12 volt power inverters Kind of emergency power characteristics

1.EPS emergency power; kind of chargers, inverters, batteries, isolation transformers, switch devices such as the composition of the inverse of the DC power to AC power for emergency 3000w charge inverter power supply. Applicable to interrupt the power supply to allow more time is 0.25s load. 
2.UPS uninterruptible power supply; its main power converter with energy storage devices (batteries) and switch (electronic and mechanical) still constitute a guarantee of AC UPS power supply continuity. Apply to allow uninterrupted power supply at the millisecond level load. 
(3) self-emergency diesel generators; it is diesel powered, drag consisting frequency AC synchronous generator power generation equipment. Rapid self-starting generators for uninterrupted power supply to allow more time for the 15s building. Emergency power production working hours shall be considered technically 12V inverter charger allowed outage time, when the generators start automatically with the use, not less than l0min. 
4 automatic investment independent of the normal power supply dedicated feeder line device. Applicable to the device operating time since the vote to allow uninterrupted power supply to meet the time 1.5s or 0.6s more emergency power. Where allowed outage time in milliseconds, and the load capacity is not particularly important, if possible using DC power, the battery pack should be used as an emergency power source. 
5 self-emergency gas turbine generator sets; It is AC power inverters based gas turbine-driven, drag frequency AC synchronous generator consists of power generation equipment.

12 volt inverter Emergency power supply works

EPS emergency power supply on the broad sense refers to the normal power supply is interrupted, you can load a user to key independent short supply emergency power 220v power inverter unit (EPS: Emergency Power Supply), including of course the title of this generalized emergency diesel generators. With static power inverter in building fire emergency should be as gradual application of power, the current domestic supply and fire protection industry has been referred to as the EPS is designed primarily refers to the use of power electronics inverter stationary emergency power system (hereinafter referred to as the unified EPS). 
EPS emergency power supply system includes rectifier chargers, batteries, inverters, each switch device and a part of the system controller. Which is the core of the inverter, usually single CPU or DSP part of the inverter SPWM modulation control, and thus obtain a good AC waveform output; role rectified mains charger when the input is normal for the battery pack to achieve timely Charge; role inverter is abnormal when the mains, the battery pack is stored DC power into AC output, stable and sustainable supply of electricity load equipment; each switch device to ensure that 3000w charge inverter the load on mains power and inverter output between smooth handover; system controller for real-time control of the entire system, and can be a fault alarm signal and the received signal remote control linkage, and through standard communication interface from the host computer system for remote monitoring EPS.

12 volt inverter Emergency Power Overview

Emergency Power Emergency figure present cars, trucks need to provide when the engine is started by a 12-volt car battery that comes when the car battery is not available, 48v to 220v power inverter the car will not start, then you can use the car's own emergency power supply instead of the battery , start the car. 
Now with an emergency power supply can also be a lot of other rich features, emergency power becomes a broader sense, for example, can charge for mobile phones and other electrical appliances can be used as lighting, can provide power to the laptop; with a pump can also give tires cheer; inverter with 220 volts can also output to other electrical supply. 
When selecting products should be noted, first of all to the good emergency power supply for easy maintenance, even no maintenance, long battery life, can adapt to 12V inverter charger harsh working conditions, for example, some products can work in a wide range of temperature.
