MVAB120 : Murata Power Solutions Launches Highly Efficient Compact 1U Open Frame 120 W AC/DC Power Supply

Murata Power Solutions today announced the MVAB120 series of high efficiency, typically up to 91%, open frame single output 120 Watt power supplies aimed at a broad range of telecom and industrial applications. Measuring just 101.6 x 50.8 x 34.3 mm (2 x 4 x 1.35 inches), the low profile units satisfy the 1U height constraints of this industry standard footprint.

The high efficiency design of the MVAB120 ensures that waste heat is kept to a minimum and the units are capable of delivering up to 75 W using convection cooling only. Just 250 LFM forced airflow is required for the supply to operate at the 120 W full load output.

The series comprises three single output models covering the nominal outputs of 12, 24 or 48 VDC. Accommodating the full universal range of input voltages, from 90  - 264 VAC and 120 – 300 VDC, the MVAB120 also meets the EU PFC directive for active power factor correction. Safety approvals include the internationally recognized UL/EN/IEC 60950-1:2005 2nd edition standard for IT and commercial equipment. The units also comply with IEC/EN 61000 Class A and EN55022 Class B standards for emissions and immunity.

Suiting most operating environments, the MVAB120 series can deliver full load from -10 to + 50 degrees C, and is capable of start-up from temperatures as low as -20 degrees C.

Output protection features include overcurrent, overvoltage and overtemperature.

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…
