Development of the HWS-L/BAT Series of Power Supply Units for Charging Secondary Batteries.

TDK Corporation (President: Takehiro Kamigama, Head Office: Nihonbashi, Chuoku, Tokyo) announces that it has developed the HWS-L/BAT series of power supply units for charging secondary batteries available as an option for TDK-Lambda's HWS series of standard power supplies for industrial equipment. The new series is available in 600W and 1000W types (4 models in total). It has been marketed by TDK-Lambda Corporation (President: Yoshiaki Hirota, Head Office: Nihonbashi, Chuoku, Tokyo). Orders can be placed from July 1, 2012.

Since the Great East Japan Earthquake, there have been increasing concerns over power loss at the time of disasters such as mega earthquakes or shortage of electricity supply during the summer season. It is vital for all industries to secure electricity in emergency situations And, consequently, there is an increasing need for power backup systems using secondary batteries. Responding to such requirements, TDK has developed the “HWS-L/BAT series” of constant current power supplies for small to medium capacity secondary batteries based on the existing “HWS series” already well established in the industrial equipment market. They can also operate in parallel mode so that a wide range of battery capacities can be handled.

The HWS-L/BAT series constant current power supplies have been developed from the “HWS series” products that are already well established in the industrial equipment market. They are optimal for charging small to medium capacity secondary batteries in both constant current and constant voltage charge modes. In addition, charge current and maximum charge voltage can be preset at any level within the range allowed by the specifications. A charger configuration can easily be built by combining backflow prevention diodes and circuitry to stop the charge operation at the time of battery failure. The HWS-L/BAT series power supplies, together with the EVA series power supplies for medium to large capacity applications that have been recently released, can meet a wide range of customer requirements.

Main features
  •     Constant current power supply whose current and maximum charge voltage can be adjusted by the embedded trimmer.
  •     Capable of handling constant current and constant voltage charging. Optimal for charging many kinds of rechargeable batteries.
  •     Capable of handling both 24V and 48V secondary batteries. Available in 600W and 1,000W types, total 4 models.
  •     Parallel operation
  •     Small form factor just like the HWS series

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.
