Cosmo Electrical Instruments

Laxmi Nagar, Delhi

We are manufacturer and supplier of Constant Voltage Transformer (CVT) that are highly reliable and have maximum efficiency. Our offered range of Voltage Transformers are widely used by our esteemed clients for its quality features.s

Engaged as a manufacturer & supplier we are providing our customers with Variable Auto Transformer. Manufactured using single layer winding on a core that is made up of high-grade cold rolled grain oriented steel, these products are developed with perfection. Rugged in construction, these products are provided to our customers in different specifications to suit their demands. Some of the salients features of "COSMO" Autotransformers are. Continuously Varable output voltage Silver plated track of carbon brush High grade carbon brush Easy replacement of carbon brush Extremely low magnetising current (about 25 of rated load) Mechanically rugged design Almost no maintenance required Capacities upto 40 amps in air cooled version conforming to IS:5142-1969

Staco Variable Transformers include a full range of single an three phase models. Standard models include input voltages from 120VAC to 480VAC. Frequencies to 2000 Hz can be accommodated. Special units for voltages to 1000 VAC are available. Below are links to detail specifications for standard units. They are categorized by input voltage, output voltage and number of phases. If you do not find the transformer that meets your application requirements, please contact ISE with your detailed specifications.
