The NMP650-HHHH-10 AC/DC converters are a series of inverters from one of the leading suppliers of power converters and inverters for industrial and mission-critical applications. These converters are designed for low overload power, low noise and low ripple, and provide a high switching frequency up to 200kHz.

They are suitable for applications such as air-conditioning, refrigerator and ventilation systems, to provide a constant, reliable power source to the motor current as well as other higher voltage applications like air-conditioning and refrigeration.

These precision power supplies feature a wide input voltage range of 85-264 VAC, a wide load voltage range of 10-265 VDC, and a wide output voltage range of 0-265 VDC. They are also designed for high efficiency and low EMI with low RF noise, power ripple and output noise. The high efficiency of the converters provide up to 95 percent efficiency and a power factor greater than 0.90, providing a low heat dissipation and low cost. The low leakage current also reduces energy loss.

NMP650-HHHH-10 AC/DC converters also have built-in overvoltage and overcurrent protection, temperature-dependent power cycling, and short-circuit protection, all of which are designed to protect the load from any unnecessary damage. They are also RoHS-compliant as they are UL listed and CE certified.

In terms of working principle, the NMP650-HHHH-10 AC/DC converters work by converting the input AC voltage to the required DC voltage through the use of a full-wave bridge rectifier. The rectifier circuit converts the single phase AC input voltage into a rectified DC output. The DC output is then further filtered and regulated to the desired output voltage using a voltage regulator.

The bridge rectifier circuit consists of at least four diodes and a transformer, connected in a bridge formation. The transformer divides the input AC voltage into two halves, which are further divided amongst the four diodes. The diodes then allow the current to flow in the forward and reverse direction. This allows the current to be rectified and filtered before being regulated to the required output voltage.

The circuit also includes a voltage regulator to control the output voltage. The voltage regulator operates on the principle that when the output voltage passes above a set level, the regulator reconnects the diodes in order to reduce the current flow. This causes the output voltage to drop, thus stabilizing the output voltage to the required level. The voltage regulator can also include a control circuit to adjust the output voltage appropriately.

Overall, the NMP650-HHHH-10 AC/DC converters are designed to be reliable, efficient and cost-effective, making them the ideal choice for industrial and mission-critical applications. Their features make them a perfect choice for a wide variety of applications requiring a reliable stable power supply.
