Since the high voltages carried in the wires are significantly greater than what is needed in-home, transformers are also used extensively in electronic products to decrease (or step-down) the supply voltage to a level suitable for the low voltage circuits they contain. The transformer also electrically isolates the end user from contact with the supply voltage. Transformers are used to increase (or step-up) voltage before transmitting electrical energy over long distances through wires. Wires have resistance which loses energy through joule heating at a rate corresponding to square of the current.
By transforming power to a higher voltage transformer enable economical transmission of power and distribution. Consequently, transformers have shaped the electricity supply industry, permitting generation to be located remotely from points of demand. All but a tiny fraction of the world's electrical power has passed through a series of transformers by the time it reaches the consumer.
Signal and audio transformers are used to couple stages of amplifiers and to match devices such as microphones and record players to the input of amplifiers. Audio transformers allowed telephone circuits to carry on a two-way conversation over a single pair of wires. A balun transformer converts a signal that is referenced to ground to a signal that has balanced voltages to ground, such as between external cables and internal circuits. Transformers made to medical grade standards isolate the users from the direct current. These are found commonly used in conjunction with hospital beds, dentist chairs, and other medical lab equipment.
Q: How to get samples?
A: You are welcome to get some samples before ordering. For sample, the estimated time is 5-7 days.
Q: How to confirm the quality of products?
A: We have responsible internal QC team to check all products before shipping. You can trust our quality is top notch. Customers are welcome to come to check their goods before submitting final payment.
Q: How is the customized design?
A: We are able to design wide kinds of applications based on the client's requirements. We can proof the original design, fix the design to meet the expectation or even design from an imagination, and then send clients the proof for confirmation before producing.
Q: Should I provide chart?
A: YES, it is good for us to know the requirements and it would save your time.
Q: Is a small order of available?
A: Yes, we offer small order. We understand the small quantity for DVT & PVT. Thus, it is flexible to schedule the production time no matter the order is regular or in rush.
