II. Core Functional Characteristics

1. 8 independent power distribution, centralized management and hierarchical protection

As the core distribution node of the AC input in the cabinet, it provides a power distribution capability of 1 total input → 8 independent outputs. Each output is independently isolated, independently protected, and independently status-indicated. It can supply power to 8 1D series power modules or other AC loads, achieving centralized management and hierarchical control of the power supply chain, avoiding messy wiring, significantly improving the standardization and maintainability of the power supply system. The internal adopts high-conductivity copper busbars and industrial-grade terminal blocks, with reliable contact and strong current-carrying capacity, capable of long-term full-load operation, and eliminating the risks of false connection and overheating.

2. Each output has independent multi-level protection, fault isolation does not spread

Each output is equipped with an independent circuit breaker / fuse, with three safety functions of short-circuit protection, overload protection, and leakage protection. When a short circuit or overload occurs in a single path, it only cuts off the faulty circuit, without affecting the normal power supply of the other 7 paths, achieving rapid fault isolation and protecting the valuable power modules and control cards at the back end. The protection devices act quickly (≤10ms), have high precision, are convenient for on-site replacement and reset, and reduce the cost of fault handling, meeting industrial safety standards.

3. Wide AC input range, compatible with global power grids

Compatible with mainstream industrial power grids worldwide, with an AC input voltage range of 85–264 VAC and a frequency of 47–63 Hz. It can withstand complex working conditions such as grid fluctuations, frequency deviations, and voltage transients, and can operate stably without additional voltage stabilizing or frequency conversion equipment. The internal circuit has excellent electromagnetic compatibility (EMC), capable of resisting the influence of on-site motor startups, frequency conversion equipment, and high-frequency interference, with stable and undisturbed power distribution process, suitable for harsh industrial electromagnetic environments.

4. Compact modular design, high-density installation and rapid maintenance

Adopting the standard size of the 1D series, the structure is compact and small in volume, with a metal reinforced shell, weighing approximately 0.7 kg. It occupies little cabinet space, suitable for high-density cabinet layout, saving space and wiring costs. Rail-mounted snap-in installation, tool-free disassembly, supports online hot plugging, does not affect the operation of other equipment in the cabinet when replacing, significantly improving system maintainability. The shell is treated with anti-corrosion coating, dustproof, and vibration-resistant, suitable for harsh installation environments in industrial sites.

5. 8-channel status visualization, rapid fault location Equipped with a total power indicator light + 8 independent status indicator lights, the input power supply, branch output, and protection action status are clearly visible. On-site personnel can quickly determine the operation status of the power distribution system. Each path has independent fault self-checking, which can accurately locate short circuits, overloads, phase missing, etc., reducing the troubleshooting time; it supports fault dry contact signals being uploaded to the Ovation system, enabling remote monitoring, alarm, and event recording, and is compatible with intelligent operation and maintenance by Emerson.

6. High reliability and long lifespan, suitable for 7×24 continuous operation
