User Manual


The FRU-1040 chassis with integral DC power supply provides a means of mounting either one or two IRT Eurocard modules in a single rack unit, where only a low voltage DC supply is available. This provides a convenient format for situations where only a small number of modules are required and space is at a premium.

The FRU-1040 differs from the AC 1 RU chassis only in the provision of a DC supply input in the range of 20 to 70 Volts instead of the AC mains input. The DC input may be either positive or negative earth.

The FRU-1040 is supplied with blank plates covering the right hand module position to enhance the safety and appearance of the unit when only one card is fitted.

A single power supply only is provided, so if power supply redundancy is required users should select one of IRT's 3 RU frames.
