San Diego Electric Inc. HOME PRODUCTS SITE CONTENT CONTACT US TRANSFORMERS Control Type This device is used to transform or "step down" a high main circuit voltage to a lower voltage which is then used to operate, control or switching components of the main circuit. FIND OUT MORE Isolation Type Used to isolate electrical power from a source of alternating current (AC) power to some equipment or device. Protecting the equipment and end user from electrical potential shock hazards. FIND OUT MORE Step Up or Down Transformers As the name implies; these versatile transformers step voltages up or down from an AC power source. The applications they have greatly vary, to the need of the circuit use and power demand. FIND OUT MORE Buck Boost Type A buck boost transformer is a type of transformer that is used to make adjustments to the voltage applied to alternating current equipment. FIND OUT MORE Still have questions?? We want to help. However, no sales personnel here are electricians or qualified to answer technical or how to questions or what electrical codes apply. FIND OUT MORE CONTROL TRANSFORMERS Generally used for power to control circuits, lighting, Motor Starters, door bells, etc..... Control transformers have a wide range of applications. From door bells to starters, we have them from 10va (volt amps) to 1.5kva units. They are technically a step down transformer designed for lower voltage application. Other type of controls come in the form of control relays; see our Motor Control page for details about that unit. Information to have on hand when asking our staff for a product would be: 1) Input primary side voltage: 2) Output secondary side voltage: 3) The amount of current required or VA rating: 4) Do you need a fused input or output or both: 5) Will you require an enclosure and what type indoor or outdoor: 6) Have an approximate dimension of the enclosure needed: Once you have this listed out, finding one will be much quicker. You have the details of what you need? Remember, while we do our best to help; we don't guess about what you need. If you have made your list drop us a line or call us direct. CONTACT US ISOLATION TRANSFORMERS Power to Power transformers isolating the loads.... An isolation transformer is a transformer with physically separate primary and secondary windings that prevent it from transferring unwanted noise from the input circuit to the output windings. It is usually used for sensitive equipment and personal safety reasons. An excellent description of how this unit is used and works can be found on this link: http://www.powerinspired.com/isolation-transformer-need-know/ It would be helpful to know: 1) The voltage needed: 2) The amount of current required or KVA rating: Got the information? Remember, while we do our best to help; we don't guess about what you need. If you have made your list drop us a line or call us direct. CONTACT US STEP UP OR DOWN TRANSFORMERS Transformation of voltage level to match the load demand..... A transformer that increases voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up transformer. Conversely, a transformer designed to do just the opposite is called a step-down transformer. Because of this design information is required about both sides of this transformer. 1. Primary input voltage: 2. Secondary output voltage: 3. KVA (kilovolt amps of the load demand): 4. Number of electrical phases being used: 5. Indoor or Outdoor application: 6. Lug configuration if more than one wire per phase is used: Let us know what you need If you have your list ready, drop us a line or two for a stock check. Our staff will not be able to answer any technical questions beyond the specifications of the unit in stock. CONTACT US BUCK BOOST TRANSFORMER Specials needs transformer for power........ A buck–boost transformer is a type of transformer used to make adjustments to the voltage applied to alternating current equipment. Buck–boost connections are used in several places such as uninterruptible power supply (UPS) units for computers and in the tanning bed industry for example. Information we need to help is: 1. Primary input voltage: 2. Secondary output required: 3. Mounting type; wall, floor, etc.: 4. Indoor or Outdoor requirements: 5. Number of electrical phases: Lets see if we can help you out. If you have your list ready, drop us a line or two for a stock check. Our staff will not be able to answer any technical questions beyond the specifications of the unit in stock. CONTACT US STILL HAVE QUESTIONS??? If you haven't found what you need..... None of our sales staff are electricians and are unable to answer questions regarding electrical connections, specification requirements, or electrical codes that apply. You might have a need for parts though. Transformer parts are limited to rain guards, landing lugs, multiple wire lugs or grounding requirements. Make a list; we will try to assist you as best we can. Give us a shout... Have you got your list ready? Keep in mind we have numerous transformers in stock but not all; so availability may be an issue. In that case, if you have time to work with; let us know. We can provide a quote with that in mind.
