Victron Energy Cyrix-i 12/24V-400A (CYR010400000) is a fully automatic, high-power intelligent battery combiner relay. Unlike traditional diode isolators, it has zero voltage drop, ensuring full alternator and charger output reaches your batteries.
Its microprocessor-controlled design analyzes voltage trends over time to make smart, delayed decisions, avoiding unwanted cycling. It offers bidirectional voltage sensing, emergency start assist, status LED, and four selectable timing profiles. It is suitable for both 12V and 24V systems (auto-detecting), and is perfect for demanding applications such as marine vessels, large vehicles, and industrial systems.
Technical Specifications:
Model CYR010400000 (Cyrix-i 12/24V-400A) System Voltage 12V / 24V auto-ranging Continuous Current Rating 400A Peak Current (1 sec) 2000A Input Voltage Range 8 – 36 VDC Overvoltage Disconnect 16V / 32V Power Consumption (open) < 4 mA Start Assist Yes – 30 seconds manual override Micro Switch Yes – for remote status monitoring Status Indication Bi-colour LED Selectable Profiles 4 programmable connection/disconnection profiles Protection Class IP54 Dimensions (H × W × D) 78 × 102 × 110 mm Weight 0.9 kg
Key Features:
- Connects batteries in parallel when charge voltage is detected.
- Disconnects when voltage drops below float level to prevent discharge.
- Zero voltage loss – ideal replacement for diode isolators.
- Intelligent voltage trend detection prevents switching due to short load peaks.
- Supports emergency parallel connection for engine starting (Start Assist).
- Bidirectional voltage sensing and dual power input.
- Selectable switch profiles for different battery setups.
- LED status feedback for easy diagnostics.
Selectable Profiles:
- Profile 0: Delayed connect/disconnect based on 13–13.8V/12–12.8V ranges
- Profile 1: Fast connect after 30s over 13.25V; fast disconnect below 10.5V
- Profile 2: Connect after 6s above 13.2V; disconnect after 30s below 12.8V
- Profile 3: Gradual response with long delay based on wide voltage window
Typical Applications:
- Marine systems with multiple battery banks (starter, house, thruster)
- Off-grid power installations with multi-battery storage
- Heavy-duty vehicles with auxiliary power systems
Note: The Cyrix-i will not engage if one of the batteries is below 2V (12V system) to prevent unwanted switching during installation. Multiply thresholds by 2 for 24V and by 4 for 48V setups.
