SVTEL is one of the leading manufacturer of Telecom Power Conversion Devices, including standard and customised  AC/DC power supplies as well as DC/DC converters. SVTEL manages customer needs and monitors the latest trends  regarding power for a multitude of applications  in the areas of Telecom,  Industrial Machines, Appliances, Medical  Equipment, Broadcast Systems, Military Devices, Laboratory Appliances, Test and Laboratory Equipment, Automotive  Industry, Aviation Systems, Maritime Equipment......and many more.

The SVTEL FCBC ST series makes wide variety of Battery Chargers, most of which are Float cum Boost Chargers. Since  most of our Float Chargers are being used  for  the EPABX, RAX, MAX, Telecom CPE, Telecom Fiber Mux and other Digital Electronic Telephone Exchanges & other communication equipment, almost all the models are designed for telecom  applications.  In addition to wide variety of 48 Volts Chargers used  in the Telecom sector, we also manufacture Custom- Designed Battery Chargers of 12, 24, 36, 60, 110 & 220 Volts (nominal) outputs in 3, 6, 10, 12, 16, 20, 25, 30, 40, 50,  70, 100, 150 & 200 Amps capacities.

Float Chargers having current limits for total output current and separate limits for battery charging current and load  current are manufactured. In some Float Chargers special care is taken to keep the maximum voltage at load terminals  below specified limits (whenever specified), since the required voltage for charging the batteries is higher and is as per  recommendation  of  battery manufacturers.  There  are  number  of monitoring  points  provided  and  annunciation, audible alarm and choice of 1,2 or 3 meters for indicating output voltage, total output current, load current, battery  charging and discharging current  (by center  zero meter) etc.

Models with analog meters  in place of Digital ones are also available. Single phase  input mains supply  is preferred upto  3 KW output, with a possibility of wide voltage variations. For all higher power output chargers, three Phase input  supply  is preferred. Reliability  is enhanced  through  the use of glass epoxy PCBs with  solder masking and  legend printing  in addition to roller tinning / solder coating and gold / nickel plating for tabs, which are in contact with the edge connectors.  A  detailed Operating  Instruction Manual  and  Service Manual  incorporating  information  on  charger ensures ease of use & maintenance. Low down-  times and ease of  service-in a  few minutes,  is ensured by designing easy  to access, modular  layouts, clear component  identification and plug  in  type  round  shell connectors.
