Technical
Details
Transformer
: Double wound buck & boost type continuously rated, impregnated in insulating varnish is used for output voltage control. The transformer is made of
(CRGO) silicon Steel Lamination & Electrolytic copper wire is used for
winding Voltage
Control
: A motorized sleeplessly controlled auto transformer is used for controlling the output
voltage.
Electronic Circuit: Control Circuit with I.C. is provided to continuously monitor the output
voltage.
Input Voltage Ranges:
Single
Phase : 130-285 any range in between
Three Phase
: 225-440, 300-44-, 340-440 or as per requirement
Output
voltage : 220-240 V + 1% or 0.5 % (Single Phase)380-415 V + 1% or 0.5 % (Three
Phase)
Control :
-
Potentiometer for output voltage setting.
-
Switch for manual and auto use.
-
Push button to increase or decrease voltage manually in case of manual position.
Metering : A Voltmeter is provided to indicate the output
voltage.
Protection :
The design of the unit is such that it can withstand 20 percent overloading for short durations without any damage. Each unit consists of minimum-maximum range indicator, motor movement control micro switch at the end of the range and oil imlet & outlet valve, oil level
indicators, lifting arrangement, for whole unit and transformer only, cooling radiator as per the capacity
requirement.
Optional :
Amper meters, on-off switch's fuse, change over switch, under-over voltage protection & indication, with or without
tripping, arrangement, single phase protection, with or without contactor.
