Cyrix-ct 12/24V-120A intelligent combiner
د.إ170.00The Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.
BCD 402 2 batteries 40A
د.إ150.00Diode Battery Combiners are used to guarantee continuous DC power to mission critical equipment, such as an electronic engine control system. With a Diode Battery Combiner two or more DC power sources can be used in parallel to supply the mission critical load. Failure of one source will not interrupt power to the critical load.
Argofet 100-2 Two batteries 100A
د.إ360.00Similarly to diode battery isolators, FET isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together. In contrast with diode battery isolators, FET isolators have virtually no voltage loss. Voltage drop is less than 0,02 Volt at low current and averages 0,1 Volt at higher currents.
Argodiode 80-2SC 2 batteries 80A
د.إ150.00Argodiode Battery Isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together. Discharging the accessory battery for example will not result in also discharging the starter battery. Low voltage drop due to the use of high efficiency Schottky diodes.
Lithium SuperPack 12,8V/20Ah (M5)
د.إ610.00The SuperPack batteries are extremely easy to install, not needing any additional components.
The internal switch will disconnect the battery in case of over discharge, over charge or high temperature.The batteries can be connected in parallel. Series connection is not allowed. Abuse proof :
A lead-acid battery will fail prematurely due to sulfation:
• If it operates in deficit mode during long periods of time (i.e. if the battery is rarely, or never at all, fully charged).
• If it is left partially charged or worse, fully discharged.
A Lithium-Ion battery does not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This
is a major advantage of Li-ion compared to lead-acid.
The SuperPack batteries will cut-off the charge or discharge current when the maximum ratings are exceeded.
Efficient :
In several applications (especially off-grid solar), energy efficiency can be of crucial importance.
The round-trip energy efficiency (discharge from 100 % to 0 % and back to 100 % charged) of the average lead-acid battery is 80 % .
The round-trip energy efficiency of a Li-ion battery is 92 % .
The charge process of lead-acid batteries becomes particularly inefficient when the 80 % state of charge has been reached, resulting in
efficiencies of 50 % or even less in solar systems where several days of reserve energy are required (battery operating in 70 % to 100 % charged
state).
In contrast, a Li-ion battery will still achieve 90 % efficiency even under shallow discharge conditions.
The batteries can be connected in parallel. Series connection is not allowed.
Use in upright position only.
EV Charging station
د.إ1,800.00The EV Charging Station has three phase and single-phase capabilities. It delivers maximum 22kW AC in three phase mode or 7.3kW in single phase mode.
It incorporates 4.3-inch LCD touch screen for monitoring and control.
Fully programmable RGB Light Ring around charging port, to quickly determine the device state.
It can be programmed from the web interface to display different light effects based on the current state (disconnected, charging, charged etc.). The objective is to help the user see the current state from a distance.
Galvanic Isolator VDI-16 A
د.إ420.00The galvanic isolator prevents electrolytic corrosion. It blocks low voltage DC currents that enter your boat via the shore power earth wire. These currents can cause corrosion to the boat’s underwater metals, like the hull, propeller, shaft and so on.
The galvanic isolator consists internally of two diodes which are connected in anti-parallel fashion. When they are connected in this way, the diodes allow current in both directions but only above a certain threshold voltage. The voltage at which diodes conduct is about 1.4 Vdc.
The isolator is installed directly behind your boat’s 230V connection. The forward voltage from the galvanic isolator is higher than the potential difference between metals. As a result, this voltage will not allow conduction and as such, the galvanic isolator will prevent any electrolytic current. However, if there is a (higher) error voltage in the AC circuit, the diodes will allow current through and the residual-current device will break the circuit.
Galvanic Isolator Waterproof (potted)
Maximum current 32 A
Peak current (20 ms) 3200 A

Protection category IP 67
Isolation Trans.2000W 115/230V
د.إ1,630.00Safety and prevention of galvanic corrosion
The Isolation Transformer eliminates any electrical continuity between AC shore power and the boat. It is essential for safety and eliminates the need for galvanic isolators and polarity alarms.
Safety is taken for granted in case of a normal on-shore installation. A fuse will blow or a GFCI (Ground Fault Current Interrupter) will trip in case of a short circuit or current leakage to ground. Connecting the ground wire of
the shore-side supply to the metal parts of the boat will result in galvanic corrosion (see below). Bringing only the
live and neutral wire on board results in an unsafe situation because GFCIs will not work nor will a fuse blow in
case of a short circuit to a metal part on the boat.
Galvanic corrosion occurs when two dissimilar metals in electrical contact are simultaneously exposed to an
electrically conducting fluid. Seawater and, to a lesser extent, fresh water are such fluids. In general, the more
active alloy of the couple corrodes preferentially while the less active (more noble) material is cathodically
protected. The rate of galvanic corrosion is a function of several variables including area ratios, conductivity of the
fluid, temperature, nature of the materials, etc.
It is a misunderstanding that galvanic corrosion occurs only in metal and aluminium hulls. In fact it can occur on
any boat as soon as a metallic part (the shaft and propeller) is in contact with water. Galvanic corrosion will
quickly dissolve your sacrificial anodes, and attack the shaft, propeller and other metal parts in contact with water
as soon as the boat is connected to the shore-side supply.
It might therefore be tempting not to connect the ground conductor: this is however extremely dangerous
because GFCIs will not work nor will a fuse blow in case of a short circuit to a metal part on the boat.
Blue Smart IP65 Charger 12/7(1) 230V UK Retail
د.إ400.00Features:
With up to 95% efficiency, the IP65 chargers generate up to four times less heat when compared to the industry standard. And once the battery is fully charged, power consumption reduces to 0,5 Watt, some five to ten times better than the industry standard.
Storage mode:
less corrosion of the positive plates Even the lower float charge voltage that follows the absorption period will cause grid corrosion. It is therefore essential to reduce the charge voltage even further when the battery remains connected to the charger during more than 48 hours.
Temperature compensated charging:
The optimal charge voltage of a lead-acid battery varies inversely with temperature. The Blue Power IP65 Charger measures ambient temperature during the test phase and compensates for temperature during the charge process. The temperature is measured again when the charger is in low current mode during float or storage. Special settings for a cold or hot environment are therefore not needed.
Li-ion battery mode:
The Blue Power IP65 Charger uses a specific charging algorithm for Li-ion (LiFePO₄) batteries, with automatic Li-ion under voltage protection reset.
Recovery function for fully discharged batteries:
Most reverse polarity protected chargers will not recognize, and therefore not recharge a battery which has been discharged to zero or nearly zero Volts. The Blue Power IP65 Charger however will attempt to recharge a fully discharged battery with low current and resume normal charging once sufficient voltage has developed across the battery terminals.
Functions:
Water, dust and chemical resistant
Seven step smart charge algorithm
Recovery of fully discharged ‘dead’ batteries
Automatic power supply function
Automatic compensation for high or low temperature
Several other battery life enhancing features
Low power mode to charge smaller batteries
Li-ion battery mode”
