CONSTANT VOLTAGE TRANSFORMERS
Applications of constant voltage transformers are endless especially in extra low voltage lighting installations, where the light output and lamp life can be severely affected by a number of factors such as common voltage fluctuations on mains supply, power surges due to lamp inrush current and supply transients. These unwanted fluctuations cause frequent lamp switching and poor re-lamping schedules which can be very costly over time. With all these in mind one must also consider the costs of maintenance, blown fusses, downtime and customer annoyance caused by the need for early lamp replacement especially in multi-lamp applications.
