The FB3G190-85PS-90 is a voltage-specialized 190mm DC centrifugal fan delivering industrial-grade pressure (782Pa) and airflow (903m³/h) at 85VDC. Designed for systems with legacy or battery-based power (68–102VDC range), its glass-fiber-reinforced plastic impeller withstands 4300 RPM stress while drawing 2.1A for 175W output. Ideal for compact, high-resistance cooling.
Voltage-Optimized Performance
Engineered for 85VDC infrastructure—common in telecom backup systems or robotics—reducing voltage conversion losses. Tolerates ±20% voltage swings (68–102VDC).
Pressure-Optimized Efficiency
Matches higher-voltage models’ static pressure (782Pa) and airflow (903m³/h) while minimizing component stress in 85V ecosystems.
High-RPM Endurance
Glass-fiber impeller resists deformation at 4300 RPM, paired with ball bearings for >50,000 hours (L10) in 40°C environments.
Adaptive Electrical Protection
Integrated soft-start, reverse-polarity lockout, and thermal cutoffs—critical for 175W systems with higher current (2.1A).
Industrial Robotics: Cooling servo drives in 80V battery-powered arms.
Telecom Backup Units: Thermal management in 85VDC battery cabinets.
Military Electronics: Conformal-cooled radar/communication gear.
Floor Scrubbers/Mobile EVs: Ventilating confined battery compartments.
Legacy Machinery: Retrofitting older 80–100VDC industrial equipment.
Q1: Why choose 85VDC over standard 24V/48V?
A: For systems with existing 85V power rails (e.g., telecom batteries, robotics), eliminating DC-DC converters saves cost/space.
Q2: Does lower voltage reduce performance vs. 110V models?
A: No. Identical pressure/flow specs—just higher current (2.1A vs. 1.6A). Ensure wiring supports ≈180W load.
Q3: How to wire for long cable runs?
A: Use #18AWG or thicker. Follow color codes: red (+85V), yellow (PWM), white (FG), blue (GND).
