[1]   Click to Enlarge Battery Charger This charger is suitable to deliver high current at low voltage to the discharged battery (rechargeable), which after getting charge for some time start decreasing the current with a consistent rise in the output voltage. This mode of charging is taper charging. Input Voltage: 415V, 3 phase, 4 wire, 50Hz, AC. Outputs: The DC current & voltage output varies between maximum and minimum value. High current i.e. maximum value of current is required for initial charging of the discharged battery at minimum voltage. Gradually, this current decreases to a minimum value at maximum voltage. Series: BC X1X1X1 A; X1X1X1 denotes maximum current value. Type: YYYVXXXAZZZV; YYY denotes maximum voltage value. XXX denotes minimum current value. ZZZ denotes minimum voltage value. The transformer will be air-cooled, delta-star connected with ?OFF-Load? tap changing facility. The transformer is connected to full wave silicon rectifier. Metering: One Ammeter and One Voltmeter provided to indicate the charging current and voltage would be provided. Protection: Triple pole switch, H.R.C. fuse, knife switch & rewireable fuse of suitable will be provided on AC & DC sides respectively. A thermal Relay will be incorporated with the contactor for protection of diodes against overload due to short circuit. The rectifier assembly will be suitably provided with a surge suppression network. Provision for terminals of output connections incorporated. See Enlarge Click to Enlarge Brazing Transformer Brazing Transformers manufactured are Indoor types, double wound step down, oil immersed, mounted on an MS tank fitted with Conservator tank, Silica gel breather, inlet & outlet drain valve, thermometer pocket with 4" dial type thermometer, Lifting lugs, 2 earthing studs, Oil level indicator, output bars etc. Counter weight arrangement with adequate fittings is provided in a simple way to bear the weight of the cables and tong. Current range selector switch, analog ammeter, contactor for Foot switch operation etc. are fitted within the control unit fitted to the tank. Padlock with duplicate keys for tap changing switch & Foot Switch for ‘Local’ as well as ‘Remote’ operation is also provided. Input Voltage: 400 Volts, 3 phase, 4 wire, 50 Hz, AC. Or 230V, single phase, 50Hz. AC. Capacity: 20KVA Max. Secondary Current: 4000 A Max. in steps like, 5 Volts - 4000 Amps.,10 Volts - 2000 Amps. by Series Parallel Link connection. Secondary Voltage: 5 to 10 Volts, 50 C/S. All the voltage specified are no load voltages and no load voltage output will not be less than those mentioned above. The transformer will conform to ISS: 2026 as far as temperature rise is concerned. However, sets as required by customer are also manufactured. See Enlarge [1] Go to Top
