HES AQD4B Supervised Power Supply Module 4A

HES AQD4B Supervised Power Supply Module 4A 12/24VDC

The HES AQD4B is a supervised power supply module engineered for mission-critical access control and security installations. Delivering regulated 4A output at selectable 12 or 24VDC, this module integrates seamlessly into HES systems and compatible third-party platforms, providing monitored power delivery with built-in supervision capabilities to detect anomalies and maintain system continuity.

Key Features

• 4A regulated output at 12 or 24VDC selectable
• Supervised power delivery with anomaly detection
• AC/DC conversion for flexible installation
• DIN rail or wall-mount form factor
• Compatible with HES access control systems
• Designed for secure electrical enclosure integration

Technical Highlights

The AQD4B operates as a Form Factor Power Supply Module with AC/DC capability, enabling deployment in environments requiring dual voltage compatibility. Supervision functionality monitors power supply status and alerts the connected security system to faults, ensuring rapid detection of power anomalies before they impact access control or reader operation. The 4A capacity supports multiple auxiliary loads including electrified locks, credential readers, and field devices in distributed security infrastructure.

Applications

Ideal for door control systems, badge reader networks, and facility-wide access control deployments where monitored auxiliary power is essential. The module's compact form factor and mounting flexibility make it suitable for retrofit installations in existing security cabinets and control panels. Commonly deployed in corporate campuses, government facilities, and infrastructure environments where power supply continuity and fault detection are critical operational requirements.
