Electrical - Battery Isolators

Argodiode Battery Isolator 140-3AC - 3 Batteries - 140AArgodiode Battery Isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries. 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.The Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes: at low current, the voltage drop is approximately 0,3 V, and at the rated output of approximately 0,45 V. All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator. This compensates for the voltage drop over the diodes in the isolator. Simply inserting the isolator in the cabling between the alternator and the batteries will slightly reduce charge voltage. The result can be that batteries are not charged to the full 100% and age prematurely. Alternator energize input Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to a battery. Inserting a Diode or FET splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start. The new ‘AC’ diode isolators feature a special current limited energize input that will power the B+ when the engine run/stop switch is closed.Please contact your dealer for any returns, repairs or support issues related to this product.

Step-Down Butt Splices with Blue Heat Shrink - 22-18 AWG to 16-14 AWG - 500 PackIn an electrical system, there may be times when connecting one wire to multiple wires is needed. Alternatively, there may be times when connecting two different gauge wires is needed. In situations like this, users would use step-down butt splices with colored heat shrink.Heat-shrink butt splices protect against the elements in the most challenging of environments. They offer the best moisture protection available. These step-down heat-shrink butt splices have an adhesive liner. This liner provides a durable, rugged, environmentally sealed connection for wires between 18 AWG - and 14 AWG. It protects from physical abuse and abrasion, water, salt, and other corrosive compounds. Step-down butt splices join two wires to one. The colored dash on the tubing indicates the wire size for the connector, and this blue one indicates 16-14 AWG. Step-down heat-shrink butt splices are used to connect different gauge wires. They are also used to connect multiple wires of the same size. So, users could connect a 10 AWG wire to a 12 AWG wire or connect a 12 AWG wire to two 12 AWG wires. The first step is to properly strip the wires to the correct length. If users look inside the butt splice, an indentation where the wires should butt up against can be seen. Also, be careful to make sure that the butt splice and the wire insulation are touching. If not, users run the risk of weakening the connection.Next, the stripped wire is inserted into one side of the butt splice and crimped with the proper tool. This crimp bends the connector around the wire. This crimp creates a solid connection. On the other side, two wires are added. After crimping, perform the tug test to make sure the wires don't pull out. Once the wire has passed the test, apply heat to the heat shrink, working outward. Be careful not to burn the butt splice or the wire insulation. Now a durable, environmentally protected connection is created. Remember, butt splices are useful for their rapid installation and durability. Other methods of connection may not offer the same level of protection.Features: Protects terminations from water, condensation, salt spray, and corrosion Added vibration protection in rugged environments Provides strain relief Compliances: UL CSA RoHS Specifications: Shrink Ratio: Approx. 3:1 at 135 degrees C Operating Temperature: -55 degrees C - 125 degrees C Vol. Resistivity: 1015 Ohm-cm3 Dielectric Strength: 900V/mil Voltage Rating: 600V Guage (AWG): 22-18 AWG to 16-14 AWG Max.

Galvanic Isolator VDI-64A 64A Max Waterproof (Potted)The 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 120V - 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.Terminal posts are 6MM (1/4")This item is not ABYC A-28 approvedPlease contact your dealer for any returns, repairs or support issues related to this product.
