General (HBR1 series motor power supply) motor soft starter

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 £¦#118alue. 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)

¡ñ With 16-digit single-chip microcomputer, full digital automatic control. ¡ñ  Starting torque, current, voltage and time can be set flexibly according to different loads. ¡ñ  Provide motor with smooth and gradual starting course, reduce the impact on power grid from starting current ¡ñ  The starting current can be adjusted according to loads. ¡ñ  The character of soft stopping is helpful for prolonging the life of electric contact and satisfying the machinery     requirements on different occasions. ¡ñ  With over current protection, overload protection,phase failure protection and so on, it can preventthe motor and equipment being damaged effectively. ¡ñ  External control interface provided is convenient foruser to realize interlocking or self-control. ¡ñ  Delay the input of starting control and soft stoppingcontrol. Starting delay relay outputs, fault relay outputs. ¡ñ  Stop and operate soft stopping freely, the time of soft stopping is adjustable. ¡ñ  Novel product structure, small volume, reliable performance, convenience for installation and operation. ¡ñ The isolation of double power supply is good forprotecting control part against interference of kinds of strong electricity.

Pump  (HBR1 series motor power supply)

No water pressure fluctuation in the pipe: the soft starter can solve the problem that there is some fluctuation of water  pressure in  the pipe  when  water pump motor starts or stops, its starting current can be down to 1/3~1/4 time. Besides, the current peak £¦#118alue can be eliminated during star delta starting.

Fan  (HBR1 series motor power supply)

The belt can't skid: soft starter can prevent the belt skidding and can reduce the stress of bearing when the fan starts.

Air compressor,centerifuge,agitator (HBR1 series motor power supply)

Air compressor, centrifuge, agitator For reducing stress of machines: the soft starter can reduce the stress on gear box and driving belt when compressor, centrifuge and agitator starts.

Conveying belt (HBR1 series motor power supply)

Conveying belt The soft starter can take effect on preventing product falling down or being damaged when the conveying belt starts  or stops, and it also can reduce the belt abrasion and stress on the gear box for skidding of belt when starting, its hydraulic coupling can take the place of direct coupling.

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.
