Roband Launches Power Supply For Defence Market

Roband Electronics has added the RO-MIL-2213 power supply to its compact military-specification DC-DC converter range. The RO-MIL-2213, which is supplied in 3.3V and 5V output versions, is capable of delivering a 20A output current from a 76.3 x 38.2 x 10.2mm package. The high-efficiency, high-power-density single-rail unit comprises an isolated, high-frequency, pulse-width-modulated push-pull converter. While it is specified to operate from a nominal 28V supply, this versatile power supply will accept an input-voltage range from 12-40V (5V output version) and 14.5-40V (3.3V output version).

Options include an 80V input-surge capability and a variant that will operate from an input as low as 9V. External synchronisation is also available as an option. The RO-MIL-2213 operates over the military temperature range without de-rating. It is unconditionally stable and does not require additional external components for correct operation. A remote-sense facility is provided to compensate for any voltage drop at the load due to the length of the power-supply leads. The converter is also equipped with a remote disable function. Both short-circuit and over-voltage protection is provided as standard.

The unit is housed in a machined aluminium enclosure, with a mounting flange configuration that has been designed to optimise thermal impedance and provide adequate vibration support. A PCB-mounting version is also available. Roband's converters are manufactured in accordance with the company's approved Quality Management System: BS EN ISO 9001:2000, BS EN 9100 and BS EN 9110. The RO-MIL-2213's wide input voltage range and surge capability ensure its suitability for MIL-STD-704 applications.

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.
