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.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

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...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
