SITOP PSE200U 10 A – 4-Channel Selectivity Module for 24 V DC Distribution

The SITOP PSE200U 10 A is a 4-channel electronic selectivity module designed to enhance any 24 V DC power supply by distributing the load current to multiple feeders and continuously monitoring each branch. It reliably detects overloads and short-circuits in one or more feeders and disconnects only the affected branch, while the remaining feeders continue to be supplied with 24 V DC. This helps minimize unplanned downtime and increases overall system availability.

Key benefits

• Selective 24 V DC distribution to four independently protected feeders to prevent a single fault from shutting down the entire system.
• Reliable overload and short-circuit detection, including high-resistance lines and “creeping” short-circuit conditions.
• Tolerates short current peaks (e.g., high inrush currents during switch-on) to avoid nuisance tripping, but disconnects in the event of sustained overload.
• Uninterrupted supply for healthy feeders – intact channels remain powered without interruption or reaction effects, helping keep the plant running and reducing downtime.
• Fast fault identification via channel LEDs and a group signaling contact.
• Universal use across industries and applications where dependable 24 V DC supply distribution is required.
