P-Bus Energy Shunt SHX 300-L

The P-Bus Energy Shunt SHX 300-L is the digital current measuring shunt for installation in the negative line of a charging source or a consumer – for additional, precise energy flow detection in your P-BUS system.

High precision, fine resolution

The SHX 300-L measures as low as 10 mA, thus accurately detecting even the smallest currents – with a continuous current of 300 A (short-term up to 1500 A), with an accuracy of ±0.5%.

Galvanically isolated (P-BUS)

The P-BUS connection is galvanically isolated – this allows for clean detection of circuits that are separate from the vehicle's electrical system.

Easy connection

Connection is made via the pluggable terminal, M8 connection bolts, P-Bus connector M12-T.
