What is servo control voltage stabilizer?
The servo voltage regulator is a power supply device that uses the voltage or current signal sampled by the servo motor control circuit to drive the micro motor.
Where relay voltage stabilizer is applied to?
Industry: Breaker, knife switch, changeover switch, fuse, contactor, relay, launcher, controller, master electrical, resistor, rheostat, electromagnet, etc
Household: Air conditioners, electric fans, refrigerators, televisions, computers, projectors, printers, washing machine, induction cooker, etc
Compared with servo regulators, relay regulators are more cost-effective in the civil field
- For electrical appliances commonly used in home and office, the performance of the relay regulator is sufficient. From large electrical appliances such as air conditioners, refrigerators, and washing machines to small electrical appliances such as printers and televisions, the relay regulator can work normally; In contrast, servo regulators are commonly used in industry, medicine and other fields
- The output voltage of the relay voltage stabilizer is 220±8%, and the output voltage of the servo voltage stabilizer is 220±3%, Compared with the relay regulator, the servo regulator controls the current output more accurately.
- The relay voltage stabilizer uses more economical materials, and its working principle is simpler than that of the servo voltage stabilizer, so the relay voltage stabilizer is higher than the servo voltage stabilizer.
Which relay stabilizer is best?
This depends on the power of your appliance and the scenario you use. If you are using a voltage regulator for a household appliance, relays will suffice. If it’s industrial or medical use, you have to choose motor type.
What is the great advantage of servo motor voltage stabilizer?
- It has fast voltage regulation speed and high voltage stabilization accuracy.
- With automatic reset function, the phenomenon of high current at the moment of starting is improved.
- It has an over-voltage protection function, which effectively guarantees the safety of electrical equipment.
- Stable voltage regulation performance, high efficiency, no waveform distortion, stable voltage adjustment and other advantages.
Why is diode connected along with a relay in an automatic voltage stabilizer?
- The case where the relay needs to be connected in parallel with a diode is generally that the relay is connected to the PLC output, because when the PLC output is connected to an inductive load (such as a relay, solenoid valve), a resistance-capacitance loop or diode should be connected in parallel at both ends of the inductive load to start inhibition. Prevents the induced potential of the coil from damaging the driver or other components when switching on and off.
- To prevent the back EMF generated when the DC relay is disconnected from affecting the circuit or damaging the components, the anti-parallel diode is to provide a loop for the back EMF. This diode is called a freewheeling diode or a sink diode. Generally, when we connect the circuit, the coil and switch of the relay are connected separately (that is, connected to different branches). We can simply use a triode to control the conduction of the coil (of course others are also possible).
What are safe practices for a relay stabilizer?
- When the regulated power supply is powered on, please do not disassemble the regulated power supply or pull the input and output connections of the regulated power supply at will to prevent electric shock or other electrical safety accidents.
- The input and output wiring of the regulated power supply must be arranged reasonably to prevent trampling and abrasion, resulting in leakage accidents.
- Regulated power supply—must be grounded reliably. The user is responsible for electric shock or personal injury caused by the operation of the ungrounded wire.
- The ground wire of the regulated power supply cannot be connected to public facilities such as heating pipes, water supply pipes, gas pipes, etc., so as not to violate the rights of third parties or cause harm.
- The input and output wiring of the regulated power supply should be checked regularly to avoid loosening or falling off, thus affecting the normal use of the regulated power supply and the safety of electricity use.
- The selection of the connecting line of the voltage stabilizer must reach the connecting line that can carry enough current capacity.
- The voltage stabilizer should be handled with care and avoid severe vibration during work.
- Ensure that the carbon brush spring of the voltage stabilizer has enough pressure to avoid flashover between the contact surface of the carbon brush and the coil.
- Non-professionals, please do not disassemble the regulated power supply or repair the regulated power supply
