THB1448AE Delta 139.7×139.7x38mm Ball 48VDC 1.32A 325.90CFM(9.230m3/min) 1.650inchH2O 66.8dB(A) 52.80W 6100RPM 4-wire leads fan
Delta THB1448AE is a DC brushless axial flow fan with a nominal voltage of 48VDC (operating voltage 36-60VDC), maximum input current of 1.32A, power of 63.36W, and rotational speed of 6100RPM. It delivers a maximum air flow of 9.23m³/min (minimum 8.31m³/min) and maximum static pressure of 41.85mmH₂O (minimum 33.90mmH₂O), with an average acoustic noise of 66.8dB(A) (maximum 69.8dB(A)). The frame is die-cast aluminum, impeller is UL 94V-0 flame-retardant plastic, and double ball bearings are used, weighing 590g. Rotating clockwise from the nameplate side, it has UL 1007-F AWG#24 leads (red+ black- blue FG yellow PWM). Operating at -10°C to 70°C, storing at -40°C to 75°C, it features locked rotor protection (fire prevention within 96h of lock-up) and reverse polarity protection, with a 70,000-hour lifespan at 40°C/15%-65%RH. Supporting 20kHz PWM speed control (0-10VDC, 0%-100% duty cycle) and FG speed signal output (open collector mode), it suits high-power cooling in data center servers and industrial power supplies.
