Keep Your Auxiliary Batteries Charged with HULK Professional Series DC-DC Battery Chargers

Your vehicle’s alternator is not designed to fully charge auxiliary batteries. An insufficient charge may cause sulphation resulting in shorter battery life and impaired performance.

HULK Professional Series In Vehicle DC to DC Battery Chargers are available in either 25 or 40 Amp and are engineered to operate in the toughest conditions either under bonnet or in vehicle, charging your auxiliary batteries to their optimum level whilst driving or with solar when parked.

Fully Automatic and using a unique 7 Stage charging algorithm, the HULK Professional Series DC-DC battery chargers ensure your battery is charged to 100%, irrespective of size or type.

Features

• Automatic Input Selection

  Automatically selects the input, Alternator, Solar, DC, based on the Active input. No manual switching required.

• Dual Charging Mode

  Works with both fixed voltage (standard voltage 12-24V) and variable voltage (Smart Alternators).

• Ignition Connection

  Allows “Low Input Operation” suitable for variable voltage alternators.

• Multi-Chemistry Charging

  Capable of charging a variety of rechargeable batteries, like Lead Acid Wet / Flooded types, GEL, AGM, MF, Calcium and Lithium batteries.

• Solar MPPT Regulator

  Maximises the power available from solar panels even in low light.

• 7 Stage Intelligent Switch Mode Charging

  Unique charging algorithm enhances the life of batteries by ensuring a full charge and conditioning. It also recovers batteries many times faster than an alternator.

• Wide Operating Range

  Vehicle voltage input from 11 – 32 Volt, Solar input is from 9 – 42 Volt and DC input (40amp only) 11 – 32 Volt.

• Temperature Compensation

  Using the temperature sensor, the charger continually adjusts its charge rate to suit the battery temperature protecting the battery from overcharging and overheating.

• Super Quiet Operation

  No internal fan ensures a super quiet operation.

• Parallel Connection Units

  Can be connected in parallel to provide more output when using high output alternators.

Protection

Reverse Polarity

• Detects reversed connection on the input or output terminals preventing internal damage

Built In Battery Isolator

• Isolates the main and auxiliary batteries at preset parameters preventing the main battery from being drained by the accessories connected to the auxiliary battery

Spark Free

• Will not begin charging unless the load is securely fastened, preventing output leads from sparking due to an accidental short circuit

Versatile Installation

• IP67 Rating, sealed against dust and water ingress. Safe to operate in -20°C to 85°C temperatures
