10.2 Heater
Bray offers an optional heater as a field or factory installable option for the
Series 70 actuator to prevent condensation from forming inside the actuator. This
PTC (Positive Temperature Coefficient) style heater has a unique temperature
- resistance characteristic. The heater self-regulates by increasing its electrical
resistance relative to its temperature. The heater does not require external
thermostats or switches to control its heat output.
