What is the difference between an uninterruptible power supply and a voltage stabilizer?
When the grid voltage is normal, the UPS will supply power to the load after stabilization. At the same time, the UPS will also charge the battery in the machine as a power source. When the grid voltage is abnormal, the UPS can convert the DC power of the battery into AC power through the inverter to maintain the power supply to the load. It can be seen that the UPS can realize the automatic conversion of the grid power supply and the battery power supply to ensure uninterrupted load power supply.
As for the appropriate switching time, it depends on the application of the UPS. When used on ordinary computers, the switching time is acceptable within 10ms; when used on precision communication equipment or computer equipment, power outages are not allowed. Therefore, zero switching is required at this time. Therefore, when purchasing a UPS, you need to know the occasion where you use the UPS.
Unlike a stabilized power supply, a stabilized power supply can automatically adjust the output voltage, so that the voltage equipment with large fluctuations and non-compliant voltages is stabilized within the set range value, providing rated voltage for various electrical equipment, and ensuring that the electrical equipment works under normal voltage. It can be seen that the stabilized power supply has the following functions
1. Stabilize the voltage:
When the grid voltage fluctuates instantly, the stabilized power supply can respond quickly within 10-30ms, compensate for the voltage amplitude, and stabilize within ±2%.
2. Multifunctional comprehensive protection:
In addition to voltage stability, the voltage stabilizer can also play a protective role in overvoltage, undervoltage, phase loss, short circuit overload, etc. When a spike pulse with high amplitude and narrow pulse width appears in the power grid, the electronic components are prone to failure due to low withstand voltage, and the anti-surge components of the voltage stabilizer can play a good inhibitory role.
In addition, the voltage stabilizer also has the function of isolating conducted electromagnetic interference and lightning protection, and is widely used in data equipment. It can be seen that the difference between UPS and voltage stabilizer is still obvious. The main function of UPS is to provide power to the load. The main function of the voltage stabilizer is to stabilize the voltage so that the power supply equipment can work normally at the rated voltage. The above is the share provided by the UPS manufacturer for you. I hope it can help you.
