Product Overview

TVD 1.3‑08‑03 is 7.5 kW common‑bus power‑supply unit for legacy Indramat modular servo‑drive system. It rectifies three‑phase mains power to stable 320 V DC‑bus to supply multiple servo axis‑modules, and provides regulated 24 V / ±15 V auxiliary power for drive‑control electronics. Integrated brake‑bleeder resistor dissipates motor‑regenerated energy during deceleration cycles. Widely deployed for metal‑working machine‑tools, printing machinery and packaging‑production‑lines. Discontinued legacy drive spare hardware; surplus and refurbished tested units for machine‑tool cabinet overhaul and maintenance‑projects.

Application Notes

‑ Respect three‑phase mains‑phase‑sequence requirement during power‑on commissioning. ‑ Calculate total DC‑bus load when adding axis‑modules to avoid over‑rating. ‑ Verify brake‑bleeder thermal condition under high‑regeneration‑cycle operation. ‑ Typical deployment: Indramat multi‑axis‑drive power‑supply‑unit spare‑part stocking.
