P-Bus Battery Management Shunt SHX 648

The P-Bus Battery Management Shunt SHX 648 is designed for higher currents and powerful loads – for reliable battery monitoring even during high peak loads.

High Precision, Fine Resolution

The SHX 648 measures currents as low as 10 mA, accurately detecting even the smallest currents – with a continuous current of 600 A (short-term up to 2500 A), and an accuracy of ±0.5%.

Starter Battery Also in View

In addition to the house battery, a second SHX 648 can easily measure the starter battery, providing complete monitoring of your entire electrical system.

Galvanically Isolated (P-BUS)

The P-BUS connection is galvanically isolated. This allows for monitoring of battery banks that are separated from the main electrical system.

Easy Connection

M16 connection studs, suitable distribution busbar SAS4.
