HES AQD4-4C1R1 Supervised Power Supply 12/24VDC
The HES AQD4-4C1R1 is a supervised 12/24VDC power supply engineered for access control and security system installations requiring reliable, monitored power delivery. With 4A output capacity and integrated fault-tolerance architecture, this unit provides active system supervision and circuit-level protection for controllers, readers, and auxiliary devices across distributed security deployments.
Key Features
- Dual voltage operation: 12VDC or 24VDC selectable output
- 4A maximum output capacity for multi-device support
- Integrated PTC (Positive Temperature Coefficient) circuit protection
- Dedicated 1A fault-tolerant monitoring output
- Active supervision and real-time fault detection
- Reduced system diagnostics time and improved installation reliability
- Compatible with HES and third-party access control systems
Technical Highlights
The AQD4-4C1R1 incorporates supervised power delivery with independent circuit monitoring via its dedicated 1A fault-tolerant output. This architecture enables active status reporting and circuit integrity verification without requiring additional monitoring hardware. The integrated PTC protection automatically manages overcurrent conditions, extending device lifespan and reducing nuisance shutdowns common in unsupervised supplies.
The unit's fault-tolerant design ensures that critical security circuits remain operational even during partial failures, maintaining system integrity in mission-critical installations. Selectable 12VDC or 24VDC operation provides flexibility for integration with diverse access control platforms and legacy systems.
Applications
- Access control system power distribution
- Door controller and strike supply
- Card reader and credential device power
- Distributed security installations with multiple endpoints
- Systems requiring active power supervision and fault monitoring
