Product Introduction

The Siemens Robbins A5E series high-voltage inverter adopts multi-level inverter technology, which significantly improves the performance indicators of the inverter through clever

circuit design and advanced control algorithms. Multi level inverters can output voltages of multiple levels, thereby reducing harmonic content, improving voltage utilization, reducing

switching losses, and enhancing system reliability. In addition, the A5E series frequency converter also has the following technical features:

Reduce harmonic content: Multi level output can more finely approximate the ideal sine wave shape and reduce harmonic components.

Improve voltage utilization: Output higher peak voltage under the same input voltage conditions to enhance system efficiency.

Reduce switch losses: By reducing the voltage stress of switch devices and selecting devices with lower voltage resistance, costs can be reduced and system reliability can be improved.

Improving system reliability: Redundant design increases the reliability of the system, allowing it to maintain operation even if individual switching devices fail.

Typical application scenarios

The Siemens Robbins A5E series high-voltage frequency converter is widely used in the following fields:

Thermal power generation: such as supply fans, induced draft fans, circulating water pumps, condensate pumps, feedwater pumps, mortar pumps, etc.

Water/wastewater treatment: water intake pump, distribution pump, sewage pump, etc.

Petrochemicals: fans, compressors, oil pumps, etc.

Steel: coke oven blower, converter dust removal fan, water pump, etc.

Oil and natural gas: oil extraction (including offshore) water injection pumps, oil transfer pumps, electric submersible pumps, etc.

Pulp/paper: Achieve high output at low power and pure power input without harmonic pollution.
