PHOENIX CONTACT QUINT-ORING/24DC/2X10/1X20 POWER SUPPLY 24VDC 2X10A 20A 2320173

The Phoenix Contact QUINT-ORING/24DC/2X10/1X20 (PN: 2320173) is an active redundancy module designed for DIN rail mounting, engineered to maximize the operational reliability of critical industrial power supplies. Unlike passive solutions, this module utilizes Auto Current Balancing (ACB) technology to ensure that load current is automatically and symmetrically distributed between two connected power supplies .

This active distribution effectively doubles the service life of your redundant power supply system by preventing one unit from aging faster than the other . The device supports a 24 V DC input and provides flexible output configurations, allowing the module to function as either a 2 x 10 A dual output or a combined 1 x 20 A single output.

Included with the unit is the UTA 107/30 universal DIN rail adapter, which simplifies mechanical mounting and ensures a secure fit in standard industrial cabinets . Additionally, the unit features a protective coating, making it suitable for harsh environments where condensation or corrosive gases may be present .

Key Features & Benefits

• Auto Current Balancing (ACB) Technology: Balances the load within a voltage difference of just 0.3 V. This prevents thermal stress on individual power supplies, extending the life of the redundant system by up to 100% .

• High Energy Efficiency: Utilizes MOSFET transistor technology rather than traditional diodes. This results in up to 95% less power loss and heat generation compared to conventional decoupling methods, saving energy and reducing cooling costs .

• Flexible Output Configuration: Provides two output channels that can be used to supply separate 10A loads or can be paralleled on the output side to support a single 20A load .

• Comprehensive Monitoring: Features “Red OK” relay contacts and LED status indicators to provide permanent monitoring of the redundancy function, allowing for visual and remote fault diagnosis .

• Integrated Surge Protection: Built-in overvoltage protection activates at voltages exceeding 32 V DC, shutting down the affected input to protect the load from dangerous voltage spikes .

• ATEX & IECEx Certified: Approved for use in potentially explosive atmospheres, making it suitable for process industry applications (Zone 2) .
