Solid state relays are a type of relay that use semiconductors instead of an electromechanical mechanism. They are referred to as an SSCR or solid-state contactor. They are commonly used to switch electric signals, electrical loads, and power circuits, such as controlling motor starters, solenoids, and other equipment in industrial applications. In addition, they can provide control of an isolated signal path, switching between an active and inactive state for control purposes.

GNR45AHZ is a solid state relay designed by Shenzhen GNR Electronics Co., Ltd. It is an ultra-small form factor relay with a footprint of just 7.5mm x 9.4mm. It features a built-in zero cross and Anti-Polarization function, making it suitable for use in AC load switching applications. It has a rated operational voltage of 48V AC and can handle currents up to 200A.

The GNR45AHZ is a single-pole/single-throw (SPST) solid state relay that can switch both AC and DC loads. It is designed for applications where a small form factor and low thermal resistance are necessary. The main features of this relay include: high dielectric strength, rapid switching speed, high current capacity, and low leakage current. It is also designed with built-in short-circuit and overload protection.

The working principle of the GNR45AHZ is based on the effects of an N-channel MOSFET. The MOSFET is triggered by an input signal from the relay\'s control circuit, which causes the MOSFET gate to switch from a high state to a low state. This causes the MOSFET\'s conducting channel to open, allowing current to flow from the power source to the load. When the input signal is removed, the MOSFET gate switches to a high state, causing the conducting channel to close, and current no longer flows through the relay.

The GNR45AHZ is ideal for applications where a high current, relatively low-cost relay is needed. This is due to its high dielectric strength, rapid switching speed, and low thermal resistance. Additionally, it features a built-in zero cross function and anti-polarization protection, making it suitable for use in applications such as motor starters, solenoids, and other equipment controlled in industrial applications.
