Zhufeng ACI Soft Start Control System DLT-RQ11

Product Overview:
The DTL series soft starter is a digital control device designed specifically for soft start and soft stop of various specifications of three-phase asynchronous motors, using microelectronic control technology. This product has an international leading level.It can be divided into two categories: RQ1 and RQ2 series.

Technical features:

It can be divided into two categories: RQ1 and RQ2 series

1、 The functional features of RQ1 series soft start:

1. Limit the voltage drop during startup time and reduce the peak current;

2. Soft start torque to protect transmission machinery;

3. Smooth acceleration start, smooth deceleration stop (eliminate water hammer);

4. Automatic bypass output.

5. It has multiple protection functions, such as overcurrent, overheating, phase loss, start stop, and stop protection.

2、 The functional features of RQ2 series soft start:

In addition to all the functions of the RQ1 series, it also has the following features:

1. To adapt to different loads, the RQ2 series soft start has 11 startup modes:

① Slope

② Current limiting

③ Slope+flow restriction

④ Slope+Soft Stop

⑤ Current limiting+soft stop

⑥ Slope+flow restriction+soft stop

⑦ Jumping+Slope

⑧ Sudden jump+slope+flow restriction

⑨ Jump+Slope+Soft Stop

⑩ Sudden jump+slope+flow restriction+soft stop
⑪ Jogging

2. Online operation, real-time monitoring, with comprehensive motor protection function.

① Voltage phase failure protection

② Blockage protection

③ Soft start overheat protection

④ Motor thermal overload protection

⑤ Current imbalance protection

⑥ Power supply voltage undervoltage protection

3. It can query the current of each phase and the frequency of the power grid, and display the working temperature of the soft starter in real time.

4. The start and stop of the cooling fan are controlled by temperature sensors, which can effectively reduce the failure rate of the machine.

5. Provide external keyboard and remote control device with RS485 interface, using standard Modbus industrial fieldbus protocol.
