PV90-4

The PV90-4, 400Hz ground power unit (GPU), is the fourth generation of SAS’s solid state frequency converters and is now 30% more compact and with an efficiency >95%*. Emphasis is on all weathers ease of use, and the product’s ability to be serviced worldwide by local staff.

During ramp operations, whether wearing heavy gloves or operating in bright sunshine, the large 5.7” LCD display and oversized panel controls make power selection and system monitoring easy.

The latest PV90-4 is offered with horizontal and vertical mounting options to suit all operations.

From conception, the SAS PV90-4 was designed to be a zero downtime GPU requiring a minimum of planned maintenance.

Achieving zero down time requires design modularity. The unique feature of the SAS PV90-4 is the pluggable (SWAP-OUT) Power Module. The ‘heart’ of the system can be easily replaced by first line maintenance staff in a matter of minutes.
Because all power stage components are housed in a single pull out module, replaceable in minutes; a one-fix solution is available for almost any fault. No matter where the PV90-4 is situated in the world, the repair does not need a factory trained engineer.

In summary, the PV90-4 has been designed for the airport, the airlines and the ground crew, ensuring minimum maintenance and maximum longevity.
