Apart
from manufacturing the mentioned test sets, we also
manufacture equipment according to
specific requirements of
customer.
 BRAZING TRANSFORMER
BATTERY
CHARGER
HIGH VOLTAGE GENERATOR FOR ELECTROSTATIC APPLICATION
ISOLATION & ULTRA ISOLATION TRANSFORMER
SPECIAL TYPE OF TRANSFORMERS & INDUCTORS
X-RAY TRANSFORMERS
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.

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.
