DC fans for telecoms systems
28 September 2011
Circuit & System Protection
Orion Fans has developed a new line of DC fans specifically for telecom applications.
Designated the OD1238-60HB series, the fans operate on input voltages from 36 V d.c. to 72 V d.c., making them suitable for telecommunications equipment due to their ability to accept these higher voltage inputs without sustaining damage. The fans measure 120 x 38 mm and deliver airflow of 115 cubic feet per minute (CFM).
The OD1238-60HB series fans are constructed with PBT, UL94V-0 plastic frame and impeller. They feature a dual ball bearing system and an auto restart, IC-protected brushless DC motor with input voltage ratings from 36 to 72 V d.c. and a nominal voltage of 60 V d.c. Airflow is 115 CFM, with speeds rated at 2600 RPM and maximum static pressure from 0,30 H2O. Options available include tachometer output, locked rotor alarm and IP55 sealing, as well as pulse width modulation (PWM) and constant speed controls. Operating temperature ranges from -20°C to +70°C, with a life expectancy of 65 000 hours at 45°C.
