DC-DC Chargers

DC to DC Battery Chargers are Battery Chargers that gain there power from a DC Source such as your vehicle battery.

DC to DC Chargers are becoming more and more useful these days due to newer model car and truck alternators producing a much lower voltage then they used to, which is not suitable to charge deep cycle batteries to optimum levels.

The other commonly used scenarios are in Caravan / Campervan / Motorhome's to boost the voltage lost over long runs of cable from front of the car to the Caravan / Campervan / Motorhome's batteries. So by using a DC to DC Battery Charger you are able to boost this current to the correct voltage.




Intervolt DCC-Pro 25A DC-DC Charger

The DCC Pro was developed for the purpose of charging and maintaining any auxiliary battery in an installation where the starting battery is used as the supply source. It has been designed for use in 4WDs, RVs, buses, coaches, caravans, campers or any vehicle with a 12VDC electrical system.

The DCC Pro is built for our tough Australian conditions. Unlike many imported products, particularly those produced for the European market, it is designed to maintain output in the harshest of environments under the highest ambient temperatures.

The DCC Pro is a standalone power conversion device. It will manage a variety of different battery types according to their specific charging requirements. As no modification to the vehicle’s original wiring is required this ensures the manufacturer’s electrical system is not compromised in any way.

The DCC Pro is a highly innovative product with many unique features. It has the flexibility to adapt to almost any vehicle, old or new, simple or complex with or without an ECU controlled electrical system and even allows the operator monitor the charging status from the comfort of the cabin!

Dual Battery Systems

In a boat or vehicle with two battery banks, it is useful to be able to charge both banks while underway. Charge management devices allow two battery banks to be charged from a single source, such as an alternator, but keep batteries isolated when not charging. If one battery becomes depleted, there will be a charged bank available for emergency starting.

Blue Sea m-Series Automatic Charging Relay - 12v/24v DC 65A

Automatically combines batteries during charging, isolates batteries during engine cranking and when not charging.

The Mini Automatic Charging Relay (M-ACR) is designed to manage the charging current from alternators up to 65 Amps found on most outboards and many inboard engines.

Start Isolation (SI) protects sensitive electronics by temporarily isolating house loads from the engine circuit during engine cranking, protecting the house circuit from voltage sags and spikes.

The compact design allows for three mounting styles: surface, rear, or panel mount. The M-ACR is also available as a module in a Custom 360 Panel.

Blue Sea Add A Battery Kits - 120A & 65A

Don’t get stranded – Add a Battery!
Adding a second battery to the electrical system prevents the unintended discharge of the engine start battery.

Blue Sea Systems popular Add-A-Battery kit was primarily designed for boats with alternator output of 120A or less.

When installed, the Add-A-Battery isolates the start battery from the house loads which prevents the discharge of the start battery. The Add-A-Battery offers a simple way to control the charging and battery switching of two battery banks. The E-Series Dual Circuit Plus™ Battery Switch simplifies the switching while the SI-ACR automates charging between two batteries.

Intervolt EBI12100A Electronic Battery Isolator 12v 100A

In many vehicles, particularly 4WD or RV applications, there is a requirement to automatically charge a second (or auxiliary) battery from the starting (or main) battery. This is a well proven concept and is usually only limited by the constraints of the device used in the installation. These constraints have now been overcome by the introduction of the EBI Pro.

The EBI Pro is a revolution in dual battery control devices. Unlike conventional electro-mechanical isolators the EBI Pro is solid state. Solid state means no moving parts. There are no contacts to vibrate, chatter, arc, wear and ultimately – fail. The MOSFET based topology of the EBI Pro is proven. Reliability, durability and longevity are built in.

The solid state aspect is just the beginning. Designed on the back of the ground-breaking PSR, the EBI Pro is also adjustable in terms of voltage and time delay. This provides the installer or operator with the means to customise the EBI Pro for the application rather than suffer the ‘one size fits all’ philosophy from manufacturers of traditional devices.

Features:

We’ve already touched on the solid state, MOSFET based topology and the programmability function but there are a host of other features designed into the product which sets the EBI Pro well and truly apart from the competition.

These are expanded upon in greater detail in the manual but can be summarised as follows:

Intervolt PSR Series DC Programmable Voltage Sensing Relays - PSR12150 & PSR24150

Solid state relay technology has been around for some time. What has held it back in the extra low voltage market sector is the relatively low efficiency of Mosfet technology suitable for demanding applications in automotive, marine, alternative energy and affiliated applications.

In recent times this has changed, paving the way for Amelec's latest release, a solid state device aimed at replacing outdated electro-mechanical products. As a result we are pleased to introduce the interVOLT Programmable (Voltage) Sensing Relay.

Features:

Not only does the PSR Series feature Hi-Rel Mosfet technology but what makes it more impressive is how the technology is utilised to supercede outdated devices, especially voltage sensing versions of the same (VSRs).

In short, the PSR is a user adjustable voltage sensing relay in terms of voltage and time delay parameters. It allows the user to choose the voltage they want for switching loads on and off rather than be restricted to settings dictated by manufacturers. The time delay allows the relay to activate only after a user specified time to prevent cyclic (threshold) switching. In addition the PSR is electrically isolated (contact to load), non-polarised and bi-directional, features previously unheard of in any other solid state relay devices. Additionally the PSR has the major benefit of being able to change from normally open or normally closed all, literally, at the touch of a button!

The PSR can be used for a myriad of applications, including but not limited to:

The control icons are illuminated (flashing) when used in conjunction with the LED display and control buttons to adjust the desired parameters. Refer to operator manual for detailed information on setting the PSR parameters.

Control Connections – for control and monitoring functions

Sense Terminals – used to monitor the voltage of the desired 12 or 24 VDC supply. They are polarity conscious.
External Alarm Output – an external signal voltage for remote monitoring of the user selectable low or high voltage alarm feature.

Arrid AVC High & Low Voltage Cut Out Device

The new ARRID Auxiliary Voltage Controller (AVC) is a small yet powerful device that is used to prevent damage to low voltage appliances (including fridges, halogen globes or televisions) from both high and low voltage.

Batteries can be damaged by very low discharges, the ARRID AVC will prevent this damage by stopping the discharge of batteries below 11.8v DC ( ± 0.2v) for Starting Batteries or a model that allows deeper battery discharge of 10.8v DC (± 0.2v) for Deep Cycle Batteries. If necessary, the Bypass switch on the side of the AVC can be used to ensure that equipment may continue to run while steps are taken to recharge the battery.

Batteries can also be damaged by too high a voltage, the ARRID AVC prevents that by disconnecting DC loads when the battery voltage exceeds 15.2v DC ± 0.2v as can occur with some equalization programs on both Solar and 240v AC Battery chargers.

The ARRID AVC can be used for appliance combinations that have a maximum rating of 25 amps @ 12v DC.

The ARRID AVC features a 60 second time delay between reaching the designated cut off voltage and disconnecting the load. The AVC will not disconnect the load due to short decreases in voltage caused by the high start-up currents of inductive loads, (eg. compressor refrigerators). This feature eliminates the annoying “chatter” effect that may occur with low voltage cutouts that do not have this feature.

Voltages can be adjusted for specific requirements. For further information and specifications contact us.
