EV-02-1540A

Function and construction of EV-02-1540A

The card is retained as a separate catalogue position rather than automatically merged with EV-0.2-1540A. The supplied image represents the same external fan family, but electrical and execution data must be confirmed from the individual nameplate and passport.

The fan is a component of the cooled equipment, not a complete ventilation installation. Air-path resistance, correct rotation, unobstructed inlet and outlet and the specified supply affect its installed performance.

Electrical and airflow parameters

Published family data associates this fan form with a compact high-frequency axial design for radio-electronic equipment. Because the exact EV-02 writing is not accompanied by a separate confirmed parameter table, numeric values from EV-0.2-1540A are not presented as guaranteed interchangeability.

Airflow and pressure refer to documented operating points and should be checked together. A visually similar fan with another suffix, voltage or frequency is not automatically interchangeable.

Operating conditions and inspection

The existing catalogue record specifies resistance to vibration from 1 to 2,000 Hz up to 150 m/s², shock acceleration up to 400 m/s², operation from −60 to +100 °C and relative humidity up to 98% at +35 °C. Operating time is listed as 5,000 h.

Incoming inspection should cover the marking, housing, impeller, connector or leads, mounting points and free rotation. Unusual noise, vibration, overheating, current deviation or reduced airflow requires investigation under approved maintenance documentation.

Related cooling fans and selection

Functionally related catalogue positions include EV-0.2-1540A and EV-0.2-1540. These links support navigation and do not establish electrical, mechanical or installation interchangeability.

Application to a specific aircraft, helicopter, ground unit or electronic block must be confirmed from its illustrated parts catalogue, wiring diagram or approved service documentation.

Identification and ordering

The designation may be encountered as EV-02-1540A; EV 02 1540A; EV021540A; ЭВ-02-1540А. These are writing and search variants; execution suffixes and nameplate marks remain significant.

An inquiry should state the complete marking, quantity, required condition, delivery set and documentation requirements. Other units are listed in the Cooling & Ventilation Fans category.
