Pepperl+Fuchs PS3500 High Integrity Power Supply

Pepperl+Fuchs PS3500 universal power supply supports 90-230VAC and 90-300VDC inputs with a 15A @ 24VDC adjustable output.  The PS3500 backplane comes in two different sizes, a 3-unit and a 6-unit backplane.  Best of all, the PS3500 is completely backwards compatible and interchangeable with the previous generation PS2500 in case your application needs it.

The PS3500 can be used in Class 1, Div 2 and ATEX Zone 2 installations, and is ETL listed for US and Canada.  It also has UL approvals for US and Canada.  The PS3500 offers improved diagnostics capabilities and will be easily integrated into overall system diagnostics in the future.  An optional diagnostic module can be added to the backplane to provide real-time input and output power monitoring.

Oil & gas, petrochemical and chemical industries benefit from the PS3500’s system integrity and prevention of downtime, which could be very expensive even for a short period of time.  With the N+1 feature, cabinet space is kept to a minimum.  The PS3500 is also hot swappable from the backplane.
