The EFD Single-Phase Horizontal High-Frequency Transformer manufactured by Haoer supplier is a high-frequency transformer featuring an EFD type flat magnetic core and a horizontal installation structure. Its magnetic core has the characteristics of a low profile and a wide contact surface, which is conducive to heat dissipation and reducing the overall height. The horizontal structure effectively lowers the installation height, making it suitable for compact electronic devices such as single-phase switching power supplies, adapters, LED drivers, etc., which have strict restrictions on space thickness. It has the advantages of small size, high efficiency, and good thermal performance.

Haoer is a professional manufacturer of LED driver power supply flyline high-frequency transformers. This product is a core energy conversion component specifically designed for LED driver power supplies. It is equipped with a flyline lead design to meet the compact layout requirements of the driver power supplies, while also meeting the demands for efficient energy transmission and electrical isolation in high-frequency conditions. Its operating frequency ranges from 20kHz to 500kHz, and the output power can be flexibly adapted within the range of 0.5W to 500W, capable of matching the power requirements of various levels such as household and commercial use.

The EE19 High-voltage single-phase frequency conversion transformer produced by Haoer manufacturer is a small-power high-frequency transformer using EE19 type ferrite core. It is specially designed for single-phase high-voltage frequency conversion or inverter applications. It is widely used in small-power frequency conversion drives (such as fans, pumps), photovoltaic micro-inverters, high-voltage power module and other occasions that require high-frequency and high-voltage conversion.

The Photovoltaic Solar Capacitor produced by Piner Electronics, a supplier, is a dedicated DC supporting core component for photovoltaic power electronic systems. It is specifically designed for the DC bus circuits of photovoltaic inverters, combiner boxes, and other photovoltaic equipment. It precisely meets the demanding conditions of outdoor high temperatures, voltage fluctuations, and large ripple currents in photovoltaic scenarios, ensuring the stable and efficient operation of the photovoltaic system from generation to inverter. It is suitable for the DC supporting needs of all types of photovoltaic equipment, including string-type and centralized inverters, and photovoltaic energy storage systems.

Piner Electronic’s China DC-Link Capacitor,Non-inductive winding technology is adopted, utilizing metallized polypropylene film and special metal spraying techniques. The capacitor is encapsulated in an aluminum casing, with flame-retardant epoxy resin potting for enhanced safety and durability. It features a cylindrical aluminum shell and terminals made of copper bolts or copper nuts. This design offers a compact size, high capacitance, excellent over-current capability, low temperature rise, minimal stray inductance, and extended service life, while also simplifying installation.
