Bringing the Power: Power Supplies Episode 7

In ROK Talk on Industrial Components Episode 7, Bill and Paul talk to Industrial Control Lead, Derrick Hinds, about the most important factors in choosing a power supply and the typical mistakes that are made when selecting a power supply.

Control Circuit Transformers

Our Global Control Circuit Transformers are designed to reduce supply voltages to control circuits, providing greater safety to operators. IP2X finger-safe terminal covers and fuse covers are provided on all units for added workplace safety. Our transformers isolate the control circuits from power and lighting circuits. They accommodate the momentary current inrush caused when electromagnetic components are energized, without sacrificing secondary voltage stability per NEMA ICS2-100.
