Detailed Product Introduction

The Chaoyang 4NIC-B Series is a professional line of linear DC power supplies built for stable, long-lasting industrial power conversion. The series is split into two input configurations to match global industrial power grids: single-phase models compatible with AC220V±10% 50Hz power, and three-phase 3P models compatible with AC380V±10% 50Hz power. Each model is assigned a fixed output power rating and compact, standardized mechanical dimensions for easy panel mounting and equipment integration.
Every 4NIC-B unit is manufactured with industrial-grade internal components, optimized circuit design, and rugged enclosure construction to eliminate voltage fluctuations, surge damage, and intermittent power output. This series is purpose-built for direct integration into industrial machinery, drilling rig controls, automation systems, and precision electrical equipment, with model-specific power ratings and sizes to fit exact installation and power demand requirements.
Functional Performance & Value Highlights
- Ultra-Stable DC Output: Delivers ≤±1% voltage regulation accuracy, eliminating power spikes and dips that damage sensitive industrial electronics and ensure consistent equipment operation.
- Wide Power Range Coverage: Covers 5.6W to 30000W (single-phase) and 50W to 15000W (three-phase), providing a tailored power solution for low-power sensors to high-power industrial machinery.
- Continuous Duty Reliability: Engineered for 24/7 non-stop operation with a mean time between failures (MTBF) exceeding 50,000 hours, reducing unplanned maintenance and downtime.
- Wide Voltage Compatibility: Tolerates ±10% input voltage fluctuations, maintaining stable output even in unstable grid environments common in industrial and drilling sites.
Structural & Engineering Features
- Standardized Compact Enclosures: Fixed dimension casings (from 80*95*37mm to 800*550*400mm) for easy panel mounting, cabinet integration, and equipment retrofitting.
- Rugged Industrial Construction: Shock-resistant, dust-proof outer casing protects internal circuitry from vibration, debris, and harsh industrial conditions.
- Overload & Surge Protection: Built-in over-voltage, over-current, and short-circuit protection to safeguard both the power supply and connected equipment.
- Efficient Heat Dissipation: Optimized internal thermal design and enclosure ventilation prevent overheating, even under full-load continuous operation.
Applicable Operating Conditions
The Chaoyang 4NIC-B Series DC power supplies are engineered for demanding industrial and field environments where stable DC power is critical, including:

Field Fault Repair & Replacement Cases
Case 1: Drilling Rig Control Panel Power Failure
A drilling rig’s local control panel lost power due to a faulty 4NIC-B25 DC power supply, halting rig instrumentation. Replacing the unit with a new 4NIC-B25 (25W single-phase) restored stable 220V-to-DC conversion, getting the control panel back online immediately.
Case 2: Factory Automation System Voltage Fluctuation
An automated production line experienced erratic sensor operation caused by unstable output from an aging 4NIC-B3P120 (120W three-phase) power supply. Installing a replacement 4NIC-B3P120 eliminated voltage fluctuations, fixing sensor misreadings and resuming production.
Case 3: High-Power Industrial Equipment Shutdown
A large industrial machine shut down repeatedly due to insufficient power from a worn 4NIC-B2000 (2000W single-phase) supply. Upgrading to a new 4NIC-B2000 unit provided consistent full-power output, resolving unexpected shutdowns.
Frequently Asked Questions (FAQ)
| Question | Answer |
| What is the input voltage difference between standard and 3P 4NIC-B models? | Standard 4NIC-B models use single-phase AC220V±10% 50Hz input, while 3P models use three-phase AC380V±10% 50Hz input, matching different industrial grid setups. |
| Are 4NIC-B power supplies suitable for harsh drilling site environments? | Yes, these units feature rugged, vibration-resistant enclosures and wide input voltage tolerance, making them ideal for drilling rigs and industrial sites with unstable power. |
| How do I select the correct 4NIC-B model for my equipment? | Choose based on three key factors: required output power, available input power (single/three phase), and allowed mounting dimensions to ensure a perfect fit. |
