- Product Name: Yokogawa E82EV751K4C040 Variable Frequency Drive (VFD) / Inverter Unit
- Product Brief: High‑performance industrial frequency converter belonging to Yokogawa E800 series, applied to AC motor speed regulation and energy‑saving control in industrial drive systems.
Detailed content
- Technical Specifications: Rated power: 7.5 kW; input voltage: 3‑phase 380‑480 V AC, 50/60 Hz; output voltage: 3‑phase 0‑480 V AC; control mode: V/F control, vector control without encoder.
- Functional Features: Built‑in PID closed‑loop regulation function; multi‑speed fixed‑frequency operation; overload protection, over‑voltage protection, over‑current protection, over‑temperature protection; RS‑485 communication interface supporting Modbus‑RTU protocol.
- Performance Parameters: Rated output current: 18 A; frequency adjustment range: 0.1‑400 Hz; acceleration/deceleration time adjustable within 0.01‑3600 s; efficiency ≥ 96% under rated working condition.
- Material Composition: Die‑cast aluminum alloy heat‑dissipation housing; IGBT power module core; high‑precision electrolytic capacitor; fire‑retardant engineering plastic control panel shell.
- Structural Characteristics: Compact vertical wall‑mount structure; built‑in cooling fan; detachable parameter setting panel; modular power circuit and control circuit layout.
- Working Principle: Converts 3‑phase industrial AC power to DC power via rectifier unit, then inverts DC power to variable‑frequency and variable‑voltage AC power through inverter module to realize AC motor stepless speed regulation.
- Advantage Highlights: High‑efficiency energy‑saving design; strong anti‑interference capability; wide voltage fluctuation adaptability; stable low‑speed torque output; easy parameter debugging and on‑site maintenance.
- Applicable Industries: Pump and fan drive, conveyor system, packaging machinery, textile machinery, water supply & drainage engineering, HVAC industrial control.
- Model Series: E800‑series general‑purpose high‑performance frequency converters of Yokogawa drive product line.
- Installation Requirements: Wall‑mounted inside ventilation‑good control cabinet; ambient temperature limited to ‑10 °C to +50 °C; reserved heat‑dissipation space around the unit; avoid direct sunlight exposure.
- Usage Precautions: Strictly match motor rated parameters when parameter setting; prohibited from overload long‑term operation; regular cleaning of cooling fan dust accumulation; ground connection must comply with industrial electrical safety standards.
