Power Supply for Applications to SIL 3

EP Editorial Staff | August 28, 2019

Quint Power line includes a single-device solution that meets functional safety applications to Safety Integrity Level (SIL) 3.

The QUINT 20+ power supply has an integrated decoupling MOSFET and double overvoltage protection circuitry to meet rigorous SIL 3 safety regulations without the need for external redundancy. The unit uses a single conformally coated device solution with ATEX, IECEx, and Class I, Division 2 approvals, which allows the power supply to be mounted within potentially explosive areas (Zone 2). Designed with double overvoltage circuitry, the power supply also has a Hardware Fault Tolerance (HFT) of 1.
