An UPS unit is regularly used to secure equipment like PCs, server farms, media transmission gear and whatever other hardware that could cause wounds, fatalities, genuine business interruption or information misfortune if the there was an unforeseen disturbance to the influence supply.

UPS units go in measure from units intended to secure a solitary PC without a video screen (around 200 volt-ampere rating) to substantial units controlling whole server farms or structures. The world’s biggest UPS is a 46-megawatt Battery Electric Storage System (BESS), in Fairbanks, Alaska which controls the whole city and close-by country groups amid blackouts.

The fundamental part of any UPS is to give here and now control when the principle control source fizzles. Nonetheless, most UPS units are additionally ready to amend regular utility power issues, in shifting degrees, including:

• Voltage spike or managed overvoltage
• Momentary or managed diminishment in input voltage
• Noise, for the most part from gear that is adjacent
• Instability of the principle recurrence
• Harmonic twisting

UPS units are partitioned into classes in light of which of the issues recorded they address. The three general classifications of current UPS frameworks are “standby”, “line-intelligent” or “on-line”.

The standby UPS (SPS) offers just the most essential highlights, giving surge insurance and battery reinforcement. The secured hardware is typically associated specifically to approaching utility power. At the point when the approaching voltage falls beneath or transcends a foreordained level the SPS turns on it interior DC-AC inverter hardware, which is controlled from an inward stockpiling battery.

The line-intelligent UPS is comparable in operation to a standby UPS, yet with the expansion of a multi-tap variable-voltage auto transformer. This is an exceptional sort of transformer that can include or subtract controlled loops of wire, so it can increment or lessening the attractive field and the yield voltage of the transformer. This is otherwise called a Buck-support transformer.

In an online UPS, the batteries are constantly associated with the inverter, so no power exchange switches are important. At the point when the power goes out, the rectifier basically drops out of the circuit and the batteries keep the power unfaltering and unaltered. At the point when the power is reestablished, the rectifier resumes conveying the vast majority of the heap and starts charging the batteries, however the charging current might be constrained to keep the powerful rectifier from overheating the batteries and bubbling off the electrolyte.

System Introduction:

BPE PB & H xi Series UPS is an advanced true On-line Uninterrupted Power System which produces reliable and pure sine wave power to user’s equipment, ranging from computers, sensitive medical instruments, and telecommunication systems to industrial equipment. The On-Line design enables the system to adjust & filter power fluctuations continuously & automatically under power normal condition. During power failure, it can provide immediate back up power from the batteries without any interruption. Once the power is restored the system shall again work on mains & will charge the batteries.

ByPass power design

IGBT & PWM technology:

BPE PB & HX I series UPS used latest generation of IGBT (insulated gate bipolar transistor) in the inverter part of UPS along with PWM (Pulse width modulation) to achive maximum operational efficiency.

2. Safety Instruction:

  • This manual contains important safety instructions which must be strictly followed during installation & maintenance.
  • The UPS contains voltages which are potentially hazardous. Please contact our offices or qualified personnel for any services.
  • The UPS has its own internal energy source. The output receptacles may contain electricity even when UPS is disconnected to the utility power.
  • Ground wire must be connected at the input at the time of installation.
  • UPS should be connected with single phase input 220v 3 wire phase. Neutral and earth and respective points marks LNE.
  • Batteries must be replaced or maintained by qualified personnel.
  • Replacement of batteries must be subject to quantity the types of original specifications.
  • To avoid explosion, keep fire or heating resources away from battery or battery pack.
  • Do not disassemble or damage the batteries. The electrolytic efficient is poisonous and harmful especially to eyes and skin.
  • The batteries contain high voltage and current with great risk.
  • Do not short circuit the battery terminals.

4.Installation & Operation

Unpacking & Inspection:

Examine the packing carton. Notify the carrier immediately, if damage is present. Retain the package for future use.

UPS Installation:

Connect the input power to a MCB of recommended capacity of distribution box. Charge the batteries for 8 hours before use. The UPS will recharge the batteries automatically whenever its power card is plugged into a wall outlet. You may use the UPS immediately without recharging but the backup time may be less than the rating. Connect the output load to the UPS. It is mandatory to connect ground point to avoid any malfunctioning of UPS.

Operational Instructions:

Ensure that the installation procedures and metering, controls, indications as specified, are followed and the battery of rated voltage is connected to the system.

To Start The Chargers:

Make the charger On/OFF switch ON. The Charger ON LED will Glow.

To Start The Inverter:

  • Press the reset switch to remove any spurious indication, press reset switch to reset the system. Then press start switch “INVERTER ON LED” will glow and output AC voltage can be seen on the meter. After about 10 sec, “LOAD On INVERTER LED” will glow. Check the output voltage as required on meter.
  • Connect the load at output of the system and ensure its satisfactory working.
  • The inverter may trip in following conditions.
    1. a. Overload
      b. Low battery
  • Output (AC) Over Voltage.

However, if so happens the respective LED will indicate the cause of tripping. After removal of the respective cause, inverter can be started again by pressing start switch. Press reset switch to extinguish the particular LED.

To connect the battery:

  • Stop the inverter. Then put off the charger and immediately SWITCH ON the battery isolator (back side of UPS). Now put the charger ON.
  • If the battery is discharges, the charger will start charging battery automatically. In case the battery is charged, charger will remain on in float mode.

It is always advisable to keep the charger throughout ON, for effective monitoring of the batteries. This keep the batteries in charges conditions always and provide the backup at the time of mains failure, The inverter may be switched OFF when not required, but the charger should always be kept ON.

The standby, also called off-line UPS, gives just the most essential components of an UPS. They give surge insurance and battery reinforcement. The ensured gear is regularly associated specifically to approaching utility power.

At the point when the approaching voltage falls underneath or transcends a foreordained level the Standby connects with its inside DC-AC inverter, which is controlled by an inward stockpiling battery. The UPS offers a reasonable other option to a line intuitive UPS for the assurance of PC and telecom peripherals.

A standby is the most fundamental type of Uninterruptible Power Supply framework, where the heap is provided by the approaching mains supply without adjustment or direction while the mains supply stays inside a predefined input window.

The UPS unit tracks the mains supply voltage and recurrence varieties. At the point when the approaching mains supply surpasses the predetermined amount, it switches on the inverter to keep on supplying energy to the heap. The inverter will switch on inside a couple of milliseconds, which is typically longer than that experienced with a line-intelligent UPS.

Double Battery UPS


A standby will decrease the approaching people, spikes or electrical clamor. These unsettling influences won’t be totally kept from going through to the charge and any huge voltage spikes or people that may surpass the info voltage setting will cause the UPS to change to inverter control.

Amid brief span mains supply disappointments the UPS will keep on supplying energy to the heap utilizing the inverter. In any case, steady brief term supply disappointments will prompt pointless release of the battery.
Most standby UPS units keep running for a brief span of around 5-10 minutes, along these lines the main choice to accomplish a more extended run-time, as on account of a power outage, is to get a bigger UPS.

The battery charger will be and large revive the batteries to 80% inside 8 hours to give an adequate battery level with the goal that it’s prepared for whatever it’s required.
