The SSFR90B is a high-precision static frequency converter designed for a variety of applications. It is used in power grids, photovoltaic systems, industrial equipment, motors, converters, etc. and its output can be adjusted to provide precise, reliable power conditioning.

Application Fields

The SSFR90B is an ideal solution for applications requiring precise power conditioning and voltage regulation. Its output current is adjustable up to 400A. It can automatically adjust the output current to match the load. Furthermore, its output voltage can be precisely regulated even in case of varying load. With a full range of input and output voltages, the SSFR90B can be used in almost any application that requires power conditioning.

The SSFR90B can also be used for motor control and other related applications. It can be used for variable frequency drives providing precise control of induction motors. It is also used in automatic motor controllers, which can be programmed to provide precise torque or speed control. The SSFR90B is also used in renewable energy systems, such as photovoltaic systems to adjust the grid voltage from the solar panels, as well as in marine and rail applications for battery charging applications, and other applications requiring power conditioning and regulation.

Working Principle

The SSFR90B works on the principle of an arithmetic switch. This switch allows variation of output current and voltage by acting as an inverter between the input and output. It employs a digital signal processor which regulates the output voltage and current. This processor senses the load requirements and adjusts the output current accordingly. The output voltage can be set and regulated manually or with pre-set settings. This digital signal processor is also used for protection functions, such as over-voltage and under-voltage protection.

The SSFR90B is also equipped with a flyback DC-DC converter and an Output Voltage Control (OVC) circuit. The flyback converter works as an AC-DC converter that couples the input current with the output current. This is used to regulate the output voltage and to protect the output from over-voltage and under-voltage conditions. The OVC circuit limits the maximum output current of the converter. Additionally, the SSFR90B offers current, voltage, and time-delay protection in order to enhance system reliability and safety.

The SSFR90B is a cost-effective and reliable solution for a variety of applications requiring power conditioning and voltage regulation. It offers precision output current and voltage regulation in order to provide a reliable power conditioning solution. Furthermore, its flexible design makes it suitable for use in a wide range of applications.
