UPS (OFF-Line) US3-48V

Uninterruptible power supplies (UPS) US3 for connecting consumers, critical to the AC voltage 220 disappearance of 50 Hz or 380 V 50 Hz 3 phase. This can be:
1) electrical equipment of a private house and office: gas boiler, pumps, refrigerators, lighting, audio-visual equipment, computer and office equipment, alarm system and video surveillance, automatic gates, etc; <. br /> 2) neenergoomkoe industrial equipment.
in the presence of the mains voltage US3 transmits it to the load, and during loss US3 voltage begins to generate its own. It converts the voltage of 48 V DC (4 series-connected 12-volt battery) into stable AC 220 V 50 Hz. In this form of the output voltage is a pure sine wave. US3 provides power to all kinds of power consumers with total capacity of up to 3 kVA.
Unlike petrol, gas or diesel generator during loss of mains voltage US3 almost instantaneously begins to produce power from the battery. Connected devices voltage failure even not notice because switching time is from 0.002 to 0.006 seconds. Also, the device, unlike the generators during operation does not create noise. When not very long power failure US3 device with battery set could successfully replace a generator during long disappearances to provide a large runtime it can work with any type of generators. . In this case the autonomy of the system is almost unlimited
Features:
§ high power - 3 KW;
§ high overload capacity - 9 KW allows easily connect inductive load (powerful motors, pumps , refrigerators, electric) and capacitive loads (high-power switching power supply unit, in m. hr. plasma televisions, computers). May also be connected powerful incandescent, fluorescent (economical) lamps, washing machines, etc .;
§ high efficiency during battery operation - up to 90%;
§ sinusoidal voltage in battery ;
§ ability to connect many different types of gasoline, gas and diesel generators as a remote control, and manual;
§ have the ability to automatically start the generator of periodic training;
§ battery test at inclusion;
§ high battery charging current - 35 A;
§ have temperature compensation battery charge voltage;
§ algorithm implemented by three-stage charge batteries;
§ withstand a short circuit (SC) output;
§ possibility of several US3 (. 3 pieces) in parallel, allowing proportionally increase the power (kVA to 9);
§ possibility of operation in a three-phase 380 V 50 Hz (3 necessary device total capacity - 9 kVA); < br /> § in three-phase mode for each phase allows parallel operation of multiple inverters (up to 3 pcs.), with total capacity of 27 kVA is obtained;
§ to organize a parallel, three-phase and three-phase-parallel operation does not need any additional devices, only simple cable;
§ for remote monitoring and control used by RS-485, USB;
§ has a control program on a personal computer (PC) running under Windows;
§ keeps records time UPS, power generated by them and the number of network interruptions;
§ two variants of fastening: 19 "rack on the wall.

The UPS has the following protections:

* overcurrent at output;
* against short circuit on the output;
* from the low and high temperature environment (operating range - from 0 to 45 degrees);
* overheating of power cells and transformers in the device;
* from incorrect connection of batteries;
* from the high voltage battery;
* from low voltage batteries
