SPS40E DC Electric Stabilizer Actuator

Typical power consumption

 At anchor complete system (both actuators together)

Peak power per actuator: 3,6kW

Notice:
This depends on many factors, including the boat's roll period, the size of the stabilizer system for the boat, and the sea state.

When designing the power supply system, it must be able to deliver enough power for both the stabilizer system and any other connected equipment that will be operating at the same time at their maximum power draw.

Additionally, the system must handle rapid power changes from the stabilizers, which go from zero to full power twice during each roll cycle of the boat.

Once the total peak power demand is known, use the boat’s roll period and choose a typical operating scenario (e.g. large waves, medium waves, or calm conditions). Typically, small to medium waves are the most common conditions to anchor comfortably in. Then decide how long the system should run from the battery bank without running a generator.

This information allows the power system supplier to calculate the required battery capacity (in amp-hours), battery technology and charging capacity. A safety margin should be included to account for battery aging and reduced performance over time.

Note that the above listed values is for a specific sea state scenario running both actuators constantly at the stated load. Actual consumption will change according to the change in sea state such as wave height, length and frequency. These values are therefore to be considered as guidelines only.
