DESCRIPTION

The Trolltek™ range of DC to DC Lithium Battery chargers are ideal for onboard marine installations in harsh salt water environments. Each unit is waterproof, dustproof and shockproof ensuring they withstand the riggers of the marine world.

Installing a onboard DC/DC charger helps your lithium batteries recover while you're running at sea and can also be triggered when solar or AC chargers are connected. Keeping a DC/DC charger greatly simplifies your Lithium battery charging.

The Trolltek™ Programmable Voltage Sensitive Relay (VSR) is the ideal addition to many electrical installations and is packed with features not often seen in other basic VSRs.

A VSR is essentially a switch that can be triggered by the input voltage of a electrical circuit. It's ideal for turning devices on and off based on the supply batteries voltage. Most VSRs on the market are supplied pre-programmed with set trigger conditions that are not adjustable. VSRs are commonly used for dual battery set ups.

The Trolltek™ Programmable Voltage Sensitive Relay (VSR) is different in that it allows the user to configure their own settings for some vital parameters completely changing and improving the functionality of the VSR.

Trolltek have custom designed specific functionality into this unit to enhance the operation for targeted uses.

DESIGNED FOR LITHIUM

Trolltek™ charges 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).

Multi-stage charging gives batteries a longer life and better performance compared to traditional battery chargers.

Bulk charge stage keeps the charger at a constant current until a set voltage is reached, this typically achieves 80% of the batteries capacity in the shortest possible time.

Absorption charge stage adjusts the charge rate to bring the battery up to 100% capacity and ensuring maximum absorption.

Trolltek™ chargers include smarts and automatic technology so will not overcharge your lithium batteries and are suitable for constant connection to your battery even after full charge has been achieved.

HOW TO INCORPORATE A DC/DC CHARGER INTO YOUR INSTALLATION

Select a Trolltek™ DC/DC charger to match the Lithium battery voltage, for example, if running a 36V Lithium battery, select TTKCH3 that is designed to charge 36V batteries.

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 yellow 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.

Example, if incorporating the Trolltek™ DC/DC charger into a boat with trolling motor setup, users would typically take the input 12V power from the boat's primary starting battery as this is connected to the outboard. As the DC/DC draws power, the outboard should replenish power from the outboard charging system.

Note, the DC/DC does not monitor the supply battery voltage so has potential to draw down the starting battery voltage. To overcome this possible scenario, users can connect the yellow trigger wire to the boat engine run signal so the DC/DC is only running when the outboard is running. This works well assuming the outboard can deliver 438W of power (~36A @ 12V). Some outboards won't be able to deliver this power when the engine is idling so there is still a risk of flattening the starting battery.

The ultimate solution is to incorporate the Trolltek™ Programmable Voltage Sensing Relay into the design. The PVSR monitors the starting battery voltage and only activates the relay to deliver power to the DC/DC charger under optimal conditions that the user programs. For example, if the starting battery voltage increases to 13.2V or greater for 30 seconds, the PVRS can be programmed to automatically close its relay contacts which powers the DC/DC charger. However, if the starting battery voltage drops to 12.3V for a period of 5mins, the PVSR is programmed to open the relay contacts and turn the DC/DC charger 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 boat might be idling.
