HPWR01G
Key Information
HPWR01G is a DC power redundancy distribution module from HollySys, designed for the HOLLiAS MACS-K series distributed control system (DCS). It is used to achieve redundant power supply configuration for 24 VDC or 48 VDC systems, typically paired with HPW2405G, HPW2410G, or HPW2420G power supply modules .
The HPWR01G provides a fail‑over solution by combining two power inputs into a single regulated output. It also includes the necessary terminals for distribution to downstream modules and includes protection features such as reverse polarity protection and overcurrent protection .
The "G" suffix indicates the general industrial version, conforming to IEC/EN 62368‑1 and EMC immunity standards (EFT, ESD, Surge) .
- DC power redundancy distribution
- 22–60 VDC wide input range
- 20 A max output current
- HOLLiAS MACS‑K DCS compatible
- Industrial G‑grade version
Functions
Redundancy & power distribution
- Dual input redundancy — Combines two 24 VDC or 48 VDC power inputs (from HPW series power supplies) into a single regulated output. If one input fails, the other automatically takes over without interruption.
- Power distribution — Provides multiple output terminals for distributing the redundant power to downstream modules, including controllers, I/O modules, and fieldbus segments.
- Wide input range — Accepts 22–60 VDC input, making it compatible with both 24 VDC and 48 VDC power systems.
Protection & monitoring
- Protection features — Integrated overcurrent protection, short‑circuit protection, and reverse polarity protection safeguard the module and connected loads .
- Status indication — LED indicators provide immediate visual feedback on input status, output status, and fault conditions.
- Wide temperature operation — Supports operation from -25°C to +70°C, suitable for outdoor cabinets and cold climates .

Installation
Proper installation of the HPWR01G redundancy module ensures reliable power availability for the DCS system.
Mounting & wiring guidelines
| Mounting position | DIN‑rail (EN 50022) inside control cabinet |
| Input connections | Two DC power inputs (from HPW series power supplies) |
| Output connections | Multiple output terminals for distribution to DCS modules |
| Wiring | 2.5 mm² (14 AWG) stranded wire with ferrules |
| Grounding | Connect ground terminal to cabinet ground |
| Ambient temperature | Ensure adequate clearance for airflow, especially at high ambient temperatures |
| Input protection | External fuses or circuit breakers recommended for each input |
- Mount the HPWR01G on a standard DIN‑rail within the control cabinet. Ensure sufficient clearance for wiring and ventilation.
- Connect the two DC power inputs to separate power supplies (e.g., HPW2410G or HPW2420G) to achieve true redundancy.
- When using the HPWR01G in a HOLLiAS MACS‑K DCS system, it is typically installed in the power distribution section of the cabinet .
- For outdoor or cold climate installations, the G‑grade variant supports operation down to -25°C .
- Use only copper conductors rated for the operating temperature and current capacity.
Lifecycle
Active currently in production — fully supported
Product status: The HPWR01G remains an active, supported product in HollySys's HOLLiAS MACS-K DCS portfolio. It continues to be the recommended redundancy module for new MACS-K power distribution systems.
Spare parts & support: Replacement units and terminal blocks are available through HollySys's standard support channels and authorized distributors.
Replacement & migration:
- When upgrading from older MACS‑K systems, ensure that the HPWR01G is compatible with the existing power supplies (HPW2405G/HPW2410G/HPW2420G).
- For new installations, consider the G‑grade version for extended temperature range applications.
- The HPWR01G is not designed for generic commercial electronics — it is specifically engineered for DCS/PLC power distribution .
Recommendation: For new HOLLiAS MACS‑K DCS installations, the HPWR01G remains the recommended power redundancy solution.
