New Low Cost Switching Regulator for Less Than USD 1.98

The price for our new modular R-78E – switching regulator is so attractive that it no longer pays to manufacture them in house – not even for large quantities! Buying these modules saves time, development costs and avoids negative surprises, for example undesired radiation.

Low energy consumption has become a watch word, high energy consuming linear regulator are no longer an alternative. Their energy losses are usually 5 to 10 times higher than for the R-78E. It is therefore not surprising that they require cooling, whilst the R-78E does not need heat sinks. The slightly higher material costs of the switching regulator are usually amortized within a few months.

The new R-78E is pin-compatible with other 78-switching regulators and standard TO-220-linear regulators. This module is a cost effective, energy saving “drop-in” replacement. Its input range of 4:1 extends up to 28VDC and enables the operation of 24-industry standard bus systems, as well as 9V and 12V battery systems. The 5V/500mA output is regulated to <+/- 0,5%. The ripple is specified at <50mVpp.

The R-78E does not require external components, is short circuit-, overload- and against over heating, protected. Due to its high efficiency, operation in the industrial temperature range from -40°C to +85°C(+70°C without de-rating) is possible without heat sinks. Its SIP3-miniature case measures only 11,6 x 8,5 x 10,4mm.

This new “Low Cost” module covers most customer applications and makes no compromises with respect to quality and reliability. The warranty covers the full 3 years RECOM-standard. The R-78E is currently the cheapest switching regulator on the market and with its good specifications a viable economic alternative to discrete solutions. Its available ex stock from all leading distributors.

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

How LVDT Pressure Sensors Work?

Image
Pressure sensors - commonly referred to as pressure transducers, pressure transmitters, pressure indicators or pressure switches - are used to measure the pressure of gases and liquids (fluids). Pressure is an expression of the force and is normally stated in terms of force per unit area. A pressure sensor will generate an electrical signal relating to the pressure imposed. This signal is either analogue or digital in more modern designs, although optical, visual and auditory signals are also common. Industrial pressure transducers normally have a diaphragm type design that uses strain gauges, which are either bonded to, or diffused into it, with the strain gauges acting as resistive elements. Under the pressure-induced strain, the resistive values change. In capacitive technology, the pressure diaphragm is a single plate of a capacitor that

Top 5 Applications for Inductive Sensors on Packaging Machines

Image
Amid the multitude of advanced technologies being integrated into automated packaging operations today, one of the most reliable and versatile component s - inductive sensors - have been holding their own for decades. These simple sensors pack a big punch for OEMs and end users alike. We have compiled a list of the top five places where inductive sensors can positively impact productivity. Many factors make inductive sensing attractive to modern packaging applications. Because the sensor uses inductive variations in an internally generated magnetic field to detect the presence of metallic objects, there is no need for the sensor to physically contact the target itself. That feature alone offers a host of advantages - consistent performance fo r a variety of product or machine position and counting applications in harsh and sanitary environments, resistance to dirt and other substances, adaptability to high - speed functions , and many more.   SICK Inductive Proximity Sensor
