Description
Delta PFC0648SE-00P8 (also known as PFC0648SE00P8) is a high-static-pressure DC axial cooling fan engineered for extreme-density thermal environments within the DC Axial Fans category. Designed in a compact 60 x 60 x 38 mm (2.36 x 2.36 x 1.50 in) tubeaxial form factor, the unit operates across a wide 36.0 to 60.0 VDC input range with a nominal rating of 48 VDC, consuming 24.96 W (0.52 A nominal, 0.70 A max safety rating) at a peak rotational velocity of 17,000 RPM. Constructed with durable UL94V-0 flame-retardant plastic housing and impeller, the assembly integrates a precision dual ball bearing system that ensures reliable S1 continuous duty across industrial temperature profiles. Electrical interfacing is handled through a 4-wire lead assembly supporting PWM variable speed control and a tachometer speed sensor, paired with locked-rotor and polarity protection.
Key Features
- Aerodynamic & Electrical Ratings: Operates at 48 VDC nominal (36.0–60.0 VDC operating range) drawing 0.52 A (0.70 A max) and 24.96 W (33.60 W max), delivering 65.35 CFM (1.851 m³/min) airflow and 3.503 in H₂O (872.6 Pa) static pressure at 17,000 RPM.
- High-Pressure Mechanical Geometry: Compact 60 x 60 x 38 mm square tubeaxial profile optimized for severe system impedance, with standard 50.0 mm mounting hole spacing.
- Motor Architecture & Insulation: Brushless DC motor architecture rated for UL Class A insulation, featuring 10 MΩ minimum insulation resistance at 500 VDC and 500 VAC dielectric withstand voltage.
- Bearing System & Environmental Reliability: Heavy-duty dual ball bearing mechanism supporting continuous operation with IP68 environmental ingress resistance against particulate and moisture exposure.
- Control Signaling & Safety Protection: 4-wire lead termination providing pulse-width modulation (PWM) speed regulation, open-collector tachometer frequency output, electronic locked rotor protection, and reverse polarity safeguard.
