Modular DC Supplies

The Series-60 aluminum-framing system challenges steel in heavy-duty machine supports, frame-building, linear-motion, and material-handling applications.


Modular dc power supplies in the Phaseo family incorporate features such as integrated overload, short-circuit, overvoltage, and undervoltage protection. The supplies are regulated and switch mode with adjustable outputs and include three different lines: single-phase and three-phase power supplies and an ultracompact version.

Other features include a high degree of output voltage stability, and a modular format allowing installation into control panels. The single-phase power supplies work from 100 to 240 Vac and produce 12 or 24 Vdc. The three-phase ABL7UPS is available in 10, 20 and 40-A versions. All three models are designed to accept 420 to 520 Vac and output 24 Vdc. The ABL7CEM is the most compact member of the family and accepts 100 to 240 Vac and outputs 24 Vdc. All supplies deliver a voltage accurate within 3%, regardless of load and supply voltage, within a supply voltage range of 85 to 264 Vac. An output voltage adjustment potentiometer allows compensation for line-voltage drops in installations with long cable runs.
