In order to ensure that the APCUPS power supply can continue to supply high-quality power to the computer even in the event of a power outage, it is important to equip the battery backup battery. When the load is not allowed to be powered, the UPS battery backup time in the communication room should be greater than the time from the mains power interruption to the rehabilitation or to the generator set is positive.

1. Don't blindly knock and bump when overhauling to avoid expansion failures, and the more you repair, the worse it gets. 2. Do not plug and unplug various control boards and plugs with electricity. Due to the strong induced electromotive force generated by plugging and unplugging the control board under the power-on condition, the instantaneous ...

1. The power supply voltage of the secondary load is 0V. There is no response after the inverter is powered on, there is no indication on the operation display panel, and the 24V and 10V voltages of the measurement and control terminals are 0V. Check that the charging resistance or pre-charging circuit of the main circuit is correct, which can be identified as a switching power supply fault. The overhaul process is as follows: 1 ...

1. AL001: overcurrent, the current value of the main 2113 circuit exceeds the motor instantaneous 5261*** high current value 1.5 times when the action is 4102. 2. AL002: overvoltage, the voltage value of the main return 1653 channel is higher than the standard value. 3. AL003: low voltage, the voltage value of the main circuit is lower than the standard.

How to carry out the selection of inverter normally, is the difficulty faced by many enterprise technical personnel and business personnel, in addition, the selection of the inverter body alone, without considering whether the inverter selection and capacity matching is appropriate, is also unscientific. ...

1. Aluminum alloy shell or steel plate welding, surface spraying; 2. Built-in inverters, circuit breakers, signal lights and other components produced by domestic or Schneider and other companies; 3. It is mainly adjusted by changing its output frequency to adjust the speed of ordinary three-phase asynchronous motor, so as to reach the production process.

1. Construction preparation. Including the preparation of operating conditions (construction skills documents and detailed planning documents), construction organization planning, equipment list, data budget, and list of machined parts; 2. Cooperate with civil engineering majors to do a good job of embedding, ...

Schneider structural circuit breaker is not stored (check the power supply of the energy storage motor, if it is normal, check whether it can be manually stored for energy) MX shunt coil live (disconnect MX coil power) The MN coil is not charged or faulty (a voltage higher than 0.85Un is applied to the MN) The circuit breaker is latched in ...

1. Overload maintenance failure: The circuit breaker should be tripped for maintenance when the current exceeds the rated current, but sometimes the overload maintenance failure may be due to some reasons. This may be due to incorrect overload maintenance settings, long overload periods, thermal aging due to successive overloads, etc. 2 ...

Take charge of the basic knowledge of UPS power supply, read the equipment manual attentively, clarify the meaning of various warning signals, warning codes, command lights, and the causes of occurrence and how to deal with them to understand the effects of various switches and buttons of the equipment. Understand the various operations in charge of UPS power supply, understand the connection connection, and understand the method of substitution ...

1. Definition of miniature circuit breaker The electrical occupation is referred to as MCB, which is suitable for communicating 50/60Hz additional voltage 230/400V, additional current to 63A line overload and short circuit maintenance, and can also be used as infrequent operation conversion of the line under normal circumstances. ...

There are many novices who are not familiar with the fake load when repairing the inverter, and the repair of the inverter saves many of their modules with the false load, because the novice repairer generally does not know how to do this, and now the light is on to make it clear that the module is going to be broken. A false load is a resistor with a few hundred ohms ( ...

1. The control accuracy of the vector type is higher than that of the general-purpose type. 2. The vector type has a large output torque at low speed, which can make the motor get a larger starting torque, which is suitable for application in the occasion of heavy load starting, such as: high-power long belt, hoist, etc. If used in some of the more common fields ...

1. Air circuit breaker is an active electrical appliance that can not only touch and disconnect the circuit normally, but also operate under abnormal conditions such as overcurrent, reverse current, short circuit and loss (under)voltage. Its primary role is to maintain the electrical equipment in the AC and DC circuits, and it can also operate the circuits infrequently. ...

Schneider miniature circuit breakers are commonly used in C65, C120, EA9, INT125 and other products. Parameter differences: N -------- breaking ability, N is 6000A, H is 10000A, L is 15kA ...

The name of a company's product was mentioned more than anyone could remember, but on the first day of the Schneider Electric North America Innovation Summit in Atlanta on Tuesday, another word appeared even more often ...

MergerWare has raised an undisclosed amount of money ahead of its Series A funding round, an executive told TechCircle. The Company provides software solutions to help integrate mergers and acquisitions-related businesses. The funding came from electrical equipment manufacturer Schneider Electric (Schneider ...

It should be basically stored in the plate, the problem is that the plate with a fully enclosed structure is large, takes up a lot of space, and the cost is relatively high. This can be done by: (1) The planning of the disc should be based on the heat dissipation required by the actual device; (2) Profit ...
