Profile: Foster Transformer Company specializes in the manufacturing of transformers. Our products includes class 2/control transformers, LED power supply, ferroresonant transformers, current transformers, power transformers, autoformers, isolation transformers, EMI filters and inductors. Our class 2 transformers are low voltage (< 30 VRMS for dry locations), low power (< 100 VA) devices that are used in common residential, commercial and industrial control applications including HVAC controls, vending machines, appliances, low voltage lighting, alarm & intercom systems. Because of their low output voltage and limited power capability, class 2 circuits are often given special consideration in terms of circuit spacing and wiring requirements. Our industrial control transformer usually powers circuits similar to those of a class 2 control transformer, but at higher power levels. Often operating at 12 V or 24 V, low voltage industrial control transformers enhance safety by isolating the control circuit from the incoming line and reducing the voltage to safer levels; however, since their output is not considered to be power limited, additional limitations apply to circuit spacing, wiring & overload protection.
