Mac Plus 12/24-30 + CZone

Boost the Service Battery

Too often, service batteries don’t get the charge they need. This is a problem made worse by smart alternators and start/stop systems, which result in slow and insufficient charges. The Mac Plus DC-DC charger solves this problem, providing a quick, safe, and consistent charge to the service battery. And, by knowing when the engine is running and providing charge, users can be sure that the Mac Plus will never drain a starter battery.

Proven Mastervolt Quality

Users get peace of mind knowing that they have the best on board. Using the proven Mastervolt 3-step+ charge algorithm, the Mac Plus delivers a quick and easy charge, even for completely flat batteries.

A robust design holds up in even the harshest conditions, with battery temperature-optimized charging and a high-quality aluminum housing to ensure superior protection against dust and water ingress. The power-efficient design also allows the Mac Plus to operate silently and without a fan.

Total Power Flexibility

With a wide DC input range, the Mac Plus allows for all DC sources and can charge two batteries from a single alternator or charger. It supports a full range of chemistries and battery types, including lithium. It also functions seamlessly with modern alternators such as Euro 5 and 6, ensuring proper charging by providing constant power, even when the alternator is inactive.

Parallel configuration of up to ten units will provide over 100 amperes. Advanced high-frequency technology with modern microprocessors ensures minimal power loss when switching from 12V to 24V and vice versa.

Analog voltage sense ports are also available to compensate for voltage drops and maintain proper charging.

Superior Monitoring & Control

Compatibility with CZone®, NMEA 2000®, and MasterBus delivers truly superior monitoring and control and ensures Mac Plus integrates easily into complete systems. Achieve the best performance possible via various controllers and high-quality MOSFETs. And configure the Mac Plus with ease via MasterAdjust, the CZone configuration tool, or even via the on-board DIP switches.

Good history, but not fun, engaging in popular literature.
Format: Paperback
The author is a very competent historian, and proves her points. She does so by stating each thesis and then reciting an exceedingly long string of supporting examples. Rinse and repeat. This is high quality, academic style history, but it’s not very engaging as popular literature. No one’s going to say “I couldn’t put it down.” That being said - I liked it! I learned a lot. Thanks.

Should be required
Format: Paperback
In my opinion, this book should be required reading in high school/college history classes. It’s so important to learn accurate history when it comes to slavery and this book does that. White women played a larger role than we are taught. Please give this a read!

No regets
Format: Paperback
This was a good book to read! In school you only learn the male prospective during slavery! I know feel I can say white woman played a major role during slavery times. I like that fact that the Author put in the information to where we can go srwcah and read for ourselves. The visuals where an added touch. I feel like because alot of women of that time couldn't write so alot of information was missing. I feel like this is a must read.

One of the most poignant books I have read in a long time.
Format: Paperback
One of the most poignant books I have read in a long time. “Southern communities, lawmakers, and courts recognized slave-owning women as individuals able to acquire and exercise mastery over enslaved people, s is evident from laws passed throughout the South. Laws dating back to the colonial period routinely recognized the mistresses owned enslaved people in their own right, and these same laws acknowledged the fact that these women were capable of exercising mastery over the enslaved people they owned.” Stephanie E. Jones - Rogers. They were referred to as Southern Belles’. Revered for their ladylike daintiness. But… there was nothing dainty about their dealings for they too, owned human property. These white southern mistresses were heavily involved and often owned more property than their male counterparts even being the breadwinners. These women were barbaric and wore the crown of cruelty. Dr. Rogers gave the enslaved a voice in this text – allowing our ancestors to share with us their story and experiences under the thumb of white mistresses. This text uncovers the extent of the involvement that white women had with slave ownership. There was discord in marriages due to white women struggles to maintain control of their financial gains of human property. These women utilized the judicial system to protect their pecuniary interests. The parents of these white girls/women bequeathed slaves to white females i.e. as young as newborns – which leads us to mistresses in the making – that is the education of young white women of the mastery of slave ownership. My heart broke as I was able to envision the accounts of atrocities inflicted upon our ancestors. Our people were raped and forced into being breeders and wet nurses to ensure the livelihood of these white mistresses and their families. The evidence is insurmountable in all the ways slave-owning women invested in, and profited from their financial ties to American slavery and its marketplace. Most importantly, there was testimony from formerly enslaved people of their experiences within slavery. This text is a mandatory read for all and in my opinion, must be included as part of the curriculum in schools.

Slave Trade was not only a White Man's Affair
Format: Kindle
The book is an excellent read particularly in today's climate. Why 53% of white women would put a vile man in office is explained in the pages of this book. White women held positions of power in the America slave trade, a fact overlooked in history. These southern bell's represented as the gold standard of woman hood in the antebellum south were anything but, and they for the most part showed as much, business savvy as down right cruelty in the slave trade. They benefited in every conceivable way from this free labor market. They were no advocates for the kind humane treatment of slaves. In many cases they were as vicious as their counterpart and just as committed to a keeping Blacks marred in the system of bondage. They are in most cases depicted as silent partners and where that might be the case many white women had full command and knowledge of the value of a slave they invested in and they wanted a hefty return. In fact they used every means on the table to keep these black, men, women and children bound to their wealth creation. These co-conspirators had more than a hand in the cookie jar, they enjoyed the power and did not hesitate to support the maintenance of this inhumane institution.
