RY-1224D Power Supplies - Board Mount

RY-1224D is a wide voltage input, high current, high efficiency DC DC converter. It is mainly used for voltage conversion, voltage stabilization, current limiting and voltage boosting of DC power supply systems. It adopts synchronous rectification technology, with high efficiency, high power factor, low harmonic, low ripple and wide input voltage range.

RY-1224D is mainly used in the following application fields:

• DC motors, pumps, fans and other equipment.
• Industrial control systems.
• Photovoltaic and wind power production systems.
• Electric vehicles.
• Solar and battery charging.
• Power supply systems.
• Household appliances and intelligent products.

RY-1224D adopts synchronous rectification technology, which effectively improves the product power factor and conversion efficiency. It is based on the principle of non-isolated buck-boost. It includes full-bridge rectifier, power switching transistor, feedback loop, current limit control circuit, etc. When the input voltage is high, it works as a buck, output voltage is lower than input voltage; when the input voltage is low, it works as boost, output voltage is higher than input voltage. This feature allows it to achieve wide input voltage range and high conversion efficiency.

RY-1224D takes a full-bridge rectifier as the power circuit, adopts synchronous rectifying scheme, and uses two pairs of N-channel MOS tubes to achieve synchronous rectification switching for load current. The isolated feedback loop between the controller and the rectifier is used to adjust the output voltage and current. It is designed with built-in low voltage protection, high voltage protection, over-load protection, over-temperature protection and other automatic protection functions. This ensures reliable use of the converter in various wide voltage input application fields.
