Product Introduction

Siemens Robicon A1A252241.155S is a communication expansion board designed for Siemens Robincon inverters. The main function of this communication board is to expand the communication protocol of the inverter so that it can support more grid communication requirements.

- Universal power phase: three-phase

-- Rated voltage: three-phase AC525-690V

-- Adaptive motor power: up to 6000kW

-- Power supply voltage: high-voltage filter without filter

-- DC power supply nature: current type

-- Control mode: current vector

-- High precision: ensures accurate communication data transmission.

- Size: 280×110×10mm, easy to install and maintain.

The communication expansion board is installed on the serial communication board: it plays the role of expanding the communication protocol. Each NXGpro control system has two communication interfaces to realize network communication through different communication protocols.

Inverter Preventive Maintenance (PMA)
Inverter Preventive Maintenance (PMA) is a basic measure to improve inverter reliability, reduce maintenance and repair costs, extend the service life of the inverter, and reduce unexpected downtime. Its main measures include checking the current problems of the inverter and eliminating hidden dangers in safe operation, thereby improving the performance of the inverter, reducing the failure rate, shortening the downtime, and improving the equipment utilization.

Improve the performance of Siemens Robincon inverters
-- Assistance in inverter preventive maintenance: Inverter preventive maintenance (PMA) is essential to improving the reliability of inverters, reducing maintenance and repair costs, extending the service life and reducing unexpected downtime. Although it is not explicitly stated that A1A252241.155S is directly involved in preventive maintenance, as a component of the inverter, its normal operation helps the entire inverter system remain stable, thereby indirectly having a positive impact on the purpose of inverter preventive maintenance. For example, ensuring normal communication helps to obtain timely information about the working status of the inverter, which is convenient for preventive maintenance measures such as checking the current problems of the inverter and eliminating hidden dangers in safe operation, thereby improving and enhancing the performance of the inverter, reducing the failure rate, shortening the downtime and improving the utilization of the equipment.
