Solid State Relays (SSR) are specialized switches that are triggered by external electrical conditions to “switch on” or “switch off” an electric circuit. These reliability and durability-focused devices are used to regulate power usage, provide accurate switching time, and reduce risk of fire or electric “shocks” from traditional relays. The CWD4890PH is an innovative Solid State Relay that has been specifically designed to meet the needs of small and medium businesses.

The CWD4890PH relay is a high performance SSR that is capable of switching loads up to 90A with a single phase or split-phase. It is used for controlling different types of electrical equipment, such as electric motors, pumps, and pumps. The device has a fast response time of 0.164 ms, thanks to its built-in high-speed MOSFET transistors and fast current sensing technology. Moreover, it has an advanced power device heating protection design and low voltage transient protection, which ensure that the device remains safe and reliable.

The CWD4890PH is a single phase SSR with a maximum current rating of 90A. It is capable of switching both resistive and inductive loads with no current or voltage spikes. It also features a green LED indicator that is used to indicate power-on status. Furthermore, the device has four modes of operation, namely on-off control, pulse control, strobe control, and phase shift control.

The CWD4890PH comes with a wide range of control input voltage options ranging from 220VAC to 277VAC. It can be easily installed in any place, making it suitable for both indoor and outdoor applications. The device is turn-on/ turn-off hysteresis adjustable up to 20% which helps to reduce the power consumption. Additionally, it supports high surge current capacity for switching inductive loads, making it ideal for controlling electrical equipment with inductive start or high load current requirements.

The working principle of the CWD4890PH can be summed up as follows. A control signal is received from the external control device, which triggers the relay to switch on or off the electric circuit. This triggers the MOSFET transistors inside the device which create the necessary electric current to power the loads. The control signal is then sent to the external device which receives the result and “turns off” or “turns on” the circuit as required.

In conclusion, the CWD4890PH is a high-performance SSR that is suited for controlling a wide range of electrical equipment. It is capable of switching loads up to 90Amperes and supports high surge current capacity for switching inductive loads. The device has a fast response time and is protected by several features (including an advanced power device heating protection design) that ensure it remains reliable and safe in various applications.
