For use in areas with an explosion risk in Zone 2, Phoenix Contact presents two compact Quint Power power supplies and a Quint Diode redundancy model with type 'n' explosion protection in accordance with EN 50021. The explosion protection type 'n', conceived for use of operating materials in Zone 2, incorporates established industrial standards that are adapted to the specific features of explosive gases.
The power supplies have a regulated and adjustable output voltage of 22,5-28,5 V with an output current of 5 A and 10 A. Consistent implementation of a wide input range from 85 to 264 V a.c. or 90 to 250 V d.c. ensures operation on all standard power grids worldwide. A potential-free relay contact and an active transistor switching output provide preventive function monitoring. To achieve 100% redundancy, the power supplies can be connected in parallel using the redundancy module.
An international certification package including the ATEX guideline with norm EN 50021 and the UL standards for Class 1, Division 2, which are particularly important for areas with explosive substances, enables worldwide use. Quint Power also fulfills the requirements of the CB scheme, Germanischer Lloyd as well as UL 60 950 for information technology installations and UL 508 for industrial control installations.
