The soft starting technology of AC squirrel-cage motor has been applied for many years in the developed country, it has successfully solved the following problems during AC motor starting: supply voltage quality affected by large starting current, high power consumption of power supply circuit, impact on mechanical equipment. HBR1 series full digital soft starter adopts advanced 16 digits single-chip microcomputer as the core to controlthyristor of high power, it has obvious functions like soft starting, current-limit starting, full voltage starting, double-ramp starting, soft starting and so on, besides, it has over current protection, overload protection, phase failure protection,etc, its all parameterscan be set automatically according to loads . Its output voltage rises as per setting regulation, to make the controlled motor get full voltage from setting value. After the starter finishes starting, it will bypass the thyristor, and let AC contactor begin to work. HBR1 series soft starter covering 5.5~500kw, is widely applied to various fields like metallurgy, petrol, chemical industry, construction, cement, mining, environmental protection and so on, it is the best new generation productinstead of star delta starter, reactor starter and auto step-down starter. |
Features(HBR1 series motor power supply) |
● With 16-digit single-chip microcomputer, full digital automatic control. ● Starting torque, current, voltage and time can be set flexibly according to different loads. ● Provide motor with smooth and gradual starting course, reduce the impact on power grid from starting current ● The starting current can be adjusted according to loads. ● The character of soft stopping is helpful for prolonging the life of electric contact and satisfying the machinery requirements on different occasions. ● With over current protection, overload protection,phase failure protection and so on, it can preventthe motor and equipment being damaged effectively. ● External control interface provided is convenient foruser to realize interlocking or self-control. ● Delay the input of starting control and soft stoppingcontrol. Starting delay relay outputs, fault relayoutputs. ● Stop and operate soft stopping freely, the time ofsoft stopping is adjustable. ● Novel product structure, small volume, reliableperformance, convenience for installation andoperation. ● The isolation of double power supply is good forprotecting control part against interference ofkinds of strong electricity. |

Common performanch(HBR1 series motor power supply) |
Common performance For reducing starting current: over high starting current will result in the falling of power grid voltage, subsequently, it causes the interference to the load of weak power grid. Soft starter can solve above problem, the area of cable and the size of fuse will get small correspondingly, so the installation cost can be reduced. Reduce starting current can be good for reducing electricity expense. |
