Case Study

Actuator Control DC DC ConverterDC DC converter to power fluid actuator control system

The Requirement:

The quest was for a 75W dc dc converter to replace an existing ac dc power supply within an actuator used for fluid valve control in a variety of different industries. These actuators were to be fitted in remote sites with no access to mains electricity and were to be powered from solar panels.

The Solution:

The MDSB75W conduction cooled half brick dc dc converters from Magic Power were the ideal building blocks for this requirement, along with a custom cooling plate and EMC filtering designed to withstand the demands of lightning strikes and back EMF problems associated with inductive loads. Relec Electronics are always keen to fully understand customers' requirements and will work with them to provide tailored solutions to meet specific electrical and mechanical constraints.
