PBM Motor and Fan (Suzhou) Co., Ltd.  

Product Name: 300mm Ec-AC Axial Fan with Power-Saving Model NO.: PW3N300B48H Certification: RoHS, CE Electric Current Type: DC Type: Axial Fan Blade Material: Stainless Steel Material: metal Fan Feature: 0~10VDC/PWM Speed Control, Tach Output Usage: Telecom Station, Heat Exchanger, Free Cooling Unit Cooling Method: Direct Cooling Trademark: PBM Transport Package: Standard Specification: CE Origin: Suzhou HS Code: 84145199 Product Description 300mm EC-DC Axial Fan with Power-SavingPBM Motor and Fan is a China mainland manufacturer and EC technology consulting company offering an extensive range of EC(Electronically Commutated) motors, fans and solutions, investing in the latest developing, manufacturing and technical equipment with in-depth processes & procedures. Our main products are EC fans, including EC axial fans, EC centrifugal fans and EC blowers. We do both AC and DC current type. And EC Motor is the core technology of our products.Eletronically Commutated Motors(EC Motors)also known as Brushless DC Motors(BLDC) are synchronous electric motors powered by direct-current(DC) electricity and having electronic commutation systems,rather than mechanical commutators and brushes.The current-to-torque and voltage-to-speed relationships of BLDC motors are linear.PBM fans are widely used in many fields. For example, axial fan for telecom, backward curved centrifugal fan for air exchanger,(inline duct fan)hydroponic products and FFU, forward curved centrifugal fan for air purifier and air conditioning,blower for kitchen.Fan type:DC axial fanRated Voltage: 48 VDCOperating Voltage: 36~57 VDCLow-Start Voltage: 30VDCRated Speed:2000RPMInput Current: 2.5AInput Power: 120WAir Flow: 1371CFM /2330m3/HStatic Pressure: 1.26inH2O /316PaAcoustical Noise: 65dB(A)Life Expectance: 50,000Hours(L10)At 40ºC room, humidity 15%~65%RH.Direction of Rotation: Anti-clockwise seen on motorDirection of Air Flow: All aroundInsulation Class: Class BInsulation Resistance: 50 Mega Ohm minimum at 500VDCBetween frame and (+) terminalMotor Protection: Locked rotor protectionPolarity protectionAutomatic restart capabilitySpeed Control: Control input 0~10VDC / PWMProtection Type:IP44Dielectric Strength:10mA maximum at 1000VAC 50Hz five secondBetween frame and (+) terminalSignal Output:FG (Frequency Generator)Mounting Position:AnyBearing System:NMB ball bearingLead Wire:Red , Blue AWG18#; Yellow, White AWG22#Locked-rotor Protection: Over-current limiting circuit protects motor from damage at least for 72 hours of locked rotor condition at rated voltage.Maximum Current under Locked Rotor:A, Typical inrush current when the motor is trying to re-start under locked rotor conditions is 2~4 times the normal running current reoccurring and for 16~20% of restarting cycle period.B, If he CL function is used this restarting inrush current is about the same as the normal running current.Reverse Polarity Protection:No damage if the positive and negative leads are reversed under maximum operation voltage conditions.Over Voltage Protection:The circuit will be shut down automatically when input voltage over 60VDC. And re-started when Voltage down to 60VDC below.Soft Start:In 5 seconds after power on and speed control voltage gets to 1.5V or PWM duty cycle at 10% above.ModelMotor TypeBearingSystemRatedVoltageOperatingVoltageRatedCurrentRated PowerRatedSpeedAir FlowAirpressureNoiseLevelPart NO.TypeB / SVDCVDCAWRPMCMHPadBAPW3N300B48HBE92DC-TBALL4836~572.51202,000233031665
