MEE1 : Isolated 1 W DC-DC converter offers tight load regulation and improved efficiency

Murata Power Solutions today announced the MEE1 series, a 1 Watt single output PCB mounted DC-DC converter designed for a broad range of industrial, automation and instrumentation applications that require an isolated low-power distributed supply. These highly efficient converters, up to 86% efficient, are available in a variety of models accommodating the popular nominal input voltages of 3.3, 5, 12, 15, or 24 VDC and with output voltages of 3.3, 5, 9, 12 or 15 VDC.

Compared to similar sized and power rated products currently available on the market, the MEE1 efficiency has been increased by up to 8% and has a typical efficiency range of 76 - 86% depending on output voltage. Load regulation has also been significantly improved and is now as low as 3% across the load rate of 10 to 100% for the 24 VDC input/15 VDC output model, MEE1S2415SC. Isolation is 1 kVDC.

The MEE1 converter series is available in the industry standard SIP 4-pin and DIP 8-pin pinout formats, giving designers a choice of package depending on the space available within their end product. The MEE1 is an ideal pin-compatible drop-in replacement for updating older designs without the need for any PCB changes.

The MEE1’s isolation allows the converter to be configured to provide an isolated negative rail in systems where only a positive rail exists.

Safety certification to the internationally recognized specification UL60950 is currently pending.

The series can operate at full output power across a wide range of temperatures from -40 to +85 degrees C making it suitable for use in most operating environments.

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 E

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 p


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.
