comprar Reemplazo de la unidad del controlador de excavadora Ec200d Ec380d Ec480d

The technical parameters of the controller unit are fully matched to EC200D, EC380D, and EC480D specifications:

Tensión de funcionamiento: CC 24 V (standard for Volvo heavy-duty excavators), con protección contra sobretensión (máx. 32 V) y protección contra subtensión (mín. 18V) to withstand power fluctuations in harsh work environments.
Tiempo de respuesta de la señal: ≤18ms (EC200D/EC380D) / ≤15 ms (EC480D), ensuring instant parameter adjustment to meet the high-response demands of heavy-load operations for EC480D.
chip de procesamiento: MCU de 32 bits de grado industrial (EC200D: 1MB de memoria flash; EC380D/EC480D: 2MB de memoria flash) to support complex data processing for heavy-duty hydraulic and engine control.
Protocolo de comunicación: Puede 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 minutos).
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 (inactivo) / ≤30W (carga completa) for EC200D; ≤15W (inactivo) / ≤35W (carga completa) for EC380D/EC480D, minimizing burden on the excavator’s power system.
