The 819983-SF is a high-performance power entry module with integrated EMI filter and switch, designed for applications requiring both power distribution and electromagnetic interference suppression. This device features a rated current capacity of up to 10 A at 40°C, operates at 250 VAC 50/60 Hz, and supports operating frequencies from DC to 400 Hz. The module includes a high-quality 2-pole rocker switch and offers multiple configuration options including standard, safety (A-type), and medical (B-type) versions. Key electrical characteristics include leakage current of 0.31 mA (standard) or 0.07 mA (safety version) at 250 VAC/50 Hz, with capacitance values of 0.15 µF (Cx) and 2.2 nF (Cy) for standard versions. The device is commonly used in medical equipment, industrial power supplies, and consumer electronics where EMC compliance and integrated switching functionality are required.
