SANYOUC SFK-124DMP Air Conditioner Power Relay 24VDC-20A 4Pins

Description

SANYOUC SFK-124DMP Air Conditioner Power Relay 24VDC-20A 4Pins The SFK-H is a robust, high-capacity electromagnetic relay engineered for demanding switching applications in renewable energy and power backup systems. It features a 22A switching capability and is specifically designed to comply with stringent safety standards such as IEC 62109-2 for photovoltaic inverters. With a large contact gap of ≥1.8 mm, it ensures reliable isolation and arc suppression, making it suitable for high-voltage and inductive load switching. This relay is built for durability in harsh environments, offering a wide operating temperature range from -40°C to +85°C. It is RoHS compliant and carries multiple international safety certifications (UL, VDE, TUV). The SFK-H is commonly integrated into power management systems, solar inverters, uninterruptible power supplies (UPS), and industrial air conditioning units, where long electrical life and high reliability are critical. Features: High switching capacity: 22A at 250VAC. Specifically designed for PV inverters and UPS systems. Large contact gap (≥1.8 mm) for enhanced safety. RoHS compliant, environmentally friendly.
