4nic-Casic 4NIC-DC325/G – High-Reliability Industrial DC Converter | 4NIC Series Platform
Engineering Background
The 4NIC series from 4nic-Casic (CASIC Group subsidiary) was developed specifically for mission-critical industrial power conversion applications where output stability, EMI immunity, and long service life are non-negotiable. The 4NIC-DC325/G represents the high-capacity variant within this series, engineered to deliver regulated DC output in demanding factory-floor and control-cabinet environments.
Product Positioning
Designed for procurement engineers sourcing reliable DC power conversion modules for PLC control panels, DCS cabinets, and industrial automation systems. The 4NIC-DC325/G is a direct-fit replacement and upgrade path for legacy power supply modules requiring stable, isolated DC output at rated capacity. Konmask.com supplies verified OEM units with full traceability documentation available on request.

Engineering Advantages
- CASIC Pedigree: Manufactured under the China Aerospace Science and Industry Corporation (CASIC) supply chain — a benchmark for reliability in Chinese industrial electronics.
- High Output Capacity: 325 W rated output supports multi-axis and multi-module control architectures without derating.
- Galvanic Isolation: Eliminates ground loop interference between control and power circuits — critical for signal integrity in mixed-signal cabinets.
- Comprehensive Protection: Multi-layer protection (OVP/OCP/SCP/thermal) ensures safe operation under fault conditions without cascading failures.
- Long Service Life: Industrial-grade components rated for extended MTBF — reduces unplanned downtime and maintenance cycles.
- Drop-in Compatibility: Designed for standard DIN rail and panel-mount integration — minimises retrofit engineering effort.
System Architecture & Signal Flow
The 4NIC-DC325/G operates as a DC/DC conversion stage within the control cabinet power architecture:
- Input Stage: Accepts DC bus voltage from upstream rectifier or UPS output; input filtering suppresses conducted EMI from upstream switching noise.
- Conversion Stage: High-frequency switching topology with transformer isolation; regulated output maintained across load variation.
- Output Stage: Filtered, regulated DC output distributed to PLC CPU, I/O modules, HMI, and field instruments via terminal block or bus bar.
- Protection & Monitoring: Internal protection circuits respond to over-voltage, over-current, and thermal events; status indication via LED or signal contact (confirm with datasheet).
Recommended integration: Install upstream of PLC power rail; ensure input cable sizing matches rated current; maintain minimum clearance per datasheet for thermal management.
