Understanding Low Voltage and Battery Requirements for DC Thrusters, Motors, and Solenoids

In electrical systems involving DC motors—specifically in applications like DC thrusters from Vetus—and solenoids, low voltage can lead to operational inefficiencies and even permanent damage. DC thrusters, like other motors, are particularly sensitive to voltage drops, inadequate wiring, and insufficient power supply.

Additionally, Vetus thrusters are equipped with built-in thermal protection (a thermo switch) that automatically cuts off operation if the motor gets too warm. This feature helps prevent overheating and extends the life of the motor, but it's still crucial to avoid conditions that could trigger the thermal switch, such as low voltage caused by faulty wiring or improper battery selection.

VETUS Marine Engines – Now HVO Approved
In line with sustainable boating efforts, VETUS has officially approved its D-LINE and M-LINE engines for use with HVO (Hydrotreated Vegetable Oil) – a low-carbon renewable diesel alternative. These engines can operate on 100% HVO (EN15940) or any blend with standard diesel (EN590) without requiring any modifications.

What is HVO?
HVO is a renewable diesel fuel derived from waste oils like used cooking oil or tallow. It contains low sulphur and aromatics, burns cleaner than traditional diesel, and is resistant to bacterial growth due to high oxidation stability.

Benefits of HVO Fuel
Reduces CO₂ and other emissions by up to 90%
Compatible with existing fuel systems – no changes needed
Lower soot and particulate emissions
Safe for all certified VETUS M- and D-line engines
