//php echo do_shortcode(‘[responsivevoice_button voice=”US English Male” buttontext=”Listen to Post”]’) ?>

When the post-COVID-19 period comes, the DC-DC converter functions will span a variety of industries, together with shopper electronics, medical, telecom/datacom, industrial, automotive, and railway rolling inventory. The present development at practically 12% CAGR is accompanied by a robust push to avoid wasting house, time, and price towards software improvement. 

However moreover the factors of commercial calls for pushed by financial restoration, it’s additionally essential that suppliers have a historical past in continued product improvement in addition to a high quality administration system (QMS) in place that’s ideally licensed to globally acknowledged requirements. The provider should additionally supply a broad sufficient vary of merchandise to cater to altering undertaking designs in addition to altering software necessities.  

As a secure and energetic participant on this area, P-DUKE Know-how, Inc., based 1992, is one such firm that sells to Europe, the U.S., and Japan, capitalizing on investments in R&D, high quality management, and take a look at. With “world logistics, native administration”-driven operations, it has ISO 9001 and ISO 13485 certification for its QMS and ISO 14001 Environmental Administration Techniques in addition to security approvals from UL and CE.  

The corporate’s continued product improvement noticed the introduction of quite a few merchandise all through final yr, together with 2 W medical-grade and 12 W industrial DC-DC converters, extending the lineup to 300 W. Within the subsequent paragraphs, we’ll be taught extra practical particulars about P-DUKE’s merchandise. 

Rising converter portfolio 

P-DUKE has additional expanded the DC-DC energy module portfolio with the introduction of a number of merchandise for the railway, industrial/automation, medical, datacom/telecom, and take a look at & measurement functions. These embody HAE200W, MPQ60W, RED60W, RHD40W, and RCD30W, overlaying a large output energy vary of 30 to 200 W. 

All new converters supply a large 4:1 enter vary as indicated by the “W” for “extensive” within the mannequin numbers, implying the utmost enter voltage is 4X minimal. The brand new sequence all characteristic safety from overcurrent (OCP), overtemperature (OVT), output overvoltage (OVP), short-circuit (SCP), and enter undervoltage lockout (UVLO), and have a no-minimum load requirement. 

HAE200W: These 200 W remoted DC-DC converters meet the necessities of a number of functions, together with industrial and datacom/telecom, however are particularly certified for railway rolling inventory. Their EN 50155 certification covers, amongst numerous parameters, suitability of temperature, humidity, shock and vibration, and the EN 45545 compliance ensures hearth security in railway functions. Additionally they adjust to the brand new IEC/EN/UL 62368-1 commonplace that outdated the IEC 60950-1 for ICT and IEC 60065 for A/V gear and integrated Hazard-Primarily based Security Engineering (HBSE) ideas. Fashions with the “TF1” meeting possibility supply an built-in filter for EMI EN55032 Class-A compliance. 

Fashions on this sequence cowl enter voltage ranges of 8.5-36, 9-36, 16.5-75, and 43-160 VDC. The HAE200W gives output energy of as much as 255 W; effectivity as much as 93%; adjustable single-output voltages of three.3, 5, 12, 15, 24, 28, 48, and 53 VDC; I/O isolation voltage: as much as 3,000 VAC strengthened insulation; and working case temperature vary of -40°C to +115°C, all from a completely encapsulated, industrial-standard 2.4 x 2.28 x 0.5-inch half-brick footprint. Heatsink- or chassis-mounting choices are supplied. 

MPQ60W: This 60 W DC-DC converter targets medical functions, amongst others, with compliance to the IEC/EN 60601-1 / ES 60601-1 requirements. The IEC 60601-1 specification contains the Technique of Affected person Safety (MOPP), which at its most stringent safety, 2xMOPP, gives two layers of insulation, 4000 VAC of isolation, and eight mm creepage and clearance distances. The MPQ60W, with its 5000 VAC strengthened 2xMOPP insulation and <4.5 µA leakage present, gives the extent of energy provide isolation required by the very best of medical gear classifications — the CF (cardiac floating) kind for bodily contact with the affected person coronary heart. 

 Fashions within the sequence cowl enter ranges 9-36 VDC and 18-75 VDC. Different key specs embody: 

1. Working voltage: as much as 250 VAC 
2. Effectivity as much as 92.5% 
3. Leakage present: <4.5 µA 
4. Quarter-brick package deal 
5. Working altitude: as much as 5000 m 
6. Working temperature vary: -40°C to +105°C 

RED60W: A 60 W output sequence compliant with the EN 50155 and EN 45545-2 railway requirements and IEC/EN/UL 62368-1, it has fashions with enter ranges 9-36, 18-75, and 36-160 VDC and adjustable output voltages 3.3, 5, 5.1, 12, 15, 24, 48, 53, ±12, ±15, ±24 VDC. The RED60W gives as much as 94% effectivity and options 3000 VDC input-to-output isolation for 110 Vin and comes with a six-sided continuous-shield industry-standard 2 x 1 x 0.4-inch package deal.  

RHD40W: The 40 W fashions have a built-in EN 55032 EMI Class-A filter and supply 36-to-160 VDC enter vary, adjustable output voltages 5, 5.1, 12, 15, 24, ±12, ±15 VDC, and effectivity as much as 90%. Providing an working altitude as much as 5000 m and 3000 VAC input-to-output strengthened insulation, the sequence can also be licensed to EN 50155, EN 45545-2 railway requirements and IEC/ UL/ EN 62368-1. 

RCD30W: The 30 W sequence is available in a tiny 1 x 1-inch industry-standard package deal. Fashions supply enter voltage vary choices of 9-36, 18-75, and 36-160 VDC, adjustable output voltages 3.3, 5, 5.1, 12, 15, 24, 54, ±12, ±15, ±24 VDC, whereas all of them characteristic an working temperature of -40°C to +105°C with an elective -55°C decrease restrict and working altitude of as much as 5000 m. The sequence complies with EN 50155, EN 45545-2, and IEC/EN/UL 62368-1 requirements and gives choices for input-to-output isolation of 2250 VDC and 3000 VDC. 

Rising energy density 

Along with enhancing the efficiency of energy modules, measurement miniaturization can also be an essential pattern in associated designs. Nonetheless, larger thermal density has accompanied the upper energy density. It’s clearly an element that can’t be ignored which designers haven’t solely needed to look towards rising effectivity however putting in cooling infrastructure on key heat-generating parts and modules to shortly dissipate thermal power. 

To handle these challenges, P-DUKE has not solely addressed the requirement to shrink the scale of energy boards and PSUs but in addition upgraded lots of the heatsinks that match its industry-standard packages. The brand new heatsinks — HS, HC1, HC2, and HC3 — have fins which can be designed and sized for considerably higher temperature adaptation, as proven in Determine 4. 

The above is simply the general description of P-DUKE’s merchandise and their technical options. If you’re taken with discovering a DC-DC converter and heatsink answer on your software, please go to P-DUKE.com. P-DUKE additionally gives AC-DC energy provide options for industrial and medical functions within the vary of 15 W to 500 W.
