The New Fromeco Wolverine Switch will change the way you approach your
The Wolverine is: 2 solid-state 'fail-safe' style
Switches, 2 Battery Check Jacks, and advanced battery redundancy (sharing)
circuitry... all incorporated into one convenient package.
Measuring just 63mm or 2.5" from mounting hole to mounting hole, the
Wolverine is only three-fourths the length of two JR-style mechanical switches
placed end-to-end. At .6oz or 17grams it is also considerably lighter as
The Wolverine has 2 battery inputs, and can be used with any battery type
with a voltage up to 10VDC. Each Battery input feeds its own "FailSafe"
type switch circuit, the same kind used for Fromeco's Badger Switch. Each
Switch circuit is rated at 15amps, and is completely independent of the
other. Power then flows to Fromeco's power sharing circuits, which are
also completely redundant. You can custom-configure your Wolverine with up
to 3 outputs.
The Wolverine was developed to alleviate the problem of unbalanced regulators
creating an unequal draw upon the batteries†.
Fromeco felt that a single-circuit-board-twin-switch solution with built-in
sharing is an elegant solution... rather than having to plug in more stuff
between the battery and regulator.
†Regulators still must be reasonably balanced in systems
using twin regulators. This is to make sure one of them is not working a
great deal harder than the other.
The Wolverine can be used with any battery that is lower than 10 volts when
fully charged. NiCad and NiMH, as well as Li-ion, Li-Poly, and A123 or
LiFePO4 , work well with the Wolverine Switch system.
The Wolverine will let you use different sized batteries in the same system,
e.g., a 35% plane could be outfitted with a 4800mA-h and a 2400mA-h powering the
receiver if needed, and the batteries would work together in unison.
It is true that the Wolverine is larger than a single Standard JR™ Heavy duty
switch, yet it is smaller and lighter (17g) than the 2 HD switches that it
replaces. Also, as a single unit, installation is cleaner and easier.
