Pure Lead Tin (PLT) Batteries for UPS and Data Centers

Pure Lead Tin technology is an advanced lead acid technology ideally suited to high rate discharge applications where TOTAL reliability is demanded.

Uninterruptible Power Solution for Data Centers

Data centers are critical business hubs for banks, insurance companies, governments institutions and many other institutions. A totally reliable power supply is needed for their operations. UPS are typically used in parallel with diesel generators. On failure of the grid power the UPS takes on the load while the generator is started, stabilized and switched to take over the critical loads.

Thyristor Battery Charger

Thyristor based battery charger uses Thyristor switching principle for achieving the desired DC output. It basically consists of a transformer, a semi-conductor bridge rectifier, a filter circuit and a control circuit.

The AC mains voltage is transformed to a suitable level and fed to the rectifier bridge. After being smoothened by the filter circuit, it rectifies the AC input and feeds controlled DC output to the battery and load. The power output requirement is adjusted by using phase control technique which is provided by the control circuit. The feedback signals from the output to the control circuit are used for maintaining voltage regulation and current limit.

A new innovative model uses 16-bit DSP controller (optional) for switching and control of Thyristor for achieving desired DC output. The charger output voltage, output current, battery current, and battery temperature compensation are controlled by the Digital Signal Processor. The charger output parameters can be set or adjusted through keypad-display provided on the front panel with password protection. It has communication ports for local / remote monitoring of measurements and events.

Triumph - Tubular Gel VRLA Batteries for Solar Photovoltaic

Charge input from solar arrays some times is insufficient to keep the batteries fully charged. During sun-less days, batteries are discharged but not charged. These conditions result in battery operating in Partial State of Charge (PSOC), Cycling and Deep-cycling. Also, solar systems are installed in open atmosphere exposing the batteries to extreme temperatures. Other lead acid batteries fail in such conditions due to sulphation, stratification, corrosion and plate shedding. Moreover, remote solar installations make water top-up difficult and costs money.
