One. Scope:? ???? BK control transformer is suitable for 500V 50-60Hz voltage to the circuit, it is often used as a tool to 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. Three. ? 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 does not exceed + 50% 40 ℃ when, at lower temperatures can have a higher relative humidity, the wettest month of the average maximum humidity of 90%, while the monthly average minimum temperature of + 25 ℃, and taking into account the temperature change in the product surface condensation. 3. 4. place from rain and snow medium does not enough to corrode metal and damage the insulation of gas and conductive dust, should be installed in no shaking shock vibration. Order control transformer Note ☆ before buying, a good first estimate of the total electrical capacity you use, and with the same margin of transformers, transformer sure not to burn the instantaneous 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 the temperature does not exceed 80 ° C) is a normal phenomenon, if the 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. The output voltage of each power distribution how many watts control transformer ordering and delivery ☆ Order: Make sure a good product type, size, voltage, so as not to waste your valuable time. ☆ Shipping: control transformers due to heavier default Logistics, freight collect. Electrical Powerware Powerware sale protection ??? control electrical transformer products sold since the production date within 12 months (to sell time), at the customer normal storage, maintenance, use conditions, due to the product Quality problems can not normally use, Powerware promised to provide "Three Guarantees" service. For the following situations, providing paid services: ☆ unauthorized disassemble the product caused by the failure. ☆ because of poor working conditions and improper operation or user power system line problems caused by the failure or overload. ☆ damage caused by natural disasters. ☆ more than "three guarantees" service life of the product.
