on Line Low Frequency 220V 3kVA UPS

On Line Low Frequency 220V 3KVA UPS

Brief introductions:

L series 1/1 online UPS, a fully intelligent digital UPS, highly combines the latest controller and the most advanced software. It takes the 6th generation low-exhaust and big-power IGBT and static switch as power devices. This kind of UPS is a perfect production of POCASA. It adopts the digital controlling technology, of which the core is high-speed on-line programmed microprocessor.

Key features:

A). Pure sine wave output, true on-line dual conversion design
B). Adopt 4 layers PCB, and SMD technology
C). High efficiency IGBT (insulated gate bipolar transistor) inverter technology
The 6th generation low-exhaust and big-power IGBT with excellent high speed switch feature, high voltage feature and large current feature. Drives by electric voltage, only need small control power. The 6th generation with lower saturation voltage, the inverter has high efficiency, low temperature, high reliability.
D). Touch screen display, with the simple operation and Intuitive data, optional display language and logo
E). Set the work mode on the display directly, UPS mode, ECO mode, EPS mode
F). Intelligent detecting function
This system microprocessor can continually online detect power status, the breaker status and all the working status of the circuit.
G). Excellent load feature
It is completely capable to load from 0-100% while no need to change to bypass, which makes sure the output reliable.
H). Cold start
When mains failure, can directly use the battery to start the UPS until the battery discharge to low voltage, when mains recover, can self start UPS.
I). Generator compatible
According to the real electric circumstance, UPS can be compatible to the generator, highly improve the generator input efficiency, save the energy.
J). Intelligent communication
With RS232 and RS485 standard collocation, optional SNMP and dry contact
K). Perfect protection
Input/output over/low voltage protection, input surge protection, phase sequence protection, battery over charge/discharge protection, short circuit protection, over-temperature protection and so on, as well as alarm function.
L). Selectable battery inspection module
Can test the single parameter and display on the LCD, battery failure will immediately alarm and inform the administrator.
M). High-powered dynamic feature
Adopt kinds of feedback control such as instantaneous control mode and virtual value, not only reach the high dynamic adjustment, but also reduce the output voltage distortion.
N). Optional input harmonic filter
Effectively restrain the input THD, raise UPS input power factor and reduce the input THD current.
