Delta frequency converters are available in various configurations. The configuration chosen by customers depends on the functionalities and features desired.
The following are common delta frequency converters available on Delta Electronics's official page. Additional information, such as specs and possible applications for each type, is outlined below the types.
This delta converter type accepts a single-phase input and generates a three-phase output. Many customers employ such converters as small machine tools and HVAC (heating, ventilation, and air conditioning) systems.
This delta frequency converter accepts a direct current (DC) input and generates an alternating current (AC) output. Customers with battery backups and renewable energy sources use this converter type. They utilize the device to power three-phase machines.
Static frequency converters are specific electrical equipment that converts frequency and voltage between alternating current sources. Customers who require high precision and stable output use this converter type. These customers typically operate delta frequency converters in sensitive equipment.
A bidirectional delta converter transfers power between two electric systems and features a storage element such as a battery. These converter types are often used in energy storage systems for grid applications.
Delta frequency converters are used in a wide range of industries. After all, they control motor speed and help to adjust system frequencies. Besides that, these converters are also employed for the following.
Pumps and fans are some of the most common applications of delta frequency converters in industrial settings. These converters help change the speed and, in the process, help save energy and improve the cooling and ventilation systems.
Customer typically uses Delta frequency converters to control spindle speed. The frequency converters do this by changing the output frequency and voltage of the electric motor driving the spindle.
In the textile industry, delta frequency converters drive motors in weaving machines, looms, and other equipment. These frequency converters allow the adjustment of motor speed to match the requirements of various textile production processes.
Delta frequency converters ensure smooth and adjustable speed of the elevators and escalators. Furthermore, Delta frequency converters for elevators enhance energy efficiency without compromising performance.
Frequent Converter Power supply has become an essential device for air-conditioning systems, turbines, and industrial chillers. Overall, Delta frequency converters ensure that these systems get the proper output voltage and frequency.
Delta frequency converters are used in marine systems, from engines to winches. These converters also ensure ships can operate on different power supplies, thus improving energy efficiency.
Delta frequency converters initiate smooth acceleration and deceleration of electric locomotives. Additionally, they also enable train systems to utilize various available frequency power sources. This versatility of frequency converters helps enhance energy efficiency in rail transport systems.
Delta frequency converters typically have specifications that revolve around the frequency range of the intended application and the voltage range for the motor. Other key features often found in delta converters include power rating, programmable parameters, and output waveform quality.
Technical specifications
Delta frequency converters are made with the following specifications. A detailed breakdown of these specifications follows after this list.
The typical input voltage of delta frequency converters is between 200V - 600V. The output voltage is also within this range. The frequency range is usually explicit frequency for voltage. However, there are models with a range of up to 50/60Hz. In terms of power output, these converters can output 0.4kW to 1,700kW. The operating temperature range of delta frequency converters is typically -10 - 60°C.
Delta frequency converters often feature IP rating housings. The common ones are IP20 - IP66. The only parameter adjustable in these converters is the output frequency. Percentage values vary depending on the machine and environment.
The typical control methods for these frequency converters are V/f control, vector control, and slip compensation. Delta frequency converters also have communication protocol compatibility with Modbus, CANbus, and Ethernet.
Selecting the suitable delta frequency converter for customers means considering several factors. Here are some of the key factors.
It is vital that the input voltage of the frequency converters matches the power supply. The power output should also correspond to the motor's power requirement.
Customer needs can also determine the control method of the delta frequency converters used. Application that requires high-precision speed control should rely on vector control. On the other hand, V/f control will suffice for basic applications.
Consider the operating conditions of the intended environment. Go for converters with higher IP (Ingress Protection) ratings in harsher environments.
Ensure the delta frequency converter has communication standards compatible with existing systems. Doing so will allow for easy integration and efficient control.
Some delta frequency converters come equipped with additional features. These features include built-in braking, harmonics, and energy saving filters. These additional features can enhance the converter's functionality and improve operational efficiency.
A1.Static frequency converters are used for grid applications. They stand out for their compact size and high reliability. On the other hand, dynamic frequency converters are used for high-power applications. They are known for their high efficiency and bidirectional power flow capability.
A2.The first way to ensure customers' safety is by adhering to the manufacturer's safety recommendations and instructions. Additionally, using appropriate protective measures, such as fuses and circuit breakers, helps prevent damage during the operation. Finally, connecting a qualified professional to handle the installation is recommended.
A3.Most delta frequency converters have a frequency limit of up to 50/60Hz. But frequency generators can go as high as 400Hz, depending on the application.
A4.Yes, delta frequency converters can power various renewable energy systems. These systems include wind and solar energy systems. They achieve this by converting the renewable energy system's DC or varying AC input into a stable three-phase output.
A5.Delta frequency converters are made from various durable materials. The materials include metals like aluminum and steel and high-strength plastics. The choice of materials used depends on the frequent converter environment, as one has to ensure they withstand humidity, heat, and dust.
