Solenoid Drivers
Solenoid drivers are fundamental parts of many commercial and industrial systems that work with solenoids. Current and voltage regulation is the job of a solenoid driver- it must supply the right amounts of these two electrical conditions to get a solenoid to do what it is supposed to do, which is essentially a variety of electrical tasks, but most commonly in controlling key electromechanical devices such as valves, relays, and actuators.
The design of a solenoid driver that functions efficiently is truly an engineering challenge. It is necessary to consider power dissipation and the necessary panic elements, such as current regulation and protection circuits, to safe solenoid operation, not to mention multi-channel operation and key components for panic situations where a solenoid might have to disarm itself in a subsystem. Even with that, the heat dissipation must be in an acceptable range to keep the subsystem's operational efficiency at a level that justifies the expenditure, so that the panicked solenoid won't render a system just as inefficient overall.

More Information about Solenoid Drivers
Solenoid drivers are not one-size-fits-all devices. Their specifications are as varied as the applications that use them, and it's important to select a driver that's well-matched to the solenoid it will control. This means looking closely at not just the output voltage and current, but also factors like rise and fall time, duty cycle, and protections against overcurrent, overvoltage, and reverse EMF. These are not trivial issues to resolve. They get resolved, in part, by referring to the detailed application notes supplied with solenoid drivers, which allow different makes and models to be compared directly.applications.
FAQs
How is a magnetic field used when operating a solenoid driver?
A magnetic field is generated by the electric current supplied by the solenoid driver, which activates the solenoid by causing its internal plunger or core to move, enabling mechanical operations such as opening or closing a valve.
What is a Solenoid Valve?
What is a Solenoid Valve?
A solenoid valve is a device that uses an electromagnet to actuate a plunger which opens or closes a valve. Solenoid valves can vary greatly with size, inlets and outlets, and how much power they require.
How do they work?
Solenoid valves rely on electricity to energize an electromagnetic coil. When the coil is energized, it acts on the “core” of the valve, either opening or closing it. By opening or closing the valve, fluid or gas will able to flow if it is opened or stop flowing if it has been closed.
