Constant Wattage Autotransformer ,
ballast CWA from GATA produced using high quality silicon steels from Japan (Core loss >6). The high quality enamel copper wire, endured up to 200 °C, results in the lower operating temperature than usual one. The CWA ballast from GATA will automatically adjust it voltage and supplying the constant voltage value to the lamp. Thus, this CWA ballast will simply extend the lifetime usage of the lamp.
