Universal Solid State Relay DC-AC/AC-AC/DC-DC 10-100A

Single Phase Solid State Relay SSR DC-AC 3-32V DC Control 24-380V AC Output 10A/25A/40A/50A/60A/75A/80A/100A for Industrial Automation

产品核心概述

This Single-Phase Solid State Relay (SSR) is a contactless electronic switch designed to replace traditional mechanical relays, using semiconductor devices to achieve sparkless switching between input control signals and output loads. Available in DC-AC, AC-AC, and DC-DC versions, with current ratings from 10A to 100A, it provides reliable control for AC/DC loads in industrial automation, temperature control systems, and household appliances.

关键特性

• Versions: DC-AC, AC-AC, DC-DC (supporting 10A/25A/40A/50A/60A/75A/80A/100A ratings)
• Control Input: 3-32V DC (for DC-AC/DC-DC), 70-280V AC (for AC-AC)
• Load Output: 24-380V AC (for AC loads), 1-220V DC (for DC loads)
• Isolation: Photocoupler isolation between input and output circuits
• Housing: High-temperature flame-retardant plastic enclosure for enhanced safety
• Advantages: No mechanical contacts, silent operation, spark-free switching, high anti-interference, vibration-resistant, long service life

保护与应用说明

• Overheat Warning: SSR generates heat during operation, must be used with a heat sink (recommended 50×80×50mm for 10-40A models; larger heat sinks or fans for 50A+ high-power units).
• Load Compatibility: Suitable for resistive loads (heaters, lamps) and inductive loads (motors, solenoids). Derate current by 50-70% for inductive loads to ensure reliability.
• Safety Compliance: Built-in protection against short circuits and overvoltage; meets industrial standards for automation and control applications.
