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.

ASURION EXTENDED WARRANTIES
I was skeptical that my ASURION warranty would be honored since it was not an easy process to submit claim and required following up several times. Not as easy as buying it initially for a product on check out at amazon. Once the burdensome process was completed on my end, It was easy load the gift card issued for the warranty to my Amazon account. I would definitely look at warranty policies closer though before purchasing one. Good luck if you decide to purchase extended warranty.

Waste of Money and Time
It’s useless buying this protection plan. They will not help you with your issue. They will refer you back to the seller. What’s the point of buying a protection plan when they refuse to help? I DO NOT recommend purchasing this plan. Total waste of money and time.

Quick and easy to file a claim & get resolution!
I bought a blender from Amazon about 18 months ago and at the same time, purchased the Asurion policy to cover it. The glass pitcher cracked last week and I filed a claim with Asurion. Having never used Asurion before, I wasn't sure what to expect but I was blown away by the ease and speed with which my claim was resolved. Immediately after submitting the claim, Asurion sent a pre-paid shipping label with clear instructions on what to do next. After packing up the blender, taping the label on the front of the box (I had kept the original box the blender came in), and dropping the box off at the UPS location near me (Asurion's instructions included addresses for 2 drop-off locations in my tiny town), I had a refund in my email within hours. I was able to add the refund to my Amazon account simply by clicking on a button in the email and there it was, a credit in my Amazon account! As I said earlier, I'm blown away by how easy it was to file my claim and get a refund. Asurion made the entire process so effortless! Since the blender I had purchased is no longer available, I ordered a different one from Amazon (it arrives today - yay!) and I can guarantee you that I also purchased the Asurion policy to cover it. Thank you, Asurion, for making the process so easy and the resolution so fast.
