Power relays serve a variety of applications, particularly where high amperage, current control, and/or isolation is needed. HC3-H-DC110V power relays are a type of relay for over 2 amps, providing multiple features for a wide range of applications. This article will explain the HC3-H-DC110V application field and working principle.

Applications

The HC3-H-DC110V power relay is suitable for outdoor applications where a line-side voltage of 110 VDC is available. It can be used for DC motor control, DC generator control, DC actuator control, DC welding control, DC HVAC control, and DC lighting control. It can also be used to control contactors, solenoids, DC power supplies, and DC power relay circuits. This power relay can be used in a wide variety of DC applications.

The HC3-H-DC110V power relay is designed for long-term reliability in a wide range of ambient temperatures, and is especially suitable for applications where the environment temperature is likely to be higher than 110°F (43°C). It has a contact rating of 10A and a thermal current rating of 30A. The contacts are built with AgNi (silver/nickel) materials, and its contact life is up to 50,000 cycles. The power relay is UL listed, UL 508 certified, and meets VDE requirements.

The HC3-H-DC110V power relay comes with a High Surge Resistance (HRS) feature that helps protect the contact from damage caused by electrical surges. It also has an LED status indicator to help easily identify power status, and a lighted operating handle for easy use in dark locations. The relay also includes an internal diode to help protect it from current spikes, and an overcurrent protection of 500V.

Working Principle

The HC3-H-DC110V power relay consists of an electromagnet, a set of contacts, and an armature. When voltage is applied to the electromagnet, it produces a magnetic field which acts on the metal armature. The armature is spring loaded and, when moved, it closes the contacts. This creates an electrical circuit which allows the controlled DC circuit to be turned on and off. The armature also provides an electrical path between the power source and the load, and provides insulation between the two.

The HC3-H-DC110V power relay is designed so that the contacts snap open and closed when the coil is energized. The contacts are designed to handle high current applications while providing a reliable connection between the power source and the load. The contacts can be adjusted to change the power delivery through the relay, and the contacts can be used to control a wide variety of DC circuits.

The HC3-H-DC110V power relay is designed to provide reliable operation in a range of applications. It is designed to be durable and will last for many years in demanding DC applications. With its wide range of features, it is a flexible and versatile choice for control of DC circuits.
