Product Introduction
SSR Solid State Relay Usage Precautions
1. Load Derating: Use at 60%-70% of the rated current. Overvoltage and overcurrent operation are strictly prohibited.
2. Heat Dissipation Installation: 25A and above models must be equipped with a heat sink. Apply thermal grease to the contact surfaces.
3. Load Protection: When controlling inductive/capacitive loads, an RC snubber circuit or varistor must be installed.
4. Proper Wiring: Distinguish between input and output according to the markings. Ensure terminals are tightened securely to prevent overheating from loose connections.
5. Environmental Limitations: Avoid use in humid, highly corrosive, strongly electromagnetically interfered, or excessively hot environments.
6. Live Safety: Disassembly and repair while the circuit is energized are strictly prohibited. Immediately disconnect power and replace the faulty relay.
