Ultra Compact Low Power AC/DC Modules

RECOM low power AC/DC modules, RAC01-RAC02-RAC03, bring the AC into your boards with full protection and safety, reducing the number of external devices.

Home automation, telecommunications, consumer appliances, industrial controls, measurement equipment, etc;  No matter what electronics market you work in, the RECOM low power AC/DC modules will allow you to integrate the power supply into your equipment without having to use any external device, such as desktop or wall-plug power supplies.

With its ultra compact packages, the RAC-series, will provide the necessary protection and safety from the AC lines, and at the same time deliver clean and reliable DC voltage to power your board components.

RAC01 and RAC02:

The 1W and 2W converters cover an input voltage of 90-277VAC. They are available with 3.3, 5, 9, 12, 15 or 24VDC outputs. Exceptional is the extremely low no-load power rating of only 30mW at 115VAC. These AC/DC-Converters can operate over a temperature range of -25°C to +85°C and offer efficiency up to 75%. Input voltages are regulated with 2%, load variations with 6%. The RAC01- and RAC02-Models measure only 33.7x22.2x17.0mm. The MTBF
(+25°C) to MIL-HDBK 217F is specified at >1.000.000 hours.


The 3W converter shows 80mW no-load power consumption and is therefore better by a factor 6 than required by the EuP-Directive. With an input range from 90-265VAC, the outputs are also 3.3, 5, 9, 12, 15 or 24VDC. With efficiency close to 78% the units can also be used up to +80°C. The line regulation is 3%, the load regulation 6%. The MTBF (+25°C) to MIL-HDBK 217F exceeds 500.000 hours. The RAC03-Converter is slightly larger than the RAC01/03, measuring 37.8 x 23.9 x 15.6mm.


The higher rated 6W unit also features high efficiency at 80% and is available with single-and dual- outputs. The single output voltages are identical to the smaller units, the dual outputs are specified at ±5, ±12 and ±15VDC. The inputs are also 90-264VAC. The no-load power at <250mW at 115VAC is also considerably below the specified limits. The ambient temperature range is -25°C to +75°C. With 0.3% line regulation and 0.5% load regulation, these converters are applicable for demanding applications without requiring post-regulation. Dimensions are compact with 50.9x25.5x15.6mm for single or 53.5x27.8x15.6mm for dual output models. The MTBF (+25°C) to MIL-HDBK 217F is specified at >400.000 hours. The RAC06-series is also available with flying leads.

Other Specifications:

Our new micro-converters are 3kVAC/1 min. isolated, feature an integrated input filter to EN 55022/EN 55024 Class B EMV and are short circuit and over-load protected. All converters are CE and UL certified (EN 60950-1/UL 60950-1). The warranty is 3 years.

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…


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.
