Bypass circuit can directly convert input electricity into output electricity through switch circuit. If inverter is closed

or fell, MCU-controlled high-speed static switch will automatically switch into bypass electricity, without interrupt

loaded power supply.

Bypass and main power can be a same group of power supply; it also can be a different AC (altering current).

Display communication unit:

Display unit is to show operational status and data of entire machine through LCD and LED, and through RS232,

RS485, dry contact signal, SNMP card, etc., realize long-distance monitor with background software.

L series 3/1 online UPS adopt large-screen LCD (320

240) and touch-screen design, graphical manipulative

interface, tabular data display. With 256 long record of incident, L series 3/1 can provide great help to your power

supply status

’

s analysis and management.

POCASA-styled UPS highly integrates digital technology, improves MTBF and reliability, its independent main control

board controls the whole system

’

s work. Meanwhile, it is controlled by a high-speed microprocessor, which ensures

the stability of equipment and the reliability of operation.

Besides the above chart, other components of UPS include: inverter transformer, input inductance, IGBT, SCR,

switches, etc.

5.2. Mains operational mode

The input AC will be transformed into DC through rectification and filtering, and then through SPWM Inverter, DC

outputs AC supply, through static inverter switch, AC reaches user. At the same time, DC can charge the battery

pack.
