FEATURES/BENEFITS

The package contains four solid-state relays that can be controlled independently. These relays meet industry standards and can be utilized for various applications.

• Tight zero-cross window for low EMI

• Constant current input for low current draw

• Faston terminals

• High-power switching

The control circuit is completely shielded from load transients through the use of optical isolation, ensuring complete protection.

• Industrial and process controls, including heating and motor control, facilitate efficient operation in AC equipment. The controls enable on/off functionality for smooth functioning and optimal performance.

• UL recognized (UL File Number: E128555)

Description

Operating Voltage (47-63Hz) [VRMS]：24-280

Transient Overvoltage [Vpk]：550

The off-state leakage current at rated voltage is limited to 10 mArms, as per the specifications provided. To convey the same message in a different way, we can rephrase it as follows: The maximum allowed off-state leakage current at the rated voltage is 10 milli-amps root mean square.

The minimum off-state dv/dt at the maximum rated voltage is 200 V/µsec. This value represents the highest rate of change of voltage that can occur when the device is in the off-state. It is an important parameter to consider as it ensures the reliable performance of the device when subjected to rapid voltage transients. By maintaining a minimum off-state dv/dt of 200 V/µsec, the device can effectively handle high voltage spikes and fluctuations without any damage or malfunction.

Maximum Load Current (3) [Arms]:20

Minimum Load Current [Arms]:0.15

The Maximum 1 Cycle Surge Current for Apk is 285/259 at 50/60Hz.

The rated current ensures that the maximum on-state voltage drop is limited to 1.6 Vpk.

The thermal resistance junction to case (Rjc) is specified to be 1.2 °C/W.

The fusing capability for 50/60 Hz systems is limited to a maximum 1/2 cycle I²t value of 285/259 A² sec. It is important to ensure that the fuses used in these systems are able to withstand this level of current without failure. This limit helps to protect the system from damage caused by overcurrent events. To ensure safe operation, it is critical to follow the manufacturer's recommendations for fuse selection and installation. By selecting the appropriate fuses for your system, you can ensure reliable operation even in the event of an unexpected overload.

Minimum Power Factor (with Maximum Load):0.5

GENERAL SPECIFICATIONS

GENERAL NOTE

Just a friendly reminder that all parameters listed are based on a temperature of 25°C and are per section unless otherwise specified. Additionally, the Off-State dv/dt test will be conducted using the EIA/NARM standard RS-443, paragraph 13.11.1.

Heat sinking is necessary for this package, with a maximum of 20A allowed per section and a total maximum of 60A allowed for the entire package.

The turn-on time for random turn-on versions is 0.1 msec, which means that it takes only 0.1 milliseconds for these versions to be activated. It is important to note that this time frame is incredibly fast and allows for quick initiation of the random turn-on versions.
