Specifications

ups power supply 20kva with individual phase IGBT output inverter and input SCR silicon rectifier module.

 ups power supply 20kva 3 phase high frequency online topology double convertion tech of

IGBT inverter PFC silicon rectifier  

 

General introduction:

High efficiency,excellent performance,IGBT online ups of 3 phases input and output

( 3 PH 4 Wires Plus G(Ground line or PE)

High frequency topology ( with optional internal output gavanic isolation transformer)

 

widely applied to data center, network management center, enterprise server, industial installation etc.

Reliable,stable and uninterruptible power solution solving

Ac-blackout/outage/failure,

Ac input over-voltage, under-voltage,

Instantaneous voltage dips, voltage decrease and shock,

High voltage spike,

Voltage fluctuation

Frequency fluctuation

Surge voltage

Harmonic distorted voltage,current,

Noise and interference.

 

UPS structure: 

Ac-Dc rectifying: PFC integrated-circuit + SCR silicon rectifier module

Convert Ac from regular mains supply or reserve mains supply to Dc and feed to Dc bus for boosting;

Phase IGBT inverter: Fairchild IGBT inverter converts Dc back to pure sine wave Ac for load equipment,

Independent controller/control-board/CNTL real time controls and information collects to guarrantee

ups coodinative operation, feedback ups opration statuses information in time for administrator reference.

Controller control battery charge meanwhile to protect battery from damage and extend its service time.

 

Full digitalized DSP Ti high performance makes signal processor rapidly, and inceases output voltage quality, and more reliable.

 

2 Ac mains supply for 10-40Kva model, 1 Ac mains supply for 60-80Kva,

Regular mains supply and reserve mains supply

 

Enhanced protection class:

IP21 protection class keeps object of 12mm diameter out of ups enchrosurement, or water drops,

Optional dust-proof component, eg. dust-proof net improves ups' industrial protection class and

makes ups work normanlly on bad physical condition.

 

N+X parallel redundancy configuration and possible to share battery group;

Max: 8 units totally N max value=6,X max value=2

N for higher power needs, X for hot-redundancy

Provide feasible and cost-effective on-demand expansion choice for user.

Standard with parallel kits design, need only parallel communication data cable only.

 

ABM intelligent battery management

Charger board/CHGR modifies charge parameters in accordance with actual power condition;

Provide multi-charge method to optimize battery charge;

Decide intelligently best charge method in accodance with battery nature, battery qty/Dc voltage, battery level;

Science charge method extends battery service time, and it is possible to accelerate battery re-charge and shorten

charge time by increase charger units/more charger boards.

 

Richful communication slot options: RS232, RS485, AS400 out connect to dry contact, SNMP network management tool and expansion slot for special purpose.

 

Min 0.99 input power factor improves Ac ultilization;

93%-94% inverter efficiency and 98% on ECO mode lower down greatly ups' power consumption.

 

Feasible battery configuration: 28 cells +/-168Vdc, 30 cells +/-180Vdc, 32 cells +/-192Vdc

 

Optional device:

Power feedback module:

To resolve high BUS voltage because ups' load will create regenerated energy and feedback to grid or battery group.

It is a good option when ups is installed in special industrial load equipment,eg. high speed lift, electric motor etc.

 

Isolation transformer:

includes output isolation transformer and input isolation transformer.

Output transformer is used to complete isolate output N-line and Ground line(ups chassis), voltage between N and G not exceeding 1 volt. In order that load equipment will be free of electric interference, and avoid wrong operations.

Input isolation transformer is desgined there to filter out third harmonic from the grid  and reduce interference.

Avoids bad effection from other equipment in the same grid supply.

Users are free to decide/plan to add input or output isolation transformer : 10k,20k,30k,40k are built-in with isolation transformer, 60k,80k are external with transformer.

 

Dual charger boards:

It is very convenient to add one additional charger board to parallel with standard charger board to accelerate battery

charge.

 

Temperature sensor:

Such a temperature sensor is used to auto detect ups working temperature variation because SLA battery belongs to limited

lifespan stuff and sensitive to temperature changement. With such a temperature sensor, ups charger' temperature compensation will be activated via Lcd, ups will auto adjust charger voltage to protect and extend battery service time.

 

Dust filter:

Dust filter is used to keep object of 1mm diameter, especially metal object out of ups chassis to achieve IP51 protection class.

 

IP21 optional device:

Purpose-design for 60k, 80k as it is top-openning and vertical ventilation to keep object of 12mm diameter, or dropping water out of ups chassis.
