TDK-Lambda Offers General-Purpose Power Supplies

TDK-Lambda EMEA has added a 200W model to its single-output LS series of general-purpose power supplies for budget-conscious applications. Models in the series now cover 25W to 200W. The LS200 can fit into a 1U rack; it has a universal input range of 85-264VAC (47-63Hz) with PFC meeting EN61000-3-2, 3, and can withstand a 300VAC surge for five seconds. Over-current with constant current limiting, over-voltage and over-temperature protection circuitry are standard features of the LS200, as well as remote on/off signal, green LED 'on' indicator and remote sensing.

Available either enclosed with low-noise fan or U-channel style with convection or customer airflow cooling, the efficient design of the LS200 achieves good thermal balance and 299K hours MTBF. Nominal output voltages range from 3.3-48VDC, delivering currents of up to 40A. To accommodate non-standard system voltages, the LS200 is user-adjustable by up to -10/+20 per cent (for 12V, 24V and 48V). Offered with an extended -25C to +70C operating temperature range, the LS200 thermal design enables full power output up to 50C and 60 per cent output power at 70C.

Furthermore, the 24V and 36V output voltage models have 250W peak power capability. As well as meeting EN55011/EN55022 class B conducted and radiated emissions, LS200 meets UL/IEC 60950-1 edition two safety approvals and carries the CE mark. The LS200 series comes with a three-year warranty. Size is 199 x 98 x 41mm.

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.
