AC/DC Power Supplies Are Medically Approved

TDK-Lambda has introduced the NVM175 range of medically approved AC/DC power supplies. Combining 4.5kVAC reinforced input-to-output isolation with dual fusing and an output-to-ground isolation of 1,500VAC, the NVM175 meets UL/EN/IEC60601-1 and is said to be suitable for use in BF-type medical applications. Offered in a 5 x 3in footprint with less than 1U height, the NVM175 supplies have universal AC input and are rated at 180W at 50C with customer air.

Leakage current is less than 200uA at 264VAC/63Hz surpassing worldwide medical equipment requirements. It is equally suitable for many other applications including broadcast, instrumentation, routers, servers and security networks, as well as ATE and automation equipment. The NVM175 is available with either 12V or 24V output voltage (with 12V/0.2A standby). The NVM175 meets TDK-Lambda's design brief for environmentally responsible products by achieving up to 90 per cent efficiency, less than 1W standby power and RoHS and Reach compliance.

Other standard features include a power-good signal, remote on/off, remote sense and protection from over-current, over-voltage and over-temperature conditions. Products in the TDK-Lambda NVM175 range meet Class B conducted and radiated EMC EN55011 and EN55022. All models have TDK-Lambda's three-year warranty, as well as EN/IEC/UL/CSA 60601-1, EN/IEC/UL/CSA60950-1 and CE approvals.

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.
