Product Details

The Blue Sea Systems 9230 is a precision analog meter shunt designed for accurate current measurement in DC electrical systems. This shunt provides a 50 millivolt output at 100 amperes, making it compatible with standard DC analog ammeters for monitoring electrical loads in marine, RV, and automotive applications.

Key Features:

  • 100 amp maximum rating with 50mV output for ammeter compatibility
  • Precision calibrated for accurate current measurement
  • Durable construction for marine and mobile environments
  • Recommended continuous operation at 66% of rated capacity (66 amps) for optimal longevity
  • Easy installation with standard mounting hardware

This shunt is an essential component for monitoring battery charging and discharge rates, helping you track power consumption and maintain your electrical system. The 50mV output is the industry standard for analog DC ammeters, ensuring broad compatibility with existing gauges and monitoring equipment.

Note: For continuous operation, Blue Sea Systems recommends not exceeding two-thirds (66 amps) of the rated 100 amp current under normal conditions to ensure long-term reliability and accuracy.

Easy, fast shipping and great prices!

Very nice selection,and the best prices I have seen. I would order again anytime!

Great

so far so good

I was a little concerned at first. They advertise same-day order processing, and they said my part was in stock. However, my order took three business days (plus the weekend) to finally ship. As long as the right part arrives, I'll be happy. The price was $100 less than everywhere else, so that can't be beat.

great place to find hard to find parts if they infact , do have this part I ordered ASAP

So far so good

Great information on product and fitment and low prices
