400Hz Transformers for Medical Device
Electronic and electrical equipment with increasing frequency, would be smaller and weightless. For this reason, in some industries such as the medical industry equipment uses a frequency of 400Hz. 400Hz frequency transformers are designed and manufactured according to customer needs. Knowledge and experience of engineers, technicians, special materials and advanced production equipment are so important in these products.
Auto Transformer
In some cases, it is necessary to change the voltage, but the primary and secondary isolation of transformer are not required. In the case, Auto Transformer can be applicable. Voltage of Auto Transformer without isolation can be varied much easier than ones with isolation based on the lower weight, size, and cost. Auto Transformers are designed and manufactured according to customer`s needs.
Aviation,Railway,marine Transformer & Reactor
In aviation, rail and marine special transformers and chokes are used. Their design and manufacture should be based on the standard which is reliable in this kind of industry. Specific conditions of use of these products, make it important to accomplish standard principles. ZAFAR Industries designs and produces these products based on scientific principles. As well as the manufacture of transformers and chokes of this industry layout based on original samples are possible.
Bobbin & Coil
Bobbin and Coil used in various devices such as magnets, solenoid valves, pipe breaks diagnostic devices, medical equipment and so on being designed and produced according to customer`s requirements. high-quality raw materials and advanced Japanese and German machines play important roles in the quality of the Bobbin and Coil
Current & Voltage Transformer (CT & PT)
These transformers are useful to measure the voltage and current ratio of a system directly. These transformers reduce the voltage or current ratio of the system in order to be appropriate for voltmeter and ammeter devices. Current and voltage transformers are designed and manufactured based on customer`s needs. Also, perfect design and high quality materials have great effects on the accuracy of samplers
DC Choke
BaBased on the power of drives and inverters, DC reactors can be selected through the following tables. DC chokes that are connected to the DC bus, have the following advantages: Also DC reactors are designed and produced based on consumer`s requirement. Some of the usage of DC reactors as follows sed on the power of drives and inverters, DC reactors can be selected through the following tables. DC chokes that are connected to the DC bus, have the following advantages: Also DC reactors are designed and produced based on consumer`s requirement. Some of the usage of DC reactors as follows
- Reduction of AC input line harmonic
- Reduction of the voltage and current
- spikes Reduction of AC ripple on the DC bus
- Reduction of dv/dt & di/dt rate
- Reduction of unexpected overvoltage
- tripping Reduction of DC extra transient
- overvoltage Reduction of losses and improvement of system performance
EMC/EMI Filter
Electro magnet filters are produced in order to destroy or reduce interference of Frequency waves which had been produced by the device and are used with other devices .In the other word it Prevents transmission of high frequency harmonics to the circuit and the network. Also at the same time the voltage fluctuations in the power grid that cause damage to power supplies and other equipment to be attached to control. This kind of filter is moderate to be used in engine speed control system for frequency (drives in elevators, lifts, pumps and air conditioning systems
High Isolation Transformer
For the propose of either security or transferring energy to system having a wide range various potential, Isolation transformers are used. Rarely these transformers change the voltage, and they are just isolated. Isolation Transformers are designed and manufactured based on the customer`s needs by specifying the amount of isolation between the primary and secondary transformer and core
