Uninterrupted Power Supply
Uploaded on : February 2010
Product and Applications
Continuous power has to be supplied to certain essential equipments like control systems in power plant, process plants and computer installations. Wherever such continuous power supplies without failures for even a fraction of a millisecond are required one has to provide Uninterrupted Power Supplies (UPS). These systems provide power to the connected load even if the mains fail for a fraction of a second under any condition. The UPS utilizes the domestic power at 230 volts for charging the battery while the battery provides DC supply to generate 230 volts AC in case of power breakdown.
The range of power varies from 500 VA to 250 KVA. Units offering 1KVA, 5KVA, 10KVA, 50KVA, 100KVA, and 250KVA are available.
Industry Profile and Market Assessment
The UPS of large capacity for Industrial uses are manufactured by large licensed units. The smaller capacity Systems are manufactured in Small scale sector. The licensed capacity of individual unit varies from 500 to 1100 nos per annum. Due to chronic power shortage in almost every State and the growth of industry, this product has ample scope. Both the larger capacity UPS and the smaller ones needed mainly in computer sector has a good growth potential. The computer industry is a high growth industry and under the present operating systems every PC requires an uninterrupted power supply for smooth functioning of the computer. A small unit with a manufacturing capacity of 100 units per annum can easily fit in the system.
Manufacturing Process & Know How
It consists of Power supply circuit, highly stable regulated output voltage short circuit protection facility, DC power generator or battery backup, Inverter circuits, Ripple and noise suppression circuits. DC power is inverted and AC output is regulated well. Control circuits are provided to switch over to this supply immediately when there is a power failure.
This is manufactured like any other Power Supply except that the regulation and control circuits have to be doubly checked before final assembly, testing and packing. All kinds of tests like Temperature, Humidity etc. have to be conducted along with the normal tests for its different parameters.
A good quality transformer and inductance winding facility is required. Indigenous Technology is well updated. There is no restriction on foreign know how. Normal requirement is in the range of 10 to 50 KVA . However there is also demand for the smaller versions mainly from the computer users. For the purpose of calculation 10 KVA unit at a selling price of Rs. 1.5 lakhs is taken. A sale of 100 units per annum is estimated for a typical manufacturer.
Plant and Machinery
The major plant and machinery involved in the operation include Oscilloscopes, bridges, Digital multimeters, power supplies, signal generators, pulse generators, automatic testing systems, modular design system, soldering iron, Presses, punches, drilling machine, winding machine, Testing set up. The total cost of machinery is estimated to be approximately Rs 100 lakhs.
Raw material and Components
The major components involved are coils, transformers, transistors, integrated circuits, capacitors, microprocessors, cabinets, panels, DC power generators etc. The total cost of raw material and components is estimated to be approximately Rs. 60 lakhs.
Land and Building :
The project requires a built up area of 300 sq.mts. and the open land area of 900 sq.mts. The total cost of building is estimated to be approximately Rs. 10 lakhs. The cost of land will vary from place to place.
Manpower
For smooth functioning of the unit the requirement of man power is expected to be as follows:
| Supervisors | 2 nos |
| Office staff | 3 nos |
| Skilled workers | 5 nos |
| Unskilled workers | 10 nos |
| Salesmen/Technicians | 3 nos. |
The total salary bill annually will be Rs. 7.20 lakhs.
