Power relays are electrical control devices which allow a small amount of a power flow to control a heavy one. The DK1A-3V is a power relay model that exemplifies this application, allowing a 3-volt input to control up to 10A at 120/240 volts. The DK1A-3V can be used for applications such as lighting, motor loads, metering, and heating. Moreover, it is capable of high inrush usage and long service life.

The DK1A-3V is a single pole/single throw relay. This means it has one normally open contact with a single actuator for on/off action. It has a 3 V DC coil and has a maximum operating voltage of 132 V AC or 250 V DC. The unit’s contact closure can be made and maintained at any voltage ranging from 0 - 132 V AC or 0 - 250 V DC. The continuously rated current of the contact is 10A resistive. Therefore, this power relay surpasses the needs of over 2 amps.

The DK1A-3V works on the principle of electromechanical energy conversion, where a small electric signal is used to open or close a large circuit. When current is applied to the coil, an electromagnetic field is created which is capable of completing the circuit of an electric load. This causes the metal yoke and armature to move towards the poles. If the coil was energized, the armature will force the contact "open"; inversely, if the coil was de-energized, the contact springs will push the armature and contact "closed". In either case, the control circuit is complete, allowing for operation of the load. The DK1A-3V also features an adjustable stay-put actuator which allows for a longer service life.

As this power relay has a 3 V DC coil, it can be easily actuated by control circuits that use microprocessors and integrated circuits. The DK1A-3V is an ideal choice for applications where power needs to be switched quickly and accurately. For instance, it can be used in PLCs and monitoring systems in order to control fans, lighting, and motors. Moreover, it can be used in residential and industrial applications such as HVAC systems, air conditioning, and electrical panels.

The DK1A-3V is a quality power relay that is suited for many applications where an over 2 amp control is necessary. With its 3V DC coil, it can be easily triggered by control circuits that require precision and accuracy. The electromechanical nature of the device makes it resilient and reliable, and the adjustable stay-put actuator allows for a longer service life.
