Power supply delivers functional safety applications

PHOENIX CONTACT QUINT SIL 3 power supply provides IEC 61508 SIL-certified power supply solutions to fulfill critical safety requirements. The strict safety requirements of these solutions are associated with a low probability that a system will fail to preform properly. The overvoltage protection (OVP) circuitry built into the QUINT4-PS/1ac/24dc/20 (2904602) power supply and the QUINT4-S-ORING/12-24dc/1X40/+ (2907753) redundancy module have been certified to the electrical safety in accordance to IEC 61508 and multiple EMC standards. The OVP circuitry build in the Phoenix Contact QUINT4-PS/1ac/24dc/20 (2904602) with the redundancy module QUINT4-S-ORING/12-24dc/1X40/+ (2907753) can be used to set up single or redundant bulk power system with a proven OVP. This system can be used in SIL 3 applications according to IEC 61508. The safety function is to limit the output voltage to 32Vdc.
