Notes:
1.
STP transformers having dual secondary windings may be ordered by specifying
the power range, output voltage and current requirements. (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.
