Constant current sources are very important in many industries including the scientific, medical, and military applications that require steady wideband AC power. They can also be used in an industrial setting to power machines and test electronic loads or in applications where a very steady level of active current is required for the effectiveness of the machine and the safety of its workers.
Different sizes to meet different needs
The default output frequency on most constant current sources is set at 60 Hz, although custom frequencies from 50 Hz to 400 Hz can be chosen to meet the customer?s unique needs. Wattage can also vary depending on the application but is most commonly 50, 100 or 200. Larger units can be specified at 400, 700 or 1000 watts to meet a variety of heavy duty industrial or serious military power needs. Any one of these units can easily provide power to highly inductive loads with little to no distortion overall. All units have very precise controls to regulate the exact output of current depending on your exact industrial, medical, or military applications.
Medical and offshore uses
Constant current power sources have many uses in the medical field including implantable pulse generators and neural stimulation systems. According to an article published in the US National Library of Medicine, 70% of patients in need of spinal cord stimulation for chronic pain or Parkinson?s disease symptoms said they preferred constant current over constant voltage power sources. In the offshore industry, it is very important to control corrosion on the surface of bridges and offshore wind turbines as well as active oil rigs to preserve their efficiency and prevent additional breakdown over time. Constant current sources are often used as a way to remove corrosion and prevent those buildups.
Heavy industrial applications
Constant voltage is a way to regulate power in which the voltage remains the same but the current can change; constant current is the opposite, the current remains the same while the voltage fluctuates. The currents required for industrial applications are usually very high and can require precise control in the power output for effectiveness. Water purification on the ultra-level requires an ion exchange known as electro-deionization which can only be achieved by precise currents. Depending on the level of purification needed this application can the adjusted to a variety of power outputs and current.
