PUNE: As India launched the earth observation satellite RISAT-2B on Wednesday, the employees of VCB Electronics, situated in a small village in Khed Shivapur, were filled with pride for their small contribution to this big venture.
VCB Electronics provided Indian Space Research Organization (Isro) with the Hybrid Micro Circuit (HMC) DC-DC converters of 5V output, which were used to power small modules in the launch vehicle and satellite.
The company director (commercial) Sandip Chavan said the HMC DC-DC converters were earlier imported from the US or used in the larger printed circuit board versions which were heavier and used up more space. The indigenous converters are fitted with an inbuilt electro magnetic interference filter, a feature absent in the imported components.
"The challenge was to make it as small and light as possible and also resistant to adverse conditions of space. Our product weighs less than 60g. It can work at a temperature range of 125°C to -40°C and give an output of 5V for small modules.," B S Bhosale, Technical Director of the company said.
A team of 12 engineers and 18 process staff were involved in its designing and production along with some IISU scientists.
"We have provided the Isro with 40 such HMC DC-DC converters out of which seven have been reportedly used in the RISAT 2B," B S Bhosale, technical director of the company said.
Chavan said,"The HMC DC-DC converter will cost around Rs6 to 8 lakh if imported from the US but our product costs Rs1.5 lakh to 2 lakh."
