Uninterruptible Power Supply PowerWalker AS400 Card 6 Terminal

PowerWalker AS400 Card 6 Terminal is an accessory for compatible PowerWalker AS400-series uninterruptible power supplies (UPS). The AS/400 Card provides clean dry contacts for remote monitoring and controlled shutdown of the UPS via external systems such as PLCs, signal control panels or building management systems. It reports discrete statuses including UPS failure, alarm, mains fail, bypass, battery low and UPS on, and allows remote shutdown when used with a separate 12 V or 24 V DC control supply.

Advantages

The AS/400 Card offers reliable isolated relay outputs that simplify integration with industrial control equipment and monitoring solutions. By providing clear contact signals for common UPS states, it enables automated responses from connected controllers without requiring complex communication protocols. The card’s terminal-based design supports straightforward wiring and maintenance in server rooms, network closets and control cabinets.

Suitable for

• Integration with PLCs and industrial control panels
• Remote UPS monitoring in server rooms and network infrastructure
• Automatic or supervised shutdown sequences for protected equipment
• Connection to alarm systems and BMS (building management systems)

Key specifications

• Interface type: Dry contact relay outputs (terminal connections)
• Signals provided: UPS failure, Alarm, Main Fail, Bypass, Battery Low, UPS On
• Control input requirement: external 12 V DC or 24 V DC supply for high signal
• Form factor: Card with 6 terminal connections for easy wiring
• Compatibility: Designed for use with selected PowerWalker AS400-series UPS models

How to use

Install the AS/400 Card into the designated interface slot of a compatible PowerWalker AS400-series UPS following the safety and installation instructions in the UPS user manual. Connect the card’s terminal outputs to the input terminals of the external controller, PLC or alarm panel according to the required signal mapping. Provide an external 12 V or 24 V DC control supply where a high signal is required for remote shutdown. Verify wiring and perform a functional test to confirm that each contact reflects the correct UPS status before placing the system into active operation.

Использование и рекомендации

Follow the pin assignment and wiring diagrams in the UPS user manual. Ensure the external control supply voltage is compatible and protected against transients. For integration with safety-critical systems, validate shutdown sequences and alarm responses in a controlled environment before deployment.
