Tubeaxial fan features high performance to space ratio

9 March 2005 Power Electronics / Power Management

The new Magnum 170 series of tubeaxial fans from Ametek Rotron, offers high performance to size ratio, delivering what the company says is twice the static pressure of similarly sized fans. The lightweight, compact fans are ideally suited for electronic cooling in servers, routers, electronics and telecom racks.

The 24 V d.c. high-performance Magnum 170 weighs 988 grams but delivers 365 CFM free delivery. It has an operating voltage range of 36 to 75 V d.c. and is UL, CSA and TUV certified. It also features solid-state circuitry, electronic commutation, locked rotor shut down protection, low-speed warning shut down, automatic restart and optional fan performance (speed) sensing.

The I²C version of the Magnum 170 weighs 952 g and delivers an airflow of 512 CFM free delivery. The I²C version offers microprocessor-controlled circuitry with an isolated 2-wire I²C/SMBus digital interface. It features closed-loop speed control over its entire operating voltage range and nine-user selectable addresses along with locked rotor shut down protection and fuse protection for safety.

The Magnum 170 series measures a compact 171,5x150, 4x50,8 mm. Its rugged construction includes a single-piece, die-cast aluminium venturi, high-temperature polymer propeller and a brushless DC motor with stainless steel ball bearings.
