -
Where does S4C report a rectifier or drive-system fault?
The drive system sends its supervised error through the controller for display on the teach pendant. ABB advises replacing a faulty rectifier rather than internal fault tracing in the operating environment. -
Which label details distinguish the requested DC2 spare?
Provide DSQC345C, 3HAB8101-3 and any suffix printed on the installed label, together with the S4C cabinet configuration and required quantity. -
Can the offered spare include the existing DC-link connectors?
Ask for the connectors and any other required items to be listed separately in the quotation for 3HAB8101-3; their inclusion should not be assumed.
