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.
