Critical operating states are therefore detected at an early stage. Thanks to active decoupling with MOSFET, you can save up to 70% energy by using the S-ORING module. OVP (overvoltage protection) protects downstream consumers from overvoltages greater than 30 V DC at the output. With 40 A, the module is suitable for DC voltages from 12 to 24 V. It has a narrow design of just 32 mm and are suitable for use on DIN rails. Thanks to the wide temperature range from -40 –‘ φͣ͜ϓ ǡ –Š‡›…ƒ „‡ —•‡† ƪ‡š‹„Ž› and are suitable for industrial use. With a protective coating and both ATEX and IEC Ex approval, it is also suitable for use under extreme ambient conditions. ർ Phoenix Contact is adding a customised solution for impedance-sensitive signal circuits with more than two signal wires to its Termitrab complete range of narrow surge protective devices for MCR technology. ർ The new VP version of the QUINT S-ORING module from Phoenix Contact extends the active redundancy modules of the QUINT power supply family. By decoupling and monitoring, it increases system availability. example. The lack of resistors in the protective circuit means there is no fundamental attenuation. There is no impact on the measuring signals.
