Power supplies for industrial applications

The latest generation of compact, DIN rail mountable power supplies ranges from 2.1 A single-phase to 40 A three-phase and can handle an input voltage range of 100-240 VAC for single-phase devices to 400-500 VAC for three-phase devices. The power supplies are designed to withstand tough industrial environments for optimal reliability and functionality. They feature a buffer module—a power back-up device that supplies standby voltage during brown-outs or load peaks for a defined period of time. The power supplies tolerate ambient temperatures ranging from -25 to +70°C and feature short-circuit, overload, and continuous open-circuit protection. They have extensive worldwide agency approvals, such as UL 508, CSA, IEC, and EN, to meet the requirements of OEMs with universal applications.
