Frequency inverter maintenance Cautions

1) UPS should be noted that the use of a well-ventilated environment, conducive to heat and keep the environment clean.
2) Do with  6000 watt power inverters  loads, such as cash registers, fluorescent lights, air conditioning, etc., to avoid damage.
3) UPS output load control in about 60% for the best, highest reliability.
4) UPS load is too light (eg 1000VA, 100VA UPS with load) may cause deep discharge of the battery will reduce the battery life, should be avoided.
5) appropriate discharge, helps cell activation, such as long-term non-stop electricity, every  2500 watt power inverter  months to be artificially broken mains load discharge time with UPS tape, so you can extend the battery life.
6) For most small UPS, go to work and then open the UPS, to avoid load at boot time to start, should work to close UPS; For network room UPS, because the majority of the network is 24 hours, so the UPS must run around the clock.
7) UPS should be charged after discharge to prevent battery damage due to excessive self-discharge.

How to choose a good inverter power devices

Select essential elements of the inverter main power is currently using more power components Darlington power transistor (GTR), power FET (4000 watt power inverter), insulated gate transistor (IGBT) and a turn-off thyristor (GTO) and the like. Used in small volume, low pressure systems more devices to MOSFET, because the MOSFET has a low on-state voltage drop and higher switching frequencies; capacity in the high-pressure system in general IGBT modules are used, this is because as the voltage MOSFET 5000 watt inverter its on-state resistance also increased, while the IGBT has a large advantage in the capacity of the system; while large capacity (100KVA and above) systems, in general, are used GTO as power components.

Introduces the working principle of the inverter

Transformer is a kind of DC to AC transformer, it in fact and converter is a process of voltage 6000 watt power inverters. The converter is the transformation of the city power grid AC voltage is 12V DC 4000 watt power inverter, and the 12V output DC voltage Adapter into high-voltage alternating current frequency; two parts are also using a pulse width modulation more with the current (PWM) technique
