Overview
SILE INTRUMENT horizontal HD2004W powerbasic stirrer adopts an electronic constant speed circuit. After setting the Rotation speed by adjusting the speed control button, when the load increases and the Rotation speed decreases, the speed measurement signal voltage decreases, while the given signal voltage remains unchanged. Output signal of these two signals increases after comparison of the operational amplifier, which increases the supply voltage of the motor and increases the torque, so as to keep the Rotation speed basically constant and achieve the purpose of constant speed. The device adopts deep closed-loop constant speed, which can work continuously at low speed. It is equipped with a touch switch to adjust the speed and support reverse work. Rotation speed setting has a memory function and a timing function.
Features
1. Adopt electronic constant speed circuit to ensure stable Rotation speed;
2. Deep Closed Loop Design, Constant Power at Low Speed;
3. Tap the switch to adjust the speed, easy to operate;
4. Support reversal work to adapt to different mixing needs;
5. Rotation speed setting with memory function;
6. Built-in timing function, can be set to 0-9999 minutes;
7. The overload protection function is automatically turned off;
8. Power supply voltage adaptation range (Ac100V-230V).
Principle
The powerbasic stirrer works based on an electronic constant speed circuit. When the Rotation speed is set, if the load increases and the Rotation speed decreases, the voltage of the speed measurement signal will decrease, while the given signal voltage will remain unchanged. The two signals are compared in an operational amplifier, and the Output signal increases, so that the motor supply voltage increases, increasing the torque, and maintaining the Rotation speed basically unchanged to achieve the purpose of constant speed. The constant speed adopts deep closed-loop control to ensure that constant power operation can be maintained at low speeds.
Steps
1. Pay attention to the danger of rotating the stirring head to prevent contact with the body, clothing, hair and liquid splashing;
2. Plug in the power supply and enter the standby state, press the ↑ and? keys to set the Rotation speed (change 10 revolutions per click, long press to accelerate);
3. Press the ↑ key when it stops, and then press the M key. The display screen shows -RS as reverse, + RS as forward;
4. When stopping, press and hold the M key to enter the timing setting, press the ↑ and? keys to set the time (unit minutes), and then press the M key to exit; set 0 to no timing;
5. After the overload is automatically turned off, press the M key to enter standby, and then press the M key to restart.
Notice
• It is dangerous to rotate the stirring head, pay attention to the safety of the body, clothing and hair;
• Prevent the stirring liquid from splashing out;
• Stirrer automatically shuts down when overloaded, and needs to press the M key to handle it;
• After the timing time is set, it is saved in the machine, and it is timed every time it is turned on, and it is set to 0 when no timing is required;
• Follow the steps when operating to avoid misoperation.
