AC DC converters are the most common type of electrical equipment used to convert AC current into DC current, either for direct use or for distributing energy. The LEP150F-36-ST is a high-efficiency, high-reliability DC-AC inverter that is widely used for powering multiple AC loads from a single DC power source. It consists of an AC input module, DC output module, control board, and a power supply with DC/AC conversion capability.

The input module of the LEP150F-36-ST is designed for operation with a single-phase AC energy source. Its rectifier unit combines two high-efficiency rectifier bridges, operating in parallel, to reduce losses in power conversion. It supports a wide range of AC input voltages, from 230 V to 480 V, allowing for flexibility in application. The rectified output is then filtered and converted to the DC voltage level required for powering the load.

The DC output module is designed to provide high-quality DC voltage for powering AC loads. It can provide up to 150 Amps of DC current in a single phase; allowing for large loads to be powered. It is also equipped with an active PFC (Power Factor Correction) circuit to reduce the peak current requirement from the AC input by improving the power factor. Moreover, the AC output voltage can be adjusted by varying the DC input voltage.

The control board of the LEP150F-36-ST functions as the brain of the device, providing various protection functions, adjustable settings, and monitored functions as per the power requirement. The PFC circuit of the control board handles functions such as soft-start, over-load, over-voltage, and over-current protection. It also allows users to monitor the temperature, voltage, and current for trouble-free operation.

Finally, the power supply with its DC/AC conversion capability ensures that the DC bus voltage provided to the output is always greater than the peak voltage of the AC load. As the ratings of the AC loads is higher than the supply voltage, the AC output voltage can be adjusted to the required level without having to change the DC bus. This feature allows the LEP150F-36-ST to provide a very stable AC output with a wide frequency range.

LEP150F-36-ST is very suitable for powering digital equipment, pumps, electric motors, facility management systems, battery chargers, and other applications that require a high-quality, reliable DC-AC inverter. It is also well-suited for a wide range of industrial and commercial applications, where space constraint and power efficiency are of utmost importance. The device is designed to be maintenance-free and highly reliable, ensuring maximum efficiency for years of trouble-free operation.
