Description:
For industrial, military, marine, and custom automotive applications where currents often exceed 300 Amps, Perfect Switch is proud to introduce dual battery isolators capable of handling 400 Amps, 500 Amps, and 600 Amps respectfully. Perfect Switch is a sole-source provider for solid-state, MOSFET based diodes capable of these elevated levels of current. A dual rectifier has all the same outstanding performance characteristics of a single rectifier, but provides discharge protection for two batteries; two, one-way electrical valves in a single package. DC currents will flow from the alternator to the batteries, but current will not flow between the batteries during discharge. Dual rectifiers are commonly deployed in dual battery configurations where each battery may be discharged independent of the other.

A common problem with conventional "marine" or "RV" style isolators (aside from performance issues related to the obvious Voltage drop and associated heat) is dealing with an internally regulated alternator. A dedicated excitation circuit insures hassle-free integration with internally regulated alternators. Ultra-low on-resistance means devices require no heat sinking and no airflow at currents up to 600 Amps. Dual rectifiers are encapsulated in a custom ABS enclosure and are well suited for hostile environments. POWER-GATE is recommended by top battery manufacturers to insure that DC power gets to where it's needed without the excessive heat and voltage loss typified by more common, lesser performing silicon and Schottky devices.

Included on every POWER-GATE Dual Rectifier (GEN 4.0) is a violet Alternator excitation wire. When system Voltage (12 or 24 Volts respectively) is applied, the MOSFET array located between the Main battery cathode and Alternator input anode is enhanced for a period of 60 seconds. This trigger is initiated when the violet wire is momentarily connected to the engine start circuit typically tapped at the starter solenoid, or the wires leading to the starter solenoid. When triggered, the user will note a four second delay between trigger initiation and alternator excitation. The purpose of this circuit is to insure the Alternator's regulator excites at vehicle start-up. If the starter circuit is inaccessible, the device can be factory programmed for an alternate trigger like switched system Voltage from an accessory port. If an alternate trigger configuration is required, contact us and we can consult engineering to discuss your needs.

New:
New is the addition of an optional Battery Combine feature. When the Battery Combine Feature is activated, the default isolation mode is temporarily overridden and both MOSFET arrays are forced into the energized mode. This causes the batteries to combine. For example, if the main starting battery is discharged to the point where the vehicle won't crank, by pressing a mini logic-level momentary switch, the Battery Combine feature will enable the auxiliary battery to pass current to the main starting battery, at which point cranking can take place. Once the vehicle is started, release the momentary switch and POWER-GATE will default back to its full isolation mode.

NOTE: Please use caution with the Battery Combine option, as batteries of different capacity and differing Voltages can create a large current surge between the 2 batteries. We need to be especially careful with lithium-ion battery systems where it is not advisable to "combine" or parallel different lithium-ion battery banks that have either or:

Please Contact Us at Pinnacle Innovations to discuss your particular system and events that can occur when the Battery Combine Option is not used carefully.

POWER-GATE Dual Rectifiers can handle between 100 Amps and 600 Amps. We also offer Lower Power Applications: 100, 200 and 300 Amp versions in a Medium Package Dual Rectifier.
