New high performance power supplies ready to power Industry 4.0
P
owerbox, one of Europe’s largest power supply companies and a leading force for four decades in optimising power solutions for demanding applications, introduces four new power supplies designed to power Industry 4.0 applications. As part of Powerbox Industrial Line, the four series are based on the latest power switching technologies; LLC, synchronous rectification, active PFC, low leakage current and energy optimisation. From 80W up to 400W, the OBM33, OBM35, OBP37 and OBP38 deliver single output voltages from 12V to 48V suitable for the new generation of applications deployed in Industry 4.0 applications. The new series are designed and optimised for high performance in industrial applications. Industry 4.0 goes live and over the
Internet of Things, cyber-physical industrial systems will communicate and cooperate with each other and with humans in real time and via the Internet of Services. The very high level of interaction within Industry 4.0 will require efficient and reliable power supplies to guarantee all-time-on operation and no latency in communication, which the new Powerbox series OBM33, OBM35, OBP37 and OBP38 have been designed. Preserving energy is very important and
the products have been developed for high performance, low power dissipation and long lifetime. The OBM33, OBM35, OBP37 and OBP38 utilise an LLC half bridge topology, complemented by synchronous rectification and low standby power consumption. These technologies contribute to characteristics such as high efficiency (up to 93 per cent) high energy density, high peak output current but also very low power consumption at no load, below 0.5W and below 1W when using the Power Fail Detect signal.
The launch includes more than 28 models delivering a single output voltage of 12V, 15V, 18V, 24V, 30V, 36V and 48V within a power range of 80W to 400W. Combining efficient topology and optimised layout for EMI performance, the OBM33, OBM35, OBP37 and OBP38 meet and surpass EN55022B radiated and conducted Class B. The units are built to sustain industrial environments such as surges of ±1KV differential, 2KV common; magnetic field immunity of 1A/m, conducted immunity 3Vrms ; fast transient/burst 1KV ; ESD ±8KV air and 4KV contact.
The fourth industrial evolution is rapidly expanding around the world, requiring power supplies to meet regional line voltages and be able to operate in unstable power grids. With an input voltage of 90 to 264 VAC and line frequency of 47 to 63Hz, the OBM33, OBM35, OBP37 and OBP38 will reassure end users their systems operate in all regions with the highest performance and no disruption. “Internet of Things is everywhere and Industry 4.0 happening faster than expected. In that environment, business continuation and energy saving is a must, requiring power supplies designed to meet demanding and complex requirements,” says Martin Fredmark, vice president, product management. “The new series include a number of technical innovations contributing to reduce power consumption and to offer a high degree of flexibility to systems architects.” Considering safety, the range of applications deployed in the Industry 4.0 require power supplies to meet high isolation voltages. The new series can withstand 3000 VAC (4000 VAC for the OBM33) input to output, 1500 VAC input to ground and 500 VAC output to ground.
Designed to provide designers with safety margins at 264 VAC and 63 Hz, the maximum leakage current is below 275
µA, which is very unique for an industrial power supply and four times lower than
normal average. Accommodating system integration
requirements, the new series include different mechanical options, open frame, L and U bracket & fully enclosed with fan. The OBM33 (80-150W) is available in 2 x 4in footprint (1.3in low profile). The OBM35 (200W) fits into a 3 x 5in footprint (1.5in height) and available in U- bracket or fully enclosed. Addressing a very large segment, the OBP37 (300W) has a 3 x 6in footprint (1.5in height) and available in open-frame, L-bracket & fully enclosed with fan. The OBP38 (400W) has a 4 x 7in footprint (1.58in height) and packaged in U-bracket or fully enclosed with fan.
Products can be operated from -10°C to +70°C. Without extra cooling, up to 75 per cent of the maximum power is available. Additional forced air cooling will allow 100 per cent power up to 50°C, then a slight power derating will allow operation up to 70°C.
The new series include short circuit
protection, over-voltage and over- temperature protection. Depending on the model, additional features such as power fail detect (PFD) signal, output voltage inhibit, DC OK and PS OFF are available. At full load and 25°C ambient, based on the calculation method MIL-HDBK-217F, the OBM33, OBM35, OBP37 and OBP38 MTBF reach up to 300,000 hours. Products comply to RoHS requirement and designed to minimise environmental impact.
www.prbx.com RS Components adds APEM Halo LED illuminated indicators to portfolio R
S Components is first to market with a new range of Halo LED illuminated indicators from APEM, a world-leading manufacturer of man- machine interfaces. The QH indicators target diverse applications, and are of special interest to engineers designing emergency stop buttons, door release systems in public buildings and offices, and in a variety of automation systems. The QH series provides impressive, stylish and intuitive visual feedback with optimal high-quality LED light output. The functional design allows it to be easily mounted as a status indicator for interior and exterior use, and on both new and after market applications installation is both quick and easy.
QH Halo indicators mount seamlessly with a wide variety of switches,

including anti-vandal, pushbutton, rotary and key switches, enabling focused interaction between human touch and machine. The series is designed to be highly versatile and supports a variety of cut-outs from 16mm to 22mm with a choice of body and lens colours. An outstanding feature of the QH series is its exceptional light output provided by the 12 single and dual coloured hyper- bright LEDs. Other features of the QH Halo LED indicators include: sealing to IP67 standards; operation over the –40 to +70°C temperature range; zero depth from behind the panel; supply voltage of 12 to 24VDC; and 200mm 26AWG UL1061 wire termination.
