Ipeco Electronics adds integral ‘hold-up’ to its 3U VPX power supplies
I
World’s most energy efficient digital temperature sensor
M
MS Electronics has introduced a new range of digital temperature sensors from Smartec. The
SMT172 is an ultra-low power, fully calibrated, high accuracy digital sensor. Using the most recent advances in silicon temperature sensing technology, the SMT172 has applied sophisticated IC design techniques and high-precision calibration methods, to achieve an absolute inaccuracy of less than 0.25ºC in the range of -10ºC to 100 ºC.
Full
temperature range is -45ºC to 130ºC. The sensor operates with a supply voltage from 2.7 to 5.5V. The typical active current of only 60uA, high speed conversion over 4000 outputs per second (room temperature) and extremely low noise, makes this the most energy efficient temperature sensor in the world. The SMT172 has a pulse width modulated output signal, where the duty cycle is proportional to the measured temperature. The sensor can connect directly to a Micro-processor without an Analog-to-Digital Converter.

peco Electronics, specialists in the design,
development and
manufacture of high-reliability power solutions for aerospace and defence applications, has extended its 3U VPX range with the addition of an integral hold-up capability to its P47 and VITA 62 connector-fitted power supply units (PSUs). Integral hold-up is of immense benefit to engineers designing space-constrained systems which must be able to tolerate brief losses of input power; but in which there is no room for separate hold-up cards/units. In addition, Ipeco’s P47 connector-fitted PSUs are now available with an integral current- limited fan supply output with EMC filter; also of great benefit to systems designers. Ipeco’s 3U VPX PSUs accept steady state DC inputs, in the range 18 to 32V, and offer the following six DC outputs: 3.3, 5, -12 and 12V plus 3.3 and 12V auxiliaries; when fitted with a VITA 62 connector. In addition to being subjected to Ipeco’s rigorous in-house verification processes, several of the company’s 3U VPX PSUs have also been through military customer integration and qualification programmes; proving their operational integrity and reliability in harsh environments. With the design IP resting firmly with Ipeco, and without ITAR restrictions, several PSUs are available as commercial- off-the-shelf (COTS) or modified off-the-shelf (MOTS) units. For example, the P1324 3U VPX is available now as a COTS unit. Fitted with a P47 connector, the P1324 has three DC outputs - namely 3.3, 5 and 12V - and provides an overall continuous output power of 200W (when operating at 85oC wedge lock temperature). The unit, and an associated filter, meet the requirements of Def Stan 61-5 (part 6), including the survival of electrical equipment when subjected to a load dump of 174V for 350mS. Though designed for a tracked-vehicle, the P1324 is also suitable for aerospace and marine applications.

New range of Hipot and Insulation Resistance testers
T
elonic Instruments have introduced a new range of Hipot (Flash) and Insulation Resistance testers manufactured by Japan based Kikusui. Designated the TOS5300 the three models in the range are designed for use in Withstanding Voltage and Insulation Resistance testing to help ensure the safety of Electrical / Electronic components / equipment. Incorporating and innovative PWM amplifier that achieves high stability and has an input voltage regulation of.3%. The series offer rise and fall time control of the test voltage and a stable output which is unaffected by mains voltage variations, plus the ability to select 50 or 60Hz test frequency. Upper and lower current limits can be set within the range of 0.01mA to 110mA in AC mode and 0.01mA to 11mA in DC mode. AC test voltage is settable from 0.05kV to 5kV. D.C test voltages can be varied from 0 to 6kV. All models will operate from any global AC input voltages and frequencies; and are equipped with a USB interface.

KW’s metal enclosures division METCASE is pioneering the use of digital printing for front
panels, rack cases and instrument housings – saving customers time and money. METCASE’s new state of the art digital technology means legends, logos and complex photo quality graphics can be printed on front panels and enclosures quickly and easily. METCASE can print in full colour CMYK up to 1,800 x 1,800 dpi on painted or anodised metal surfaces (and plastics) with all different kinds of textures. Hard UV ink provides excellent scratch resistance and the surfaces are also lacquered for added protection. Digital printing is significantly faster than traditional silk screen printing and more cost effective because there are no expensive tooling costs – ideal for low volumes. Printing is carried out on a large A2 flatbed area so multiple panels or cases can be printed at once, speeding up the process still further. The maximum object height is 150 mm. Customers need only email METCASE a maximum resolution PDF or EPS file – or a DWG/DXF CAD file including the print details.
