Solid state relays (SSRs) are electromechanical devices that use a variety of input signals to activate a switching mechanism that can control multiple outputs. The EZ480A18 is a model of SSR that has been designed specifically with the purpose of providing reliable switching power solutions in demanding industrial applications such as HVAC, switchgear, and motor control.

The EZ480A18 is equipped with a robust aluminum-mounted base for easy installation in the field, along with a manual test button and an LED light that indicate when the device is active. This SSR has a UL recognized and CE compliant polymeric insulator material to ensure full protection against electrical surge and over-voltage. It features an excess voltage tolerance up to 400V with a continuous current rating of 18A and a thermal overload protection of 150% of rated current.

The EZ480A18 relay also comes equipped with inrush current suppression to protect the device in applications where there is an inrush occurring due to an inductive load. A built-in overheat monitoring system and open-circuit/short-circuit protection complete the set of features that the device offers. Cryptic markings are included in the device to indicate the date of manufacture and meet the UL and CE requirements.

The EZ480A18 operates on a number of different input signals such as TTL or logic levels, DC voltage, or AC voltage. The device can switch an AC or DC load with break-before-make isolation, meaning it opens the first contact before closing the second one. This can reduce the amount of contact sparking and the resulting arcing in applications where high-temperature switching is required.

The device utilizes zero-crossing technology and is triggered by a 10Vdc pulse for full AC loads while DC loads can be switched with a 5Vdc pulse. The EZ480A18 is designed to switch low order harmonics due to its switching technology and is thereby able to reach an exceptionally high level of power factor ratings.

The EZ480A18 is well-suited to operate in demanding environmental conditions, it is rated to an ambient temperature of -30°C to +70°C with a humidity level of up to 95%. Additionally, the device can be used in a variety of mounting positions including PC board, DIN rail, and panel mount. This makes the device ideal for use in a wide range of industrial applications.

In conclusion, the EZ480A18 is an advanced model of solid state relays that offers a number of benefits and protections when compared to traditional electromechanical relays. It is equipped with features that enable it to work reliably and efficiently in a variety of applications, from switchgear control to motor control. Thus, the EZ480A18 is a great addition to any industrial application.
