DC-DC Converter Modules: HNDS/HNAS Series

Shindengen Electric Manufacturing Co., Ltd. (headquartered in Otemachi, Chiyoda-ku, Tokyo, Japan) imagined "a design to save energy easily just by putting it on top" when we developed the two types of non-insulating step-down DC-DC converter modules called the HNDS series and HNAS series.March 2009 marks the start of mass production, with over 1 million shipments expected in the first year, mainly to the industrial device market.

    * Designed to save energy easily just by putting on top!
    * HNDS series supports 12 V/24 V-type input
    * HNAS series supports 3.3 V/5 V-type input
    * Supports high-current (3 A) output
    * Incorporates comprehensive protection functions
    * Full range of mounting variations

In recent years, as momentum for protection of the global environment rises, energy-saving demands have intensified for devices of all kinds, not just products for consumers. Likewise, the market for industrial devices requires cuts in power consumption. To improve response speed and lower power consumption in memory and system LSIs used in industrial device control, etc., leaps are being made in lowering voltage and raising current. Power specifications, accordingly, grow increasingly diverse and complex. However, as faster product development is demanded of power design, it is becoming impossible to devote adequate time to consideration. Therefore, a number of cases can be seen in which the dropper method is used despite its low conversion efficiency because it is easy to design with, one factor slowing the movement towards energy conservation. We, however, have developed the concept of “a design to save energy easily just by putting it on top”into the non-insulating step-down DC-DC converter module HNDS series and HNAS series. It eliminates design headaches while helping to save energy with high-efficiency power. We have 3 mounting variations, considerate of the details of power designers' needs.

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
