Minebea's new fan tray includes six fan units, each maintaining 150ft3/min airflow.

Minebea's new fan tray includes six fan units, each maintaining 150ft3/min airflow.

The fan speeds are regulated in accordance with a preprogrammed speed/temperature profile, thus minimising acoustic noise, cold air thermal shock and current spikes at power up.

The supply voltage range of -39 to -75V DC makes it suitable for both -48 and -60V applications.

Benefits for customers include hot plug-in connection to a backplane system by slide-in blind mating connectors.

An alarm display can be attached to the front of the tray to indicate the states of various signals from the host backplane.

High reliability is guaranteed by careful derating of all components.

Minebea's new fan tray is particularly suited to work continuously under adverse environmental conditions.

Operating temperature ranges from -10 to +65C and will restart after exposure to -40 to +65C.

Safety features include fan cutoff in the event of fire and both visual and backplane alarms signalled in the event of power feed loss, fan fail, or thermistor failure.

The fan tray assembly has a minimum MTBF of 1Mh at 25C and has full CSA, NEMKO and CE approvals.
