Technical Specifications Model: BSD0750 Peak Braking Power: 750 kW DC‑bus Voltage Range: Matches supporting drive‑system voltage grade Control Interface: Compatible with ABB drive brake‑chopper control board driving signal Cooling Method: Forced air cooling Operating Temperature: 0 ℃ to +45 ℃ Storage Temperature: ‑40 ℃ to +70 ℃ Relative Humidity: 5‑95 %, non‑condensing Mounting Form: Cabinet wall‑mount or cabinet floor‑mount Protection Class: IP20 Certifications: CE
Functional Features High‑power IGBT components realize brake chopper switch function. Built‑in temperature sensor monitors operating temperature of power devices. Hardware over‑temperature protection triggers shutdown action once power‑device temperature exceeds limit value. Receives gate driving control signal from external brake‑chopper control board. Outputs over‑temperature fault feedback signal to drive main‑control system. Front‑panel LED status indicators display power‑unit running and fault conditions. Designed for heavy‑duty frequent‑braking industrial operating conditions.
Application Scenarios Large‑power crane, hoist and elevator multi‑motor drive‑system regenerative‑energy dissipation. Metallurgical rolling‑mill drive‑system DC‑bus over‑voltage suppression, spare‑part replacement projects.
Performance Parameters Peak Braking Capacity: 750 kW MTBF: 132000 hours Shock and Vibration: Conforms to IEC 60068‑2‑6 cabinet‑mount power‑equipment standard.
Installation Requirements Mount BSD0750 power unit on cabinet wall or cabinet floor according to mechanical installation drawing. Connect DC‑bus high‑voltage bus‑bar and brake‑resistor high‑power cables, tighten terminals to specified torque value. Connect multi‑pin control‑signal cable to matching control‑board interface. Complete protective‑earthing strictly following high‑power‑equipment grounding specifications. Keep air‑inlet and air‑outlet ventilation channels unobstructed for forced‑air cooling. Reserve sufficient maintenance operating space around power unit. Ambient operating temperature must stay within 0 ℃ ~ +45 ℃ without condensation.
