Battery separator diodes

Battery separator diodes

Argofet separators allow several batteries to be charged simultaneously from a single alternator or charger, without the need to connect them together. Diode jumpers facilitate the simultaneous charging of two or more batteries from a single alternator, without the need for a connection between them. In this way, the discharge of the service battery does not affect the starter battery and vice versa. In addition, thanks to the use of highly efficient Schottky diodes, it offers a reduced voltage drop.

Unlike diode bridges, Argofet models offer the advantage of an almost imperceptible voltage loss, with a drop of less than 0.02 V at low currents and an average of 0.1 V at higher currents.

How a battery separator diode works

All models have a compensation diode which can be used to slightly increase the alternator output voltage. This compensates for the voltage drop across the diodes in the alternator bridge.
diodes.

Some alternators need a DC voltage at the B+ output to start charging, and DC current will be present when the alternator is connected directly to the battery. But if a diode bridge or FET separator is inserted, any voltage/current return from the batteries to the B+ output will be prevented, and the alternator will not be activated. The new Argodiode diode bridges have a special current limiting input that will feed the B+ output when the engine on/off switch is closed.

Benefits of battery separator diodes

• Battery insulation: They prevent one battery from discharging another when no charge is available.
• Simultaneous charging: They allow an alternator or battery charger to power several batteries at the same time.
• Protection against discharges: If one battery is completely discharged, it does not affect the others.
• Automatic management: They do not require manual intervention to control the power flow.

Installation of a battery separator diode

• The negative battery cables must be disconnected before the battery is connected.
  make modifications to the electrical system.
• Connect the positive output of the power supply (alternator) to the input of the diode bridge.
• Connect the positive connection of the battery sets to output 1, 2 and 3 (optionally) respectively.
• Connect the live flat terminal to the motor on/off switch (optional). A minimum cable cross-section of 2.5 mm² must be used.
• Connect the flat ground terminal to the negative common rail.
