Our History of Power Product

Tape winder from 1965

In the 1960s, our flagship products were power supplies for communication applications, and these demonstrated robust growth primarily centered on permanent power supply systems, wind-up generators and power supply systems for signal position meters. Demand also increased rapidly as a result of sales of rotating devices such as servo motors and resolvers beginning to take […]
