Information About 1606-XLBUFFER
The 1606-XLBUFFER is part of the Allen-Bradley 1606 power supply accessory family, offering enhanced power stability for DC systems. Its construction features a compact IP20-rated housing with selectable buffered voltage settings, allowing configuration flexibility for various load requirements. This module integrates seamlessly with 24 VDC industrial power networks, supporting systems that require regulated backup energy during short disturbances. Typical applications include automation panels, PLC enclosures, and equipment relying on PELV/SELV-classified low-voltage power circuits and galvanic isolation.
Key Features:
- Selectable buffered voltage: Adjustable via front jumper for precise system matching.
- Wide DC input range: Supports 24–28.8 VDC with variable buffer thresholds.
- High buffering capability: Provides 0–20 A buffering current for stable output.
- Built-in protection: Reversed polarity and overvoltage immunity up to ±35 V.
- Defined hold-up performance: Guaranteed energy supply for brief outages under varying loads.
- Switched-mode design: Ensures efficient operation with low power dissipation.
- Industrial-rated enclosure: IP20 protection with durable construction for panel installations.
- DIN rail mounting: Streamlined integration into control cabinets.
The 1606-XLBUFFER delivers the reliability and precision required for industrial DC power stabilization and buffer applications.
