🏙️ Technical Comparison of ONCCY EDS1 vs EDS7 DC Disconnect Switches

📍 As professional DC disconnect switch product lines, EDS1 and EDS7 series feature differentiated positioning in electrical parameters and functional configurations:

🔊 Performance Specifications

⚡ EDS1 Series:

Rated current: 9-32A

Supports 2P/4P configurations

Suitable for standard voltage scenarios

⚡ EDS7 Series:

Expanded current range: 3-63A

Maximum voltage: 1600VDC

2P to 10P multi-pole configurations

Modular structure allows up to 5 parallel connections for high-capacity systems

🔌 Installation Flexibility

⚡ Both series support DIN rail, panel mounting, and door interlock installations.

EDS7 adds single-hole mounting capability.

EDS1: IP66-rated plastic housing, ideal for direct placement in combiner boxes.

EDS7: Industrial-grade enclosure design for enhanced system scalability.

Operating Mechanism

EDS1: Offers 5 handle options – non-locking/direct-locking/external non-locking/external black-blue/red-yellow lock.

EDS7: Includes color-coded safety lock systems (red/yellow warning locks) for visual hazard alerts and operational permission management.

Selection Guide:

EDS1 is recommended for medium to small-scale DC power distribution systems.

EDS7 excels in high-voltage, e.g., photovoltaic energy storage, industrial control with its extended current range, modular architecture, and safety lock system. Choose based on voltage level, current load, and safety requirements.
