Frequently Asked Questions

What Is A Power Relay?

A device known as a power relay uses an electromagnet to open or close a circuit when the input (coil) is activated appropriately. They offer a high level of isolation between the control signal (the coil) and the output (the contacts), and their rated impulse voltage is often in the range of 4 or 6 kilovolts.

A power relay can have change-over contacts, which are both usually open (NO) and normally closed (NC), or it could have only normally open (NO) connections. When NO contacts are the only ones offered, this typically indicates that a larger contact gap can be provided when the device is turned off, which is necessary for some applications. When switching high currents, reliable problem solvers can be found in power relays.

How Does A Power Relay Work?

An electromagnet, which consists of a coil and an iron core, an armature, a spring, and one or more pairs of contacts, is the fundamental component of a power relay’s design.

The electromagnet is activated when the contacts are set to normally open (NO), which allows a small current to flow through the input circuit. The magnetic field that is produced as a result attracts the armature, bringing the contacts closer together, thereby completing the second circuit and enabling a significant current to flow. When the power supply is cut off, the armature will no longer be attracted to it. When this happens, the spring will return the armature to its resting position, allowing the contacts to separate. This will turn off the device by preventing electricity from flowing through the second circuit.

In the case of a relay that is normally closed (NC), the direction is backward. The contacts are maintained in their closed position by the return spring. Because of this, when the input circuit is activated, the electromagnet will attract the armature. Because of this, the return spring force will be overcome, and the normally closed contacts will separate. This will prevent current from flowing through the second circuit. Consequently, NC relays always maintain the larger circuit in the “on” position.

What Is A Power Relay Used For?

A power relay employs a milliamp current to operate electromechanical switch contacts that regulate a higher current. This current is typically more than 10 Amps for power relays, making them applicable to uses requiring greater than 10 Amps.

Current power relays from Finder’s 56 Series go as low as 12 A and as high as 50 A in the 67 Series. The result is many high-quality, trustworthy solutions for end users to choose from, all of which should help their apps function at peak efficiency. Finder’s selection of power relays features some versions with bigger contact gaps than are typically used (e.g., industrial and domestic appliance controls and photovoltaic). Each model’s datasheet specifies the available contact gaps.

What is the PCB Power Relay Features?

Power relays for printed circuit boards provide higher performance in high-capacity load switching in the power supply system due to their material, which can withstand contact arc, and single-contact construction. This is because power relays are designed to switch loads of a large capacity (see figure). These power relays continue to maintain good performance in terms of both contact volume and contact pressure.

Furthermore, these power relays are in accordance with a variety of safety regulations. Relays with an increased insulation distance between coil contacts are included in the assortment of items.

What Is The Difference Between Relay And Switch?

The primary distinction between a Relay and a Switch is that the former is an electrical switch. At the same time, the latter is an electrical component that can interrupt an electrical circuit. Although most relays use an electromagnet to activate a switch mechanically, other working principles, such as solid-state relays, are also utilized in some relay designs.

Does Power Need To Be Supplied Continuously To A Relay?

No is the correct response to that question. A relay has a limited lifetime, measured in terms of the number of times it can open and close its contacts. And have a maximum capacity for the amount of current they can withstand. However, a relay’s durability is not affected by whether or not it is continuously energized.

Why Is A Relay Better Than A Switch?

Relays are a better choice for switching large currents (> 5A). Relays can change many contacts at once. Disadvantages of relays:. Relays are bulkier than transistors for switching small currents. Relays cannot switch rapidly (except reed relays); transistors can change many times per second.
