Customer Service QQ: 2795594429 Hotline: 15258079212 Miss Qian one. Scope: BK control transformer for 500V 50-60Hz voltage to the circuit is usually used as a machine tool control lights and appliances or partial indicator of power use. BK control transformer shell structure can be divided according to type, according to the installation can be divided into vertical. III. Working conditions and installation conditions: 1. the installation site altitude of not more than 2000 m; 2. atmospheric relative humidity in the ambient air humidity + 40 ℃ not more than 50%, at lower temperatures can have a higher relative humidity, the wettest monthly average maximum humidity of 90%, while the monthly average minimum temperature of + 25 ℃, and taking into account temperature changes in the surface of the condensation product. 3. 4. place from rain and snow medium without enough to corrode metal and damage the insulation of gas and conductive dust, should be installed in no significant shake shock vibration. Usually control transformer Note ☆ before buying, a good first estimate of the total capacity of the appliance you are using and use the same margin of transformers, to ensure that no burn transformer instant start before ☆ installation, you should carefully check the data listed in the nameplate if it meets your requirements, confirmation, before installation. ☆ power work, the transformer core and coil heat, (but temperature does not exceed 80 ° C) is a normal phenomenon, if heating, beyond 80 ° C, even smoke, you should cut off the power switch, re-check the electrical capacity you are using. ☆ special transformers according to customer requirements and should provide the input voltage and output voltage. How many watts of output voltage of each power distribution control transformer order and delivery ☆ Purchase: Make sure a good product models, specifications, voltage, so as not to waste your valuable time. ☆ Shipping: control transformers due to heavy default Logistics, freight. Sale protection Powerware Powerware Electric sold control of electrical transformers from the production date within 12 months (to sell time), at the customer normal storage, maintenance, use conditions, due to product quality problems can not be During normal use, Powerware commitment to provide "Three Guarantees" service. For the following cases, provide paid services: ☆ unauthorized disassemble the product caused by the failure. ☆ because of poor working conditions and improper operation or user power system wiring problems or overload caused by the failure. ☆ damage caused by natural disasters. ☆ more than "three guarantees" service life of the product.
