System Role
The HPK2-3 functions as the primary or redundant power source for Honeywell control system components, including PLC controllers, I/O modules, communication adapters, and fieldbus couplers. It converts AC mains power into a stable, regulated 24 VDC supply, ensuring reliable operation of all connected loads.
In typical installations, the HPK2‑3 is mounted on a DIN‑rail within a control cabinet and distributes DC power via a shared bus or direct terminal connections. Its integrated protections prevent damage from voltage transients, overloads, or wiring faults, enhancing system availability and safety.
For high‑availability applications, two HPK2‑3 units can be paralleled with appropriate redundancy diodes to provide N+1 redundancy, ensuring uninterrupted power even during a single module failure.

- HPK2‑3 is designed for use with Honeywell control systems and is not intended for generic commercial electronics.
- For redundant configurations, use HPK2‑RED redundancy modules to ensure proper load sharing and isolation.
- Ensure total connected load does not exceed 72 W (3 A @ 24 VDC) to maintain regulation and reliability.
- Verify input voltage configuration before commissioning; the module accepts 85 – 264 VAC.
Applications
The HPK2‑3 is deployed in a wide range of industrial control applications where reliable 24 VDC power is required.
FAQ – Frequently Asked Questions
HPK2‑3 provides a nominal output current of 3 A at 24 VDC, delivering up to 72 W of continuous power.
Yes. Two HPK2‑3 units can be paralleled using an external redundancy module (e.g., HPK2‑RED) to provide N+1 or 1+1 redundant power.
It is rated for industrial environments with an operating temperature of -25°C to +70°C, but for outdoor use, additional enclosure protection (IP54 or higher) is recommended.
It includes overvoltage, overcurrent, short‑circuit, and overtemperature protection to safeguard connected equipment.
While it is designed for Honeywell systems, it can be used with any 24 VDC load within the 3 A capacity, provided proper connections and protections are observed.
HPK2‑2 provides 2 A (48 W) output, while HPK2‑3 provides 3 A (72 W). Both share the same mechanical form factor and protection features.
