MasterShunt 500 CZone

MasterShunt is the heart of every battery powered energy system. This integrated battery monitor shares information about the battery bank with other MasterBus, CZone or NMEA 2000 enabled devices such as battery chargers, inverter/chargers and displays. No surprises: allowing complete automation of your system, MasterShunt improves comfort, prolongs battery life and extends your runtime.

The MasterShunt 500 provides all information needed for monitoring your battery bank and control of your system, such as voltage, current, state of charge and time remaining. All information is made available to the system by a single MasterBus or CZone cable. Extremely accurate measurement of current flow over state of charge enables the MasterShunt to precisely determine the time remaining.

Programmable events and an integrated real time clock make it possible to fully automate your system. Examples are to start your generator automatically when the battery bank is low (or just delaying at night!), or to automatically generate a warning at a certain depth of discharge. The proven MasterShunt design has been upgraded to obtain an even higher level of accuracy and control. Taking into account battery specific parameters, MasterShunt takes reading accuracy to a whole new level.

The MasterShunt 500 CZone allows freedom of choice with regards to fuse type, rating and location. The battery monitor is supplied with an internal bus bar, to be used in situations where an external fuse holder is selected. In case the MasterShunt is installed close to the battery, the bus bar may be replaced by either an ANL type or Class T main fuse, saving both space and cost.

Features:

  • MasterBus, CZone and NMEA 2000 communication.
  • Fits in a CZone system including setup tools and configuration file.
  • Digital shunt providing the energy system with extensive information and historical data.
  • Very accurate and reliable determination of State of Charge (SOC).
  • Service mode prevents memory loss during system maintenance.
  • Realistic and precise indication of the time remaining.
  • For higher current, multiple MasterShunt models may be installed in parallel.
  • MasterConnect system makes connecting to the DC Distribution product very easy.
  • Straight forward, easy to install.
  • Freedom of choice for fuse type, rating and location. Suitable for T-fuse and ANL-fuse (to be ordered separately).
  • Robust housing with isolation of the DC connections.

Applications:

Any application in marine, mobile, industrial, infrastructure where batteries need to be monitored for increased reliability, battery life, comfort and runtime.

A favorite in our house!
Pattern Name: Ultra Ring, Size: Large, Pattern Name: Ultra Ring, Size: Large
~ Recommend if you have a dog who: is a heavy chewer/tugger, loves to chase squirrely things (it can have a wacky roll to it, which my dog thinks is so fun), gets their toys dirty or slobbery. My pup is 65 pound pitty mix - i'd definitely say this is for big dogs. Maybe medium (45+ pounds, ish?). Just my opinion, of course... but I think it's a bit thick/heavy for small pups to grab. ~ My pup LOVES this ring toy! I got this back in October - so it has been through the ringer. Atlas isn't usually a super heavy chewer, but with this toy she is. Not only does she love to play with it, she will even bring it to her bed to comfort chew (i think she likes the pressure on her back teeth... this rubbery material is SUPER sturdy but also has a little bit of "give" so I don't worry at all about her teeth). She loves to chase it / catch it on the roll. She brings it to me on the daily for play. Its good for tug, chase, or fetch. Perfect for the beach or any environment, really, as it's super easy to clean... so it comes with us everywhere. We will probably have this toy forever... there's not a single puncture mark yet. So, for me worth the cost 10x over.

It’s Trash
Pattern Name: Tug Frisbee, Size: Large
Lasted maybe 1 minute… I gave it to my dog turned to throw away package, when I looked back dog had already taken a chunk off … might as well have given him the dollar bills it took to buy … they would probably last as long

Arguably bulletproof
Pattern Name: Tug Pull, Size: Large
All good. The gauge is slightly large which my dog, Magnum {66 lb American Stafordshire Terrier), struggles with - slightly. Not a big problem and I am thinking that if the guuge were smaller, Magnum would be able to chew through it and ruin the toy. Comfy grip. Center piece or grip works great also because Magnum likes to grip that which allows the 2 handles to be free for human pulling. Walmart has/had a similar item, but..........one end has tiny spikes meant for the dog to grip. My dog never liked that end, however, so I always got the ucomfortable knobly end and he got the smooth human end - hah ha. Too, Magnum chewed through two of these Walmart toys., I have seen Magnum chewing on this reviewed toy, but I am seeing zero damage. Walmart's toy is cheaper, but the lifetime guarantee on this Tuff Tug toy eliminartes any price advantage. Update 6 months later - the product appears to be bulletproof.....until it wasn't. Everyone on the dog park marveled at the item's amazing durability in terms of daily severe abuse AND my dog's preoccupation with gnawing on the toy. Not only does it hold up, but there are almost no discernable chew marks. All of that said, the toy did finally show some coming apart today (mid March '24 - bought Oct '23 with lots of daily chewing and tug of war abuse). Remarkably, with a good 30% of the item's thickness chewed through - it still stands up to severe and constant tug of war strain......like nothing ever happened! We joke at the dog park that tbe toy is made of Kryptonite. Yes, it's now damaged some, but I feel it is well worth the 20.00 price for the service it has delivered...

Great chew toy, poor frisbee
Pattern Name: Tug Frisbee, Size: Large
Bought the Tug Frisbee. It's a terrific chew/tug toy (I'd give it 5 stars for this), but it's a very poor frisbee (I'd give it 1 star for this). The material is really heavy, flexible and tough which is why it's such a great chew/tug toy. But this makes a very poor flyer. And the weight is concerning enough that I wouldn't throw it at our dog. We got a great toy out of this, just not a frisbee.

Great for my beautiful blue heeler
Pattern Name: Tug Frisbee, Size: Large
If you know what a Blue Heeler cattle dog can do is pretty similar to a velociraptor. She is not damaged this in any way shape or form and, really enjoys chasing it. Just simply toss it, very sturdy, simple to clean, just the right size. I have tested a lot of toys with her, she has destroyed a lot of toys, this one's pretty much indestructible.
