DJ-100 Series Voltage Relay Product Introduction (English)
The DJ-100 series voltage relay is an electromagnetic instantaneous-action relay specifically designed for secondary circuit protection in power systems. It serves as a reliable starting component for both under-voltage and over-voltage protection applications. Featuring a robust electromagnetic mechanism, this relay series provides rapid response when circuit voltage reaches preset thresholds, ensuring stable operation of electrical equipment. The product offers multiple voltage setting ranges: over-voltage models cover 15-60V, 50-200V, and 100-400V, while under-voltage models support 12-48V, 40-160V, and 80-320V to accommodate diverse application scenarios. With exceptional performance characteristics, the over-voltage models achieve response times within 0.12 seconds at 1.1 times setting value, and under-voltage models respond within 0.15 seconds at 0.5 times setting value. The contact system adopts changeover configuration with 5A continuous current capacity, delivering 50W break capacity in 250V DC inductive circuits. Compact dimensions of 128×94×141mm and both front-panel or rear-panel wiring options facilitate flexible field installation. 51013
