Tonar Industries, a Mean Well fanchised distributor, announces news from Mean Well!

After the launch of SPU02 (2W) series, MEAN WELL introduced another 3W encapsulated packaging module type unregulated DC-DC converter ~ SPU03 series, to fulfill the low cost and low wattage related applications. With single-in-line package, the size of 3W converters has been widened slightly (0.77" x 0.30 "x 0.40") based on the original SPU02 case size (0.77 "x 0.28" x 0.40 "). In addition, SPU03 series possess up to 88% of high efficiency, hence, they can be operated by free air convection cooling from -40℃ to +90℃ ambient temperature. Equipped with standard pin assignment, this series feature with 3000VDC input / output isolation, low ripple noise, cost effective, CE/FCC compliance, and built-in short circuit protection, which are very suitable for industrial control, telecom/datacom, and distributed power architecture related applications.

Tonar Industries, a Mean Well franchised distributor, announces news from Mean Well!

MEAN WELL introduced new generation of 30W miniature single output regulated DC-DC converter with size of 2”x 1”x 0.44” ~ SKM30 series. Featuring with dual-in-line package, SKM30 series greatly reduce the size by 65.1% comparing to the current corresponding models of SDM30 (30W, 2”x 2”x 0.63”) and increase the working efficiency by 5~11%. Furthermore, compared to SDM30, the slim design makes it 30% lower in height, so that SKM30 can rank as the smallest DC-DC module type converters among the same wattage products in the market, which help system designers to solve the tough issue of space limitation.
With up-to date high frequency circuit design, SKM30 series possess up to 90% of high efficiency, therefore, they can be full load operated by free air convection cooling from -40℃ to +55℃ ambient temperature, and even up to +75℃ by derating the output load. Equipped with standard pin assignment, the new series feature with 2:1 wide input range, 1500VDC input / output isolation, short circuit / overload / input and output over voltage protections, low ripple noise, built-in remote ON/OFF control, and output trimming. In addition, the six-sided shield metal case can significantly enhance their EMC characteristics that make them comply with CE/FCC regulations without adding extra EMC suppression components. The fully encapsulated packaging can help SKM30 withstand the influence of dust and moisture in all kinds of harsh environment, which are very suitable for industrial control, telecom/datacom, and distributed power architecture related applications.

After launching SKA40 (40W) series, MEAN WELL continuous to introduce another 60W module type single output regulated DC-DC converter in size of 2”X2” ~ SKA60 series, for the growing demands of miniaturization and high power density applications. With dual-in-line packaging, these 60W converters are designed to comply with the standard pin assignment in the market. Standard features include 2:1 wide input range, 1500VDC input / output isolation, short circuit / overload / over voltage protections, low ripple noise, remote ON/OFF control, remote sense, and trimming output (±10%). In addition, without adding additional EMC suppression components, they can comply with CE / FCC Class A requirements.
With up-to date high efficiency circuit design, SKA60 series possess up to 93% of high efficiency. They can be full load operated without any heat-sink installed on the top and be cooled by free air convection from -40℃ to +55℃ ambient temperature, while even up to +70℃ by derating the output load. In addition, fully encapsulated packaging can help SKA60 have good heat dissipation ability and withstand the influence of dust and moisture in all kinds of harsh environment, which are very suitable for industrial control, telecom/datacom, or vehicle, vessel, back-up system and any application that use rechargeable batteries as the power source.

Simon presents the advantages of speed control for fans and the necessity of "handshaking" between fan and controller. Handshaking enables you to achieve optimum performance and energy-efficiency.
Speed control of fans offers many advantages, e.g.
- it reduces power
- it reduces noise
- it gives the performance needed
But because fans don't always obey fan laws, we need to "hand-shake control fans". This means that if we ask the fan to run at 50% speed then we would like the fan to tell us that it is doing 50% speed.
This is easily achieved using MODBUS RTU control of EC fans. This RS485 communication protocol allows full communication between the fan and the controller such the controller always knows the performance of the fan and indeed if the fan has a fault then the controller knows this as well. This is by far the best way of controlling fans and reduces their power consumption.
