Ferro Resonant Voltage Regulator
At Apple Systems, we have consistently believed that Research and development always pays off. All our products are developed by us, backed by our own research and development department. The efforts has paid off, we met the Indian Railway Specifications(IRS) for Ferro-Resonant type voltage regulators, for use with Railway Signaling applications, which are by far the toughest standards for such product, set by any agency and became the second company in the country to get approval from Research Designs and Standard Organisations (RDSO) under Ministry of Railways for use of our Ferro-resonant voltage regulators for critical Railway signaling applications.

We now manufacture and supply these regulators from 1.0 KVA to 5.0 KVA.
