Power Supplies Can Be Provided In 2U Rack Mount

Safety Power has launched a range of high-quality 3,000W analogue power supplies that can be supplied in 2U rack mount or as an installation unit for mounting-board assembly applications. The VE3PUI is available in six single-output models, offering DC voltages from 0 to 30V at 0 to 125A, 0 to 52V at 0 to 75A, 0 to 60V at 0 to 63A, 0 to 90V at 0 to 42A, 0 to 150V at 0 to 25A and 0 to 300V at 0 to 12.5A. Input is 415V AC, three-phase, 45 to 66Hz.

The supplies offer constant-voltage, constant-current and constant-power modes programmed via 0 to 5V analogue signal with monitoring for voltage, current and power via standardised-value 0 to 5V analogue-signal outputs from front-panel measuring sockets. Standard features include remote on/off and power-fail (PF) signal, and each power supply is fitted with quick-release coded connectors for the mains and outputs, to ensure correct connection. Options include a separate programming and monitoring interface via a D-sub connector on the rear panel.

This includes PF signal, load-share (LS) bus, remote on/off, over-temperature alarm, voltage and current programming (0 to 5V DC), and voltage and current read back (0 to 5V DC). A green, back-lit display showing voltage and current can be fitted if required. Measuring 436 x 284 x 86mm, each VE3PUI power supply is designed to meet EN60950 and EN55011/22 class B standards, and comes with a three-year warranty as standard, plus a 48hr burn-in test to ensure high reliability.

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.
