Phoenix Contact: SIL 3-Rated QUINT 10+ Power Supply
October 17, 2023
The new QUINT 10+ power supply from Phoenix Contact can help achieve SIL 3 rating without external redundancy.
The device has an integrated decoupling MOSFET and a redundant overvoltage protection (OVP) circuit, which eliminate the need for external components.
The QUINT 10+ power supply has a conformal coating and ATEX, IEC 61508, IEC 61511, and Class I, Division 2 approvals, so it can be mounted within potentially explosive areas (Zone 2). If the voltage rises above 30 V DC, the device will switch off within 20 milliseconds, creating a safe state with no output voltage. The power supply connected in parallel ensures reliable power.
The power supply has a 10 A nominal output current and an operating range of -40 to +75 degrees Celsius.
