RISH Black Shell/Flip Cover SSR-10DA/25DA/40DA/60DA/80DA/100DA/120DA Solid State Relay, DC Controlled AC

The Single-Phase Solid State Relay (SSR) is a contactless electronic switch designed to replace traditional mechanical relays. Using semiconductor technology and optocoupler isolation, it converts a low-voltage DC control signal into a high-voltage AC output, enabling sparkless, silent, and high-reliability switching. Available in DC-AC (DA), AC-AC (AA), and DC-DC (DD) versions with current ratings from 10A to 120A, it is ideal for resistive, inductive, and capacitive loads in industrial automation, temperature control systems, and household appliances.

• Control Versions:
  • DC-AC (DA): 3-32V DC control, 24-380V AC load
  • AC-AC (AA): 70-280V AC control, 24-380V AC load
  • DC-DC (DD): 3-32V DC control, 1-220V DC load

• Current Ratings: 10A / 25A / 40A / 60A / 80A / 100A / 120A

Load & Selection Guide

• Resistive Loads (Heaters, Lights): Derate by 50% (multiply operating current 2)
• Inductive Loads (Motors, Solenoids): Derate by 83% (multiply operating current 6)
• Capacitive Loads (Batteries): Derate by 90% (multiply operating current 10)
• Heat Sink Requirement: Must use a heat sink (recommended 508050mm for 10-40A models; larger heat sinks or forced air cooling for 50A+ models) to dissipate heat generated during operation.
