(a 250va transformer with two 24v secondary windings = stp-0250-2024. a 1200 va transformer with two 120v windings = stp-1200-2120.) where dissimilar or multiple output configurations are required, please contact customer service for additional information. in all cases, a serialized part number will be assigned to the final product label. 2. the dimension profiles depicted for each va range are for standard transformers with 2 x 115v output configurations. dimensions of transformers with multiple outputs, dissimilar outputs or elv outputs may vary.
