60-Net UPS Provides 10-20kVA Of Back-Up Power

Chloride has launched the 60-Net, a UPS designed to provide between 10kVA and 20kVA of back-up power. The 60-Net offers double conversion technology, previously available only to larger data centres. With a footprint of just 0.27m2, it is even suitable for small IT facilities. Built-in batteries and a modular design mean that the 60-Net offers a minimum of 30 minutes of guaranteed power and desktop-style usability.

Its near-unity input power factor (better than 0.99) ensures that it draws the minimum possible input current for any given system load. This characteristic, together with a total harmonic distortion (THDi) of less than five per cent, makes it suitable for operating with an existing diesel generator without the need for oversizing. The 60-Net can support all types of balanced three-phase loads and unbalanced loads.

Rob Tanzer, Chloride's technical support manager, said: 'Up to eight units can be set up in parallel to protect growing critical loads, while the 60-Net is unique in its ability to supply uninterrupted power to any leading or lagging load power factor within its nominal rating. 'This means that the unit could support any future type of load - that may have some unknown electrical characteristic - without the user paying a price in terms of decreased efficiency or the need to buy additional equipment,' he added.

The 60-Net is based on Chloride's double conversion technology with a DSP-based IGBT inverter. The output can be used as a conventional three-phase supply or each output phase can be individually used to support 230V one-phase critical equipment loads. According to the company, the 60-Net has an optimised trade-off between harmonic rejection and efficiency.

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.
