Reliable Power Control: The Core of Stable Operations in Industrial Automation, Precision Temperature Control, and Electromechanical Systems The Mibbo SAE series of compact and micro single-phase AC solid-state relays (SSR) represents an innovative alternative to traditional electromechanical relays. Featuring a compact design, exceptional noise immunity, and industrial-grade protection, they deliver the reliable and efficient power control essential for system stability. Product Highlights 01 Dual-Mode Intelligent Triggering Zero-Crossing (Z): Suppresses inrush current, extends load life. Ideal for resistive loads (e.g., heating elements, lighting). Random Turn-On (R): Instantaneous response to control signals. Suitable for inductive loads (e.g., motors, transformers). 02 Industrial-Grade Protection Design Opto-isolation withstand voltage ≥4000VAC, effectively blocking high-voltage interference. Built-in RC snubber circuit suppresses voltage spikes. Flame-retardant housing + IP20 protection (requires protective cover SP-D12). 03 Visualization & Safety LED status indicator for rapid fault identification. Ultra-low leakage current (≤5mA) ensures complete shut-off. 04 Resilience in Harsh Environments Operating temperature range: -30℃ to +80℃. Resistant to vibration and chemical contamination. Suitable for applications like injection molding machines and outdoor fountains. Proven Applications Leveraging High Reliability & Noise Immunity: Temperature Control Systems: High/low temperature test chambers, incubators, HVAC (Zero-crossing prevents current surges). Industrial Equipment: Solenoid valves in injection molding machines (Random turn-on for instant response), elevator controllers. Inductive Load Scenarios: Motor start/stop, transformer control (RC snubber critical for protection). Energy Control: Stage lighting systems (Zero-crossing eliminates flicker during dimming; Triac ensures silent switching). Product Specifications Dimensions:The SAE series achieves a volume reduction of over 35% compared to the most common DC panel-mount SSR series on the market (standard size: 58mm × 45mm × 26mm), under equivalent specifications.
