Trolltek DC/DC 48V Lithium Battery Chargers

48V LITHIUM BATTERY DC/DC CHARGER

The Trolltek™ range of DC to DC Lithium Battery chargers are ideal for a range of applications including boating and marine, caravans and RVs. Each unit is waterproof, dustproof and shockproof ensuring they withstand the riggers of the harsh Australian conditions.

Installing a onboard DC/DC charger helps your lithium batteries recover in situations where grid power isn't available. Using a DC/DC charger greatly simplifies your Lithium battery charging.

DESIGNED FOR 48V LITHIUM BATTERIES

Trolltek™ chargers are supplied configured for use with the Trolltek™ range of Lithium batteries with charge voltages pre-set to optime levels making them simple and error free for users.  Trolltek™ chargers are also compatible with many other leading brands of Lithium batteries (refer to charge specifications below to check for your application).

Trolltek DC/DC chargers work to ensure a safe charge program for both the battery as well as the upstream source such as the engine alternator by limiting the charge current.

These chargers incorporate a ACC input which means the charger is triggered to run only when the vehicle or boat engine is running. When the ACC signal is off, the charger is also 100% off and doesn't draw any power.

HOW TO INCORPORATE A DC/DC CHARGER INTO YOUR INSTALLATION

This Trolltek™ DC/DC charger is designed to work with lithium 48V batteries. Charge current is controlled ensuring a stable charge profile. The charger will also output 58V which is matched to the correct charge voltage for Trolltek 48V lithium batteries and ensures a 100% charge is achieved.

Connect power to the input cables (typically 12V) and connect the lithium battery to the output cables ready to charge. 

The DC/DC charger won't turn on until a +12V signal is supplied to the ACC input trigger wire. If the trigger wire function isn't required, connect the yellow wire to the red input wire and the DC/DC will be permanently activated.

Due to the high power draw of these chargers, it's recommended only to run the charger when there's a ACC signal from the engine indicating it's running. Users should check their engine alternator is capable of supplying enough power to maintain the DC/DC charger.

Note, the DC/DC does not monitor the supply battery voltage so has potential to draw down the supply battery voltage if the alternator isn't keeping up. In such situations, it's advised users incorporate a Trolltek™ Programmable Voltage Sensing Relay into the design.

The PVSR monitors the supply battery voltage and only activates the relay to deliver +12V to the DC/DC ACC wire under optimal conditions that the user programs. For example, if the starting battery voltage increases to 13.2V for greater for 30 seconds, the PVRS can be programmed to automatically close its relay contacts which can signal the DC/DC charger via the ACC to turn on. However, if the starting battery voltage drops to 12.3V for a period of 5mins, the PVSR is programmed to open the relay contacts which signals the DC/DC charger to turn off.  Incorporation of the PVSR eliminates the potential for the DC/DC charger accidently drawing down the starting battery whilst maximising the run time for the lithium battery charger and accommodating for periods where the engine might be idling and unable to produce adequate power. The PVSR prevents on/off cycling of the DC/DC charger which is commonly experienced with ordinary, non programmable VSR's.
