Projecta IDC50XIQ 50A DC-DC Battery Charger with Intelli-IQ Support

The Projecta IDC50XIQ is a high-output 50A DC-DC charger designed for modern dual battery systems in 4WDs, caravans, and off-grid setups. Built for Australian conditions, it offers rapid charging from both alternator and solar sources, intelligent multi-stage charging, and seamless integration with Projecta's Intelli-IQ smart power management system.

Key Features

• 50A High-Speed Charging
  Delivers up to 50 amps for rapid charging of large auxiliary battery banks—ideal for lithium and high-capacity deep cycle systems.

• Dual Input with Solar Priority
  Accepts simultaneous alternator and solar input, with solar prioritised to reduce alternator load and fuel consumption.

• Multi-Chemistry Support
  Compatible with Lithium (LiFePO₄), AGM, Gel, Wet Cell, and Calcium batteries. Charge profiles are selectable for optimal battery care and performance.

• Built-In MPPT Solar Regulator
  The integrated Maximum Power Point Tracking (MPPT) controller ensures efficient solar charging, extracting the maximum power even in low light.

• Fully Sealed IP68/IP69K Enclosure
  Designed for harsh environments—dustproof, waterproof, vibration-resistant, and pressure-washer safe for under-bonnet or chassis mounting.

• Voltage Drop Compensation
  Automatically increases output voltage to account for cable losses, ensuring correct charge voltage at the auxiliary battery over long distances.

• Adaptive Charging
  Compatible with vehicles using smart alternators and start/stop technology. Reduces strain on the starter battery by adjusting charge behaviour when engine is off.

• Parallel Charging Capable
  Two IDC50X units can be connected in parallel (Master/Slave configuration) to provide up to 100A combined output.

• Comprehensive Protection
  Built-in safeguards include over-temp, over/under voltage, short circuit, and reverse polarity protection.

Intelli-IQ System & Smart Relay Integration

The IDC50XIQ connects to Projecta’s Intelli-IQ ecosystem via LIN Bus, allowing full integration with compatible displays, apps, and smart relays for a centralised and intelligent 12V power system.

• IQD2 Display Compatibility
  Monitor charge input (solar/alternator), current, battery voltage, and stage (Bulk, Absorption, Float) in real time. Alerts such as low voltage or thermal shutdowns are clearly indicated.

• Bluetooth & App Control
  Configure settings, update firmware, and monitor performance via the Projecta IQ App on iOS and Android. Also accessible via Apple CarPlay and Android Auto.

• Smart Relay Support
  Works with Projecta Smart Relays for advanced accessory control:

  • IQR040 (Single Channel, 40A):
    Supports voltage-sensitive switching, programmable timers, current sensing, and automatic disconnect features. Suitable for fridges, compressors, and other high-draw devices.

  • IQMR4 (4-Channel, 10A per channel, 30A max):
    Provides dimming, flash patterns (e.g. SOS, strobe), linked switch logic, and programmable schedules. Ideal for lighting, beacons, and low-draw loads.

All devices communicate through the LIN Bus, offering centralised setup, monitoring, and logic-based control from the IQD2 display or mobile app.

Installation Notes

• Cable Size
  Use 6 B&S (13mm²) cabling for all major connections (alternator, solar, aux, ground) for runs up to 12m. For longer runs, increase cable size accordingly.

• Fusing
  Use 80a fuses on both the input and output cables, mounted as close as possible to the respective battery terminals.

• Ignition Override
  For vehicles with smart alternators, connect the ignition wire to a switched 12V source using 1–1.5mm² cable and a 1–2A fuse.

• Solar Input
  Connect solar panels directly to the IDC50XIQ. If using panels with a built-in regulator, the regulator must be bypassed.

• Temperature Sensors
  Includes a 5m sensor loom. Connect to TEMP1 and TEMP2 inputs for accurate battery temperature compensation.
