Product Description:
The 07.F4.SRD-3420, is made by KEB and is part of their F4 Combivert Frequency Inverters range. These inverters are designed to provide efficient and reliable solutions for 3-phase AC motor control in industrial automation. The inverter has a 220 VAC power supply, so it’s compatible with standard power systems. It’s a 50/60 Hz frequency, so it can be used globally without frequency mismatch issues, which is important for international applications and operations. The 5A current rating can handle a range of motor sizes, so it’s got plenty of power for different industrial needs. One of the main features of this inverter is the RS485 interface, which allows seamless communication with other industrial networks. This allows remote monitoring, parameter setting and integration with programmable logic controllers (PLCs), which is essential for more advanced automation. The inverter also has a DIN rail mounting design, which is great for installation in control cabinets.
The mounting method not only secures the inverter but also saves space, which is important for cramped control panels. The unit is compact, so it saves space in busy control panels while still performing well and is easy to maintain. The device can withstand harsh environmental conditions with a maximum heat sink temperature of 85°C so it can operate reliably even in high-temperature environments. This is important in industries where temperature fluctuation can be extreme and can affect electronic components. Also, the inverter has a 20A maximum permissible mains fuse, so it’s electrically safe as it protects the inverter from overcurrent situations. The 2.5 mm² line cross-section ensures proper electrical connection so it provides reliable power flow and prevents short-circuits or faults during operation.
For motor control, the inverter supports a minimum braking resistor of 56 Ω and a typical value of 100 Ω for braking applications. This allows the inverter to brake the motor efficiently so it can decelerate the machinery safely and controlled, which is important to prevent mechanical wear and ensure the safety of the machinery. The 7A maximum braking current gives more flexibility so the inverter can handle varying braking demands, thus contributing to better braking performance and motor life.
