When Reynolds battery protection technology a genuine official website, the inverter output short-circuit and overvoltage protection when the inverter output voltage feedback signal is continuous sine wave 64ms no zero-crossing signal, regarded as the inverter output short circuit, UPS shutdown and alarm output; when inverse continuous time-varying output voltage is lower than 160V or higher than 80ms 280V, regarded as the inverter output over-voltage, UPS to bypass immediately and the police. 2, output current limiting protection circuit to detect the inverter output current value, when it exceeds 3.6 times the rated current limiting protection circuit immediately shut down PWM, only when the output current value is less than 3.6 times the rated value, PWM only back to work. 3, BUS BUS voltage over-voltage protection when the absolute value of continuous 64ms exceeds 440V, UPS implemented BUS over-voltage protection, into the bypass and alarm. 4, battery overvoltage and undervoltage protection when each battery voltage is higher than 15V, regarded as a battery overvoltage, UPS battery inverter automatically transferred to the state, the battery voltage drops to 13.5V after each, UPS back to the original working condition. Mains abnormal, UPS into battery inverter, the battery begins to discharge, CPU control the buzzer beeps once 4 seconds; when the battery voltage drops to 11V each time, CPU control the buzzer sounds once per second; when each battery When the voltage drops to 10V, UPS automatic shutdown. When utility power is restored to normal, UPS will automatically restart. 5. If the UPS load protection from the bypass into the inverter output before, to detect the load exceeds 110%, UPS can not turn the inverter output, CPU control the buzzer once every 0.5 seconds; if the boot load to the 110% ~ 130%, CPU control the buzzer once every 0.5 seconds, UPS into bypass after 10 seconds; if the boot load is applied to more than 130%, UPS will be immediately transferred to the bypass. Although a wide range of UPS, but the basic principles of control and protection technology is roughly the same, we would like to be able to develop more advanced UPS. Lennox long life battery grid and unique alloy formula designed to effectively resist plate corrosion; excellent large current discharge characteristics, fast and reliable charging performance, excellent deep discharge recovery capabilities to ensure the battery life. Float design life of up to 6 years. Reynolds minimal battery self-discharge current of high-quality high-purity material design, self-discharge current is very small, the capacity loss caused by the self-discharge is less than 4% per month, reducing maintenance work when the battery storage customers. Wide operating temperature range the battery can operate in a wider range of operating temperature -20 ℃ ~ + 50 ℃ even, the battery internal resistance much smaller than the conventional battery, in the temperature range -20 ℃ ~ + 50 ℃ be large current discharge, the output power is higher than with traditional opening battery specifications. Good batch consistency leading design technology and 100% airtight, voltage, capacity and safety tests to ensure that the mass production of the battery has a good consistency, particularly suitable for batteries used in tandem need more occasions, such as UPS power back-up batteries, inverters and other back-up battery pack.
