SmartSwitch DC4: Advanced 4 Channel CAN-Controlled DC Switch & Dimmer (12-24V DC, 15A)
Please contact us if you need installation and Venus OS updated.
Seamless Digital Control for Modern Electrical Systems
Engineered for precision and performance, the SmartSwitch DC4 is a revolutionary 4-channel digital DC switch and dimmer, fully controllable via CAN bus with a single RJ45 VE.Can pinout. Operating on both 12V and 24V systems and delivering up to 15A, this compact module redefines electrical integration for RV, marine, off-grid, caravan, tiny home, and industrial applications.
Transform Your Electrical Control System
SmartSwitch DC4 eliminates outdated manual switches by enabling one-touch control of your DC loads. With seamless integration into Victron Cerbo systems and complete CAN communication capability, it’s a game-changer for smart energy solutions.
- Single-cable connection for simplified wiring
- One-touch control of DC lights or loads
- Multi-mode functionality: On/Off, momentary, dimming
- Integrated load protection: Overcurrent and over-temperature safeguards
- Victron Cerbo compatible and plug & play ready
Flexible and Customisable Channel Features
Each of the 4 independently configurable channels can be set to:
- Switch DC loads on/off (latched)
- Provide dimming through 120Hz PWM
- Act as a digital input for feedback and control
Built-in Safety and Monitoring
Featuring internal power isolation, the DC4 ensures robust operation with enhanced diagnostics:
- Current monitoring up to 30A full scale
- Over-current protection with simulated ATO fuse characteristics (2A, 3A, 4A, 5A)
- Over-temperature protection at module and channel levels
- Output voltage sensing for real-time load and input monitoring
Future-proof your setup with the potential for upcoming analogue voltage measurement upgrades and advanced digital input capabilities.
Firmware Compatibility Notice
Firmware Requirement: The SmartSwitch DC4 is currently compatible with GX Firmware versions v3.60 to v3.76. When updating your GX device, please ensure it remains within this firmware range to maintain optimal performance and full feature support for the SmartSwitch.
