ADVANTAGES OF SOFT STARTER FIRE PUMP CONTROLLER
|
Low starting current during startup of motor (Around 150% of rated current), with soft gradual ramp (no current peak). |
|
Smooth soft starting and soft stopping. |
|
Significant reduction in mechanical stresses of the coupling and transmission devices (gearboxes, pulleys, gears, conveyors, etc.) during start (no torque peak). |
|
Increases motor and equipment lifetime due to the elimination of mechanical shock. |
|
Avoids the “Water Hammer” in pumps, and pressure surges, and so having longer life for pipe lines. |
|
Using power electronic semiconductors (Thyristors) to control the motor voltage at starting up and at stopping, and a built in single contactor for continuous steady operation. |
|
Connected to motor through 3 terminals, so it requires less cabling (3 cables), and easier setup and installation. |
|
Fire pump controller is rated 50 degree ambient, and soft starter unit is rated 55 degree ambient (UL Listed). |
|
Limitation of voltage drop during start up, so less rated power source is needed. |
|
Controls the variation of the firing angle of thyristor bridge generating a gradual and continuous effective voltage at its output and it is increased until the rated line voltage is reached. |
|
Gradually reduces the output voltage to a minimum value in a preset time thus providing a highly controlled and highly secure stop of the connected firefighting pump. |
