CUI Introduces the Industry’s First No-Bus Self Compensating Digital Point-of-Load Modules

CUI Inc releases the industry’s first self-compensating No-Bus digital point of load dc-dc module family. The modules are specifically designed for customers who value the efficiency and compensation advantages inherent in digital power but do not want to incorporate digital bus communication in their systems. The NSM2P series will allow customers to access many of the same features as a fully digital POL, however the access will be via header pins that will connect to a USB dongle and CUI’s Digital Power GUI. The designer can dynamically test and manipulate the desired functions within their system, monitor the results, and set the desired fault management functions. In production, the engineering header is pulled and the specified parameters are loaded into the module by CUI based on the customer’s specific requirement.

The NSM2P has the same features and functions of the recently announced NDM2P series without the need for a serial bus connection on the board, also offering true cycle-by-cycle self compensation, autonomously balancing the trade-offs between dynamic performance and system stability. With this feature, designers are able to bypass the traditional practice of building-in margins to account for factors such as component ageing, manufacturing variations, and temperature, which inevitably lead to higher component cost and longer design cycles. The NSM2P’s take full advantage of Powervation’s cycle by cycle self compensation feature, the module is able to dynamically set optimum stability in real time as conditions change.

Offering efficiencies above 93% at half load, the NSM2P series is available with an input range of 4.5~14 Vdc and a selectable output range of 0.6~3.3 Vdc in three compact DIP configurations; a 12 A version measuring 0.825 (L) X 0.500 (W) X 0.286 (H) in., a 25 A version measuring 1.01 x 0.54 x 0.32 in., and a 50 A version measuring 1.215 x 0.79 x 0.36 in. SMT and SIP versions will be available as well. Additional features include 1% Vout accuracy, precision ramp control, margining, and a multi-config pin that allows up to 8 configuration files to be stored in a single part number as well as a nested footprint between the three modules to support dual layout needs. The NSM2P modules are optimized for the complex needs in the low core voltages requirements of today’s most advanced chips.

“We pride ourselves in making digital power as simple and accessible as possible for engineers,” said Mark Adams, CUI’s Senior Vice President. "The NSM2P series will allow our customers to enjoy the flexibility and performance of digital power in a package that is even easier to design in than an analog point of load module," Adams concluded.

The NSM2P series the latest addition to CUI’s Novum® Advanced Power product line, which focuses solely on the design and development of leading edge power platforms. NSM2P engineering samples are available immediately for select customers.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
