Description
1. At-A-Glance Executive Brief
- Model: CHCMS-500
- Brand: Chungsol Marine
- Part Type: Marine AC Motor Controller / Speed Regulator
- Lifecycle Status: Specialized Marine Support Tier
- System Compatibility: Single-Phase Marine Automation Systems
- Core Protocol: Analog / Discrete Speed Control Interface
2. Technical Introduction
- Problem: Unexpected motor controller failures on marine auxiliary equipment can disrupt onboard ventilation, fluid pumping, or mechanical actuator loops while vessels are underway.
- Agitation: Procuring unverified commercial-grade replacements for marine environments risks premature component failure from humidity, vibration, and unstable shipboard power grids.
- Solution: The Chungsol Marine CHCMS-500 delivers rugged single-phase AC motor regulation designed specifically to handle shipboard electrical variations, restoring precise speed control without complex system modifications.

- Output Rating: Designed for fractional horsepower single-phase AC motors (up to 300W compatible specs)
- Mounting Configuration: Panel / Enclosure Chassis Mount
- Condition Availability: New Surplus (NSFP) / Fully Refurbished
- Operating Environment: Marine Grade / Engine Room & Control Console
- Lead Time: Same-day dispatch for active stock inventory
4. Field Engineer’s Tech Notes
- Grid Voltage and Frequency Stability: Verify that the incoming shipboard 220VAC power source remains within nominal tolerances before energizing the CHCMS-500. Severe frequency fluctuations common on auxiliary diesel generators can overheat internal SCR/TRIAC components.
- Motor Insulation and Load Matching: Ensure the connected single-phase motor windings are free of moisture contamination and ground faults. Connecting an unverified or damp motor can cause high leakage current, tripping internal protection circuits or damaging the output stage.
5. Adaptive QA & Testing Protocol
Incoming Chungsol Marine CHCMS-500 controllers undergo bench testing using a variable 220VAC single-phase power source and a matched dynamometer motor load. Technicians verify speed potentiometer linearity, test phase-angle firing stability under load, and check internal thermal regulation boundaries. Complete test validation logs and performance verification reports are available upon request prior to dispatch.
6. Buyer’s FAQ
- What warranty coverage applies to this marine controller? All units—supplied as New Surplus (NSFP) or professionally refurbished—include a full 12-month operational warranty from the invoice date.
- How fast can this part be delivered to my vessel or port facility? In-stock items ship same-day via priority international air courier to support urgent port calls and minimize vessel turnaround delays.
- Is the CHCMS-500 built for standard commercial marine grids? Yes, the unit is engineered to operate on standard 220VAC marine supply power. Verify your motor wattage and control requirements prior to ordering.
