Product Parameters
1. Features and advantages:
• Boasting an opto-isolated input stage, our relay supports TTL level-compatible inputs, and offers versatile DC or pulse triggering modes for seamless integration.
• Experience peace of mind with insulation voltage between input, output, and bottom shell exceeding 2000V, featuring safety components with CE and UL approvals.
• With no contacts or mechanical moving parts, our relay operates silently without sparks or noise, offers vibration resistance, and ensures remarkable longevity.
• Designed with precision, it features a minimal dead zone voltage and low harmonic interference (Z type), complemented by an internal RC absorption circuit.
• Delivering high performance, it accommodates an impressive AC working current of 300A, and supports a full range of working voltages from 220-380V.
• Engineered for industrial strength, it incorporates thyristor chips and premium German low thermal resistance copper-ceramic bonding (DCB) baseplates.
2. The stable and reliable performance of the product comes from excellent devices and advanced production processes
• Integrating cutting-edge DCB technology (copper-ceramic bonding substrate) for exceptional thermal management.
• A design likened to a large horse pulling a small cart, with reliable large-capacity silicon wafers for superior performance.
• Pioneering with the industry's first "thermal fatigue loading" cycle test method to ensure durability.
• Equipped with a flexible thermal pad that significantly diminishes contact thermal resistance and effectively mitigates stress.
• Proud developers of China's premier solid-state relay dynamic parameter test system, ensuring cutting-edge reliability.
Leveraging China's power module process, our high-power SSRs with a nominal current of 500A utilize the third-generation copper-ceramic bonding (DBC) technology. Whether handling inductive or resistive loads, the SSR's voltage and current resilience and reliability metrics stand at the forefront of international standards.

Note: When the current exceeds 10A, a heat sink is required. When the current exceeds 30A, a heat sink with a suitable heat dissipation area and air cooling or water cooling is required. Matching heat sinks B20~B80 are single-phase heat sinks; B140~B360 are three-phase heat sinks; B90 is a three-phase two-control heat sink.
