The CWA48125S solid state relay (SSR) is an electronic circuit designed to control high power electrical loads from low-level electronic circuits. The device features a zero-crossing detection circuit that can be triggered by any common logic input. The CWA48125S is capable of controlling AC loads up to 250VAC/48Amps and offers a wide range of applications, including HVAC systems and lighting controls.The most distinctive feature of the CWA48125S SSR is its zero-crossing detection circuit. This feature ensures that the device only switches on at the peak voltage. This eliminates any transients or spikes caused by the sudden application of AC power. The device also provides added protection from power cross and phase loss.The CWA48125S uses an optically isolated output stage to switch AC loads up to 250VAC/48Amps. The device has two optically isolated inputs, one that controls the switch on (output) function and one that controls the switch off (output) function. This allows the device to be used as either a pulse-width modulated (PWM) or a zero-crossing detection (ZCD) SSR.The CWA48125S has a maximum switching frequency of 100KHz. This high switching frequency makes it ideal for applications that require a high-speed switching solution. It also reduces the chances of misfiring caused by higher frequency AC signals.In addition to its zero-crossing detection circuit, the CWA48125S also features an over-temperature protection circuit that shuts down the output of the device when the internal temperature exceeds a predetermined threshold. This feature helps protect both the device and the load from excessive heat.The CWA48125S is an ideal choice for applications that require a reliable and versatile SSR. It is capable of switching AC loads up to 250VAC/48Amps with its fast switching frequency of 100KHz, and its zero-crossing detection and over-temperature protection circuits provide added reliability and protection. The device is relatively easy to install and is well-suited for many applications, including HVAC systems and lighting controls.
