Notes
1 Continuous short circuit protection is provided. Long-term continuous operation in
this mode is not recommended. Converter will auto-restart once fault has been
removed
Specifications typically at 25°C, normal line, and full load, unless otherwise
stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please consult factory
for specific model information.
