RER101-36/12N/2HHPR-181

RER101-36/12N/2HHPR-181 DC Radial blower Particularly flat, pressure resistant fan developed especially for installation in equipment of compact dimensions with additional humidity protection. The DC drive employs an electronically commutated external rotor motor. Motor electronics is completely integrated into the fan hub. With additional sensor lead for speed monitoring General Data Nominal voltage V DC 12,0 Voltage range V DC 9 .. 13.6 -1 6000 Nominal speed PWM Speed control, 10 ...20 kHz • The fan is protected against reverse Speed tolerance polarity. 0% PWM • Electronic locking protection is integrated into the fan circuit. • Air exhaust radial.
