Product Details

The Victron Energy Cyrix-ct 12/24V-120A Intelligent Battery Combiner Retail is designed to manage dual battery systems by automatically connecting and disconnecting batteries based on voltage levels. This ensures that batteries are charged efficiently without the need for increased output voltage, making it an excellent replacement for diode isolators.

Key Features

  • Automatic Voltage Detection: Automatically detects system voltage (12V or 24V).
  • No Voltage Loss: Ensures efficient power transfer without the need for increased output voltage.
  • Start Assist Feature: Allows manual parallel connection in emergencies.
  • Overheating Protection: Disengages during excessive temperatures and re-engages once cooled.
  • LED Status Indicators: Provides clear visual feedback on system status.
  • Dimensions: 46 x 46 x 80 mm.
  • Weight: 0.11 kg.
  • Control Cable: Includes a 1-meter control cable.
  • Ingress Protection: IP54 rated for protection against dust and water.
  • Cranking Rating: 180A for 5 seconds.
  • Continuous Current: 120A.
  • Connect Voltage: From 13.0V to 13.8V (12V system) or 26.0V to 27.6V (24V system).
  • Disconnect Voltage: From 11.0V to 12.8V (12V system) or 22.0V to 25.7V (24V system).
  • Current Consumption: <4 mA when open; 220 mA (12V) or 120 mA (24V) when closed.

Applications

Ideal for off-grid, marine, and RV applications where dual battery systems are used. The Cyrix-ct ensures that both batteries are charged efficiently and are disconnected when not in use, preserving battery life and system efficiency.

Product Specifications

Performance Specifications

  • Continuous Current: 120 A
  • Cranking Rating (5 seconds): 180 A
  • Connect Voltage: From 13 V to 13.8 V (12V system) or 26 V to 27.6 V (24V system) with intelligent trend detection
  • Disconnect Voltage: From 11 V to 12.8 V (12V system) or 22 V to 25.7 V (24V system) with intelligent trend detection
  • Current Consumption (Open): < 4 mA
  • Current Consumption (Closed): 12V: 220 mA | 24V: 120 mA
  • System Voltage Detection: 12/24V Auto-ranging

Key Features

  • Intelligent Battery Monitoring: Prevents unwanted switching by looking at the general voltage trend (increasing or decreasing). It reverses action only if the trend has reversed during a specific period, with time delays depending on the voltage deviation.
  • No Voltage Loss: FET-based alternative to diode isolators, maintaining full charge voltage to the batteries.
  • Bidirectional Voltage Sensing: Senses the voltage of both connected batteries, allowing it to engage if either the starter battery or the accessory battery is being charged.
  • Prioritising the Starter Battery: In a typical setup, the alternator is connected to the starter battery; the Cyrix engages to allow parallel charging of accessory batteries only after the starter battery has reached its connect voltage.
  • Protection Against Overheating: Features built-in thermal protection that will disengage the relay in case of excessive contact temperature due to long-duration overload.

Installation & Emergency Features

  • Start Assist: Allows for a parallel connection in case of emergency. The Cyrix can be engaged manually with a push button or switch to connect batteries for 30 seconds, which is useful if the starter battery is discharged or damaged.
  • Dual Power Supply: The unit will close even if the voltage on one battery is too low to operate the Cyrix, provided it is not lower than 2V (12V system) or 4V (24V system).
  • Long Connection Bolts: Equipped with 13mm M6 bolts to allow for the connection of more than one power cable.

Mechanical Specifications

  • Dimensions (H x W x D): 46 x 46 x 80 mm (1.8 x 1.8 x 3.2 inches)
  • Weight: 0.11 kg (0.24 lbs)
  • Connection Type: M6 Bolts
  • Protection Category: IP54
  • Operating Temperature Range: -40 to +60°C
