Product Description
Overview
The QUINT-ORING/24DC/2X10/1X20 is an active redundancy module designed for DIN-rail mounting. It ensures 100% decoupling of two parallel 24V DC power supplies, enhancing system reliability for critical industrial applications. With Auto Current Balancing (ACB) technology, it evenly distributes load currents, extending the lifespan of redundant power systems.
Key Features
-
Active redundancy: Ensures uninterrupted power supply by isolating faults in wiring or power units.
-
Auto Current Balancing (ACB): Equalizes current load across power supplies, reducing stress and improving service life.
-
Preventive function monitoring: Detects loss of redundancy via LED indicators and floating signal contacts.
-
Low power loss: High 98% efficiency, minimizing energy waste.
-
Surge protection: Built-in varistor protection against transient surges and polarity reversal.
-
Compact and durable: Steel housing with IP20 protection, ideal for industrial environments.
