SS-72 Time Relay Product Introduction (English)
The SS-72 time relay is a precision delay control component specifically designed for power system protection and automation applications. Utilizing static digital technology with integrated circuits, it achieves high-precision timing functions suitable for scenarios requiring accurate time grading coordination. The relay operates at three standard DC voltages (220V, 110V, and 48V), with pick-up voltage not exceeding 65% of rated value and dropout voltage no less than 50%, ensuring stable performance under variable conditions. Its key feature includes timing accuracy within 0.1% of set value plus 2ms, while maintaining power consumption below 9W for optimal energy efficiency. Contact rating reaches 50W breaking capacity in DC inductive load circuits at 250V/5A. The modular design offers multiple NO/NC contact configurations with flexible internal wiring to accommodate diverse system requirements. Encased in shock-resistant ABS housing, the device withstands ambient temperatures from -25°C to 70°C, having passed rigorous dielectric strength tests at 2000V AC without insulation failure. Ideal for substation automation and industrial control systems, this relay excels in protection applications demanding stringent timing precision. 61321
