The technical parameters of the controller unit are fully matched to EC200D, EC380D, and EC480D specifications:
- Betriebsspannung: DC 24V (standard for Volvo heavy-duty excavators), mit Überspannungsschutz (max. 32V) und Unterspannungsschutz (min. 18V) to withstand power fluctuations in harsh work environments.
- Signalreaktionszeit: ≤18ms (EC200D/EC380D) / ≤15ms (EC480D), ensuring instant parameter adjustment to meet the high-response demands of heavy-load operations for EC480D.
- Verarbeitungschip: 32-Bit-MCU in Industriequalität (EC200D: 1MB-Flash-Speicher; EC380D/EC480D: 2MB-Flash-Speicher) to support complex data processing for heavy-duty hydraulic and engine control.
- Kommunikationsprotokoll: KÖNNEN 2.0B (Volvo standard for excavator electronic systems), fully compatible with the original communication frameworks of EC200D/EC380D/EC480D.
- Protection rating: IP67 (EC200D) / IP68 (EC380D/EC480D)—the higher IP68 rating for EC380D/EC480D ensures dustproof and waterproof performance even in deep mud or water immersion (up to 1m for 30 Min).
- Working temperature range: -40℃ ~ +85℃ (EC200D) / -45℃ ~ +90℃ (EC380D/EC480D), adapting to extreme temperatures in mining and high-altitude regions for heavy-duty models.
- Power consumption: ≤12W (Leerlauf) / ≤30W (Volllast) for EC200D; ≤15W (Leerlauf) / ≤35W (Volllast) for EC380D/EC480D, minimizing burden on the excavator’s power system.
