BK-控制变压器

Bk-控制变压器和普通变压器在使用上面没有多大的区别，只是用途不同。控制变压器只适用于单相电。

BK-控制变压器的用途：控制变压器用途比较广泛，可以定做升压，也可以定做降压变压器.一般适用于50-60HZ输入电压不超过500V的电路之中；一般作为机床控制电器或者是局部照明及指示灯电源之用；BK-控制变压器一般分为壳式和立式。
BK-控制变压器特点：控制变压器一般是采取隔离方式制作。

（1）   可以起到滤波抗干扰功能，可以出去三次谐波干扰功能

（2）   采用隔离变压器可以产生新的中性线，皮面由于电网中性线不良造成设备不能够正常运作。

（3）   防止非线性负载的电流畸变影响到变压器的正常工作及对电网产生的污染，起到净化电网的作用。

BK-控制变压器的使用环境：

（1）   周围空气湿度-5℃至+40℃，24小时的平均值不超过+35℃

（2）   安装海拔不超过2000米

（3）   大气相对湿度在周围的空气湿度+40℃时不差过50%在较低温度下可以有较高的的相对湿度，最湿月的平均最大湿度为90%，同事该月最低温度为+25℃，并考虑到因为温度变化发生的产品凝露。

The product is specifically for the Chinese power grid with AC servo motor does not match the required voltage and ultra-small size three-phase servo transformer. Changed the traditional coil-type transformers are bulky, heat, power, installation difficult problem; not pollute the grid, industrial control systems to solve the problem of the ideal power adapter, and the frequency transformer are fundamentally different in a qualitative leap in performance. This product uses the most cutting-edge microwave devices, three-phase full-bridge switching resonant techniques, SPWM modulation, completely eliminate EMI interference and is widely used in Mitsubishi, Yaskawa, Panasonic, Sanyo, Delta, TECO, Fuji, Hitachi, Omron, AB, Falak, Schneider, Lu Site, Bryant, Lenze,,, and all other import and domestic servo system; the capacity of the transformer from 0.5KVA to 80KVA, meet all the servo motor voltage to match.
Features: Intelligent, automatic adjustment of the servo system for the current, the output current from voltage fluctuations, so that the servo motor to play a better performance;
All components used in Germany, Japan, power modules, safe, reliable, five-year warranty, no failure rates, long life of more than two decades;
