Solar thermal energy controller series

20 Sep 2012

Steca’s latest solar thermal energy controller series has been certified for the North American market. Adding to the current product range is the new series: Steca TR A501 T U, TR A502 TT U, and TR A503 TTR U. After testing by the state-approved inspection authority, the National Recognized Testing Laboratory (NRTL), these controllers have now received the CSA label for the US and Canada. The Steca TR A503 TTR U provides high power, convenient installation and operation, two triac outputs, one relay output, and numerous additional functions. The new solar thermal controller has five inputs, two RPM-controllable triac outputs that can also be used as 0-10 V outputs for controlling high-efficiency pumps, and an additional relay output for individual programmability. The compact designer housing, typical of the new controller series, can be easily integrated into solar stations and used for wall and top-hat rail mounting.
