Lithium High Frequency Online Tower UPS
Online UPS Summary
An Online UPS output is independent of voltage and frequency variations of the mains.
-
Offers the highest level of critical load protection as the load is supplied with closely regulated power at all times
-
Has a load break of less than 0ms when transferring between inverter and bypass
-
-
Is totally transparent to the load in the case of a mains failure
-
Is the most expensive capital cost of UPS systems
-
Has a higher running cost than other types of system, as the rectifier and inverter are permanently on load.
Features:
1.
The overall efficiency is as high as 98%; Provide ECO mode, achieving efficiency of over 99% and reducing power loss of UPS. 2. Design to meet the requirements of the power grid and provide a wide input voltage range of 210VAC~475VAC. Suitable for harsh power grid environments. The excellent input frequency range enables UPS to adapt to different power supply devices such as generators.

More details:
The SMPS based CONVERTER should be based on High Frequency (20 KHz and above)
Switch Mode techniques.
Resettable Fuses shall be provided, wherever appropriate, to protect the module against failure
of control / sensing circuit.
The design shall have suitable time delay / hysteresis to avoid hunting during switching ON and
OFF of the system. The module shall disconnect at 150V and reconnect at 170V AC.
Switching ON and OFF the fan shall be temperature controlled. In case of fan failure the module
shall have automatic protection to switch off the module above 70 deg centigrade and restore
automatically with reduction in temperature. It shall not cause any fire hazard. The fan shall also
be protected against short circuit by providing a fuse.
The CONVERTER modules shall have forced cooling and only DC fan shall be used.
DC Output Characteristics
The module shall be capable of operating in "Auto Float cum-Boost charger" mode. It shall be
programmed to operate as a float rectifier or a Boost charger depending on the condition of the
battery
Auto Float Mode
Float voltage of each rectifier module shall be set as given below:
Normal Float & Boost voltage for VRLA battery is 2.25V and 2.3V/Cell respectively.
For conventional battery it shall be 2.15V and 2.42V/cell, respectively.
For 110V/20Amp charger 55cells of 2V each will be used and for 48V/25A charger 24 cells of 2V
each will be used.
The module should have a range from 2.0 - 2.3V/cell in float mode & 2.2 - 2.5V/cell in boost
mode to meet the requirement of VRLA as well as conventional batteries.
The DC output voltage shall be maintained within ± 1% of the half load pre-set voltage in the
range 25% load to full load when measured at the output terminals over the full specified input
range.
Auto Boost Charge Mode
In auto boost charge mode, CONVERTER shall supply battery and equipment current till
terminal voltage reaches 2.3V (VRLA battery) /2.42V (Low Maintenance battery) per cell.and
shall change over to Auto Float mode after a defined delay of 0, 1, 2, 4 hours adjustable, to be
set as per battery manufacturer's specification.
Efficiency
The efficiency and Power factor of the CONVERTER in auto float and auto boost mode shall be
as follows:
Nominal input - 150-275V
Output - Full Load, Efficiency > 90% and Power factor >0.95 to unity
And for
Nominal input - 150-275V
Output - 25% to 100%, Efficiency > 85% and Power factor >0.9
Note: Active power factor correction circuit shall be adopted.
Total Harmonic Distortion
The total line harmonic voltage distortion shall not be more than 10%.
The total current harmonic distortion contributed by CONVERTER at the input shall not exceed
10% for all input condition and load 50% to 100% of the rated capacity.
Soft Start Feature
Slow start circuitry shall be employed such that CONVERTER module output voltage shall reach
its nominal value slowly within 10 to 20 seconds, eliminating all starting surges.
The maximum instantaneous current during start up shall not exceed the peak value of the
rectifier-input current at full load at the lowest input voltage specified.
Voltage Overshoot/Undershoot (with battery disconnected)
The CONVERTER modules shall be designed to minimize output voltage overshoot /
undershoot such that when they are switched ON, the DC output voltage shall be limited to ± 5%
of the set voltage and return to its steady state within 20 millisecond for any load of 25% to
100%.
The DC output voltage overshoot for a step change in AC mains from 150V to 275V shall not
cause shut down of CONVERTER module and the voltage overshoot shall be limited to ±5% of
its set voltage and return to steady state within 20ms.
The modules shall be designed such that a step load change of 25% to 100% or vice- versa
shall not result in DC output voltage overshoot/undershoot of not more than ±5% of the set value
and return to steady state value within 10 millisecond without resulting the unit to trip.
Alarms & Indication of CONVERTER
The following indications, controls & measuring points shall be provided on the front panel of
CONVERTER
a) CONVERTER on Auto Float mode FLOAT Green
b) CONVERTER on Boost Charge mode BOOST Green
c) Mains available MAINS Amber
Alarm Indication with LED:
a) Rectifier module over voltage OVER VOLTAGE Red

Note: "Provision shall be made for stopping the audio alarm with a non-locking push button.
a) Float voltage adjustment (float)
b) Boost voltage adjustment (boost)
c) Overload current setting (OL)
d) Voltage monitoring point suitable for measurement by standard multimeter.

FAQ
Q1: What's the difference between tower and rack-mounted UPS?
Tower UPS is vertical, ideal for offices and homes; rack-mounted is horizontal, suited for server rooms.
Q2: Do you provide customized product?
We provide OEM and ODM services for clients.
Q3: What's the difference between online and offline UPS?
Online UPS continuously provides stable, high-quality power (stable voltage, stable frequency) by converting mains electricity through its rectifier and inverter, ensuring uninterrupted power without delay during outages, making it ideal for critical systems that require consistent power. In contrast, an offline UPS supplies power directly from the mains and only switches to battery backup when the mains fail. This switch introduces a brief delay, and the power quality depends on the mains supply, making it more suitable for less critical applications like office equipment.
Q4: How long does the lithium battery last?
The lithium battery lasts 5-10 years, depending on use and maintenance.
Q5:How do you package it ?
A:We pack in cartons.
Q6:what's the MOQ?
A:For LOGO, color or other special requirements, a minimum of 20 is required. If you do not have these requirements you can buy
directly, we will ship within 3-10 days.
Q7:Can you produce according to the samples?
A:Yes, we can produce by your samples or technical drawings. We can build the molds and fixtures.
Q8:Do you test all your goods before delivery?
A:Yes, we have 100% test before delivery.
Q9:What is your terms of delivery?
A:EXW, FOB, CFR, CIF, DDU.
Q10:What is your terms of payment?
A:We accept all methods of payment: paypal, T/T, credit card, West Union... Please contact us for more details.
