What safety protection device does Schneider apcups power supply have

Schneider apcups power supply must have a set of safety protection device in use. The safety protection device of uninterruptible power supply mainly has the following requirements:

(1) Schneider UPS power supply shall be equipped with protection device matched with protection equipment and components. There are appropriate indicators and / or alarms and other monitoring devices at appropriate positions, which can automatically or manually operate and maintain the battery power generation system within the allowable limits.

(2) The safety protection device designed and installed by Schneider UPS power  should be reliable and suitable for various environments. The installation site should meet the requirements of maintenance and test. Moreover, in the state of protection function, other functions should be distinguished from it to show the independence of protection function. In order to obtain proper and reliable protection, corresponding design principles should be followed. In particular, the design principle should include failure protection mode, redundancy design, diversity design and self diagnosis function.

(3) In the design stage of Schneider UPS power supply safety protection device, integrated measurement, regulation and control devices (such as over-current cut-off switch, temperature limiter, differential pressure switch, flowmeter, delay relay, over speed monitor or similar monitoring devices) shall be adopted to prevent dangerous overload of equipment.

(4) The design and installation of protective devices with measuring function shall be able to handle the foreseeable operation requirements and application under special conditions. Be able to check the accuracy of the readings and the suitability of the device where necessary. This kind of device can determine a comprehensive safety factor of the alarm threshold outside the safety warning line, especially considering the operating conditions of the device installation and the possible deviation in the measurement system.
