TJM 25A Dual Input DC-DC Battery Charger – DC25A

$399.00

Get more out of your 4WD with the TJM by Projecta DC25A intelligent DC/Solar battery charger. One of the toughest most advanced dual battery management systems available today. TJM’s DC25A allows you to charge your 12V second or auxiliary deep-cycle battery on the go. It is shock, vibration and dust proof, plus water resistant which makes it suitable for both in-vehicle and under-bonnet installation. Offering a host of features, the DC25A can charge simultaneously from both solar and alternator (9-32v) inputs, and function as an MPPT solar controller with dual charging modes for compatibility with both smart and conventional alternators. It comes loaded with a host of safeguard features including over/under voltage, anti-sparking, reverse connection and over-temperature protection systems for peace of mind. TJM’s DC25A is the easy to install and sets a new benchmark for DC-DC battery management.

Description

  • SWITCHMODE TECHNOLOGY – The DC25A converts your vehicle’s 12VDC/24VDC alternator power to the correct voltage level allowing your batteries to be fully charged, prolonging battery life and reliability. With the latest synchronous switching technology, efficiency of DC25A exceeds 94% at typical full load condition.
  • DUAL INPUT OPERATION – Allows two energy sources to power the DC25A simultaneously. Solar input takes precedence if solar and alternator inputs are present. When solar input cannot provide enough energy to the load, the DC25A will draw power from solar and alternator simultaneously.
  • SOLAR MPPT – The DC25A utilises sophisticated MPPT (Maximum Power Point Tracking) solar regulator technology. MPPT maximises the power generated from the solar panels to the auxiliary battery.
  • SUPERIOR 3 STAGE CHARGING – Using high speed microcontroller and proprietary charging algorithm, the DC25A delivers a sophisticated 3 stage charging process resulting in a faster and more powerful charge, ideal for deep cycle batteries. The first stage, bulk (constant current), charges the battery faster while the second stage, absorption (constant voltage), ensures the battery is thoroughly charged. The final stage, float, maintains the battery at a safe voltage allowing it to be maintained and ready for use indefinitely.
  • MULTI-CHEMISTRY SUPPORT – The DC25A supports GEL, AGM, WET and CALCIUM batteries. If the calcium battery mode is selected, periodic equalisation will be provided to the calcium battery for removing acid stratification.
  • IGNITION CONNECTION – The DC25A can be wired to the vehicle’s ignition allowing it to operate only when the ignition is turned on. The ignition connection also activates the lower input voltage operation to suit vehicles with smart (variable voltage) alternators.
  • TEMPERATURE COMPENSATION – The DC25A is supplied with a 2 metre temperature sensor. The sensor monitors the battery temperature and adjusts (compensates) the charger’s output to prevent overcharging. This is ideal for batteries used in warmer climates or environments.
