QPS is the brand name for industrial power products, electronic and electrical apparatus manufactured by SETM. Our well-known range of products include power transformers like the K-factor transformer, UPS (Uninterruptible Power Supply) transformer and marine transformer. QPS transformers are widely in demand for marine industries, commercial building, laboratories, telecommunication, manufacturing, automation production processes and in the large electrical utility rooms where electronics equipment are enclosed. The transformer is used to filter out voltage spikes of current and serve as step-up or step-down the supply voltage. Other QPS electrical apparatus such as automatic voltage transformer, detuned harmonic circuit filter reactor and line reactor are suitable for industrial operating environment. With the continuous progressive development in all phases of our design process, we are capable to custom build transformers according to our customers’ specifications.
