In low frequency isolated transformer design, safe and reliable
Inverter adopts low frequency isolation transformer design where inverter and output are totally
isolated and can attain excellent protecting effect over the lightning strike, surge, interference from input end
Inverter adopts full bridge structure and is suitable for all kinds of load
Full bridge structure is more costly but has wide application and reliability is the highest
Rectifier and IGBT are module packed
IGBT is module sealed and is capable of sustaining large current transiently and is fast in heat radiation.
It is sturdy and durable
Battery capacity can be expanded for long time discharge
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 shorten battery recharging time
Output voltage can be adjusted for 10%
Output voltage of standard unit can be adjusted 10% and custom ordered special voltage can be entertained
Can be used as frequency converter with also UPS function
UPS output can be set to be frequency converter and still maintain the UPS function
RS232 contact may be fitted with USB or SNMP card
If fitted with monitoring software, it can monitor all kinds of situation of UPS
LED and LCD dual display, giving full picture of the conditions
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
Multiple audio warning functions
When UPS is with problem, other than light Indicator and LCD display, there are different
buzzers giving different audio warning
Low distortion sine wave output
With perfect sine wave and harmonic wave distortion at 0 – 100% linear load less than 3%
Can be started with battery and auto-restart when mains resumed
It can be started with UPS internal battery when mains is off. UPS will be off automatically when
battery energy is exhausted. And when mains recover, UPS will re-start automatically
Highly stable output voltage
Within allowable input voltage range, the serial product maintain less than 1% change in output
Over heating protection
At failure of cooling fan and internal temperatures is too high, the unit will turn off automatically
