Fluke Calibration 52120A Transconductance Amplifier Enables Accurate Calibration of a Broad High-Current Workload at Full Current Range

Fluke® Calibration introduces the 52120A Transconductance Amplifier, which expands calibration capabilities to a broad array of power and energy meters, clamp meters, current transformers and Rogowski coils (e.g. Fluke i6000 iFlex) up to 6000 A. Its industry-leading amplifier accuracy ensures precise calibration of devices.

The 52120A Transconductance Amplifier:
  • Supplies dc current to 100 A and ac current up to 120 A at accuracies to 140 ppm
  • Generates 3000 or 6000 A when using accessory coils
  • Can output up to 360 A when three amplifiers are connected in parallel
  • Has inductive drive capability of 1 mH and compliance voltage of 4.5 V
 The 52120A is designed for users whose ability to address their high-current calibration workload is limited by the output current, accuracy and drive capacity of their current test equipment. This includes calibration professionals in a calibration/standards lab or electrical utility, manufacturers of power/energy instrumentation and meters, as well as users of electrical test and measurement equipment.

The amplifier operates with any calibrator, signal generator or power supply capable of sourcing 2 V or 200 mA dc or ac, including the Fluke 5080A, 5500 and 5520 Series Multi-Product Calibrators, 5700 Series Multifunction Calibrators, and the 9100 Universal Calibration System. It can also operate in closed-loop mode, seamlessly communicating with Fluke Calibration 610X Electrical Power Standard to deliver enhanced 52120A accuracy.

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.
