The MK3x8 is an eight channel Lithium Ion Regulator like our Mk3x4 four channel regulator.  With the change from through-hole to Surface Mount we have been able to decrease the per cell price and shrink the size from 8x4 inches to 6.9x2.4 inches with twice the channels.  It has the ability to run on as few as 4 cells and any number up to 8. The MK3x8 dissipates 2.5 amps per channel speeding up the eqaulization process.

KEY FEATURES
·Real time voltage monitoring of 4 to 8 lithium cells

·Real time temperature sensing of up to 8 external temp sensors

·Additional temperature sensor included on BMS module’s heat sink

·Small size is less than 1 inch thick and 7 inches long by 2.4 inches wide

·Quick automatic cell equalization and balancing with high and low voltage on board indicators and outputs to the charger

·Two high speed real-time warning lines which can be relay buffered for external use

·All BMS modules connect together using readily available RJ cable

·BMS easily connects to a PC using the DT USB adapter (Dongle/Terminator sold separately)

·Free Windows based scanner and command software available for download at www.manzanitamicro.com in the download section under MK3 Reg Support.

·All commands are easily entered and read in simple ASCII text

·Easy user adjustable min and max voltage parameters allow flexibility for various types of lithium cells from 1.75 to 5.5 volts per cell

·Each BMS board can bypass up to 2.5 amps equating to fast charging and equalization of unbalanced cells

·Dual RJ reg bus ports for easy connection to the charger or other BMS units in a simple daisy chain fashion

·Self regulating thermal protection and feedback to Manzanita Micro Chargers

·Built-in active variable speed 12V DC fan control output on each BMS unit. The fan settings can be viewed and changed using the software found on our website

·Large heat spreader is totally isolated from the cells and is already threaded for easy mounting to a larger heat sink.

·Each unit can dissipate up to 110 watts

The MK3x4SMT is similar to our MK3x4 but we have switched to a lower cost surface mount design to make our regulators more affordable.

The Mk3x4 Digital Rudman Regulator is a modern version of the original BATREG
Rudman charging regulator. When batteries are connected in series, even if they
are closely matched when new, over time their exact capacities and voltages will
drift apart. With flooded batteries one can charge them until the most full
batteries start gassing and then keep going until all of them equalize. The ones
which gassed can simply have more water added. With sealed lead acid
batteries like AGM or Gel types if they are overcharged they can lose electrolyte
and therefore have permanent capacity loss. The intent of the Rudman Regulator
is to bypass current around a fully charged sealed lead acid battery so that all the
other batteries in a long series string can get fully charged without any one
becoming overcharged. This is accomplished with individual circuit boards
attached to each individual 12 volt module. These boards are able to sense the
voltage across the cell and turn on a bypass resistor to bypass current around
the cell instead of going through it. The circuit has a blink feature that changes
duty cycle in response to the needs of the individual cell.
What all this means to the end user is that when using the regulators in
conjunction with an appropriate charger, one can charge and equalize the
batteries very quickly without worrying about damaging them. Fast, full charges
coupled with equalization means less down time, more range per charge, better
battery health and longer life.
The digital communication bus allows detailed continuously updating graphical
battery and BMS data display using the Manzanita Micro Touch-screen Reg
Scanner. Additionally, anyone with a PC, a USB port and the included software
can view text based important battery and regulator information. This information
includes battery voltage, battery temperature (with user installed temp sensor),
regulator heatsink temperature and other information.

The Dongle Terminator (DT) is the Digital Regulator Hardware/Software connect package. The DT is required to connect your digital regulators to a computer. With the DT you can view the voltages and temperature of your batteries on a very cool computer display.

The RROB allows interfacing between Rudman Regulators and most other chargers. It is also designed to indicate real time high and low voltages.
Main features:

• Opto-isolated high and low battery signals from the Regulators to the Charger.
• Relay outputs of the status of the high and low signals shown with yellow and blue indicator LEDs.
• The relays used are 1 amp signal relays. They use Common, Normally Closed and Normally Open Form C contacts for user supported features.
• This product requires 12 volts from a cigarette lighter to supply isolated power to the Reg Bus.
• This supports the functions of the Reg Bus even if the charger is not present, meaning that the low and high LED indicators will work without the charger connected.
• The RROB supports 2 identical RJ Reg Bus ports allowing it to be hooked up between two regulators or between the regulators and the dongle/terminator hardware connection package. This is through the DC Jack side of the box, J3 and J4.
• Charger ports are Opto buffered from the downstream Reg Bus.
