On-Line UPS (low frequency) – NS
Product Introduction

 

Specially for precision instrument and high end computer

100% made in Taiwan, the On Line UPS system is suitable for load of SMT, OA quipment, automatic testing system, computer and related products. In IGBT/PWM advance and module design, the equipment is highly reliable, excellent quality and exceptional long MTBF.

 

Feature:
       

In low frequency isolated transformer design, safe and reliable

LED and LCD dual display, giving full picture of the conditions

 

Inverter adopts low frequency isolation transformer design where inverter and output are totally isolated and can attain excellent protecting effect over the lighting strike, surge, interference from input end

 

LED can display system status, battery level and failure indicating. LCD can display input voltage, output voltage, frequency, battery voltage, output load level, output battery level, internal temperature that give you full information of UPS status
       

Inverter adopts full bridge structure and is suitable for all kinds of load

Multiple audio warning functions

 

Full bridge structure is more costly but has wide application and reliability is the highest, too

 

When UPS is with problem, other than light Indicator and LCD display, there are different buzzers giving different
audio warning
       

Rectifier and IGBT are module packed

Low distortion sine wave output

 

IGBT is module sealed and is capable of sustaining large current transiently and is fast in heat radiation. It is sturdy and durable

 

With perfect sine wave and harmonic wave distortion at 0 – 100% linear load less than 3%
       

Battery capacity can be expanded for long time discharge

Can be started with battery and auto-restart when mains resumed

 

In additional standard unit equipped battery, the product can be connected to large capacity battery for long time discharge and can fit with large current charging board to short battery recharging time

 

When UPS off and power is supplied by internal battery, UPS will be off automatically when battery energy is exhausted. And when mains is resumed, UPS will re-start automatically
       

Output voltage can be adjusted for 10%

Highly stable output voltage

 

Output voltage of standard unit can be adjusted 10% and custom ordered special voltage can be entertained

 

Within allowable input voltage range, the serial product maintain less than 1% change in output
       

Can be used as frequency converter with also UPS function

Over heating protection

  UPS output can be set to be frequency converter and still maintain the UPS function   At failure of cooling fan and internal temperatures is too high, the unit will turn off automatically
       

RS232 contact may be fitted with USB or SNMP card

   
  If fitted with monitoring software, it can monitor all kinds of situation of UPS
