Efficient, High Brightness LED Controller Introduced by Saelig

Saelig Company Inc. has introduced the LED-Warrior01 modules, a LED control module designed to provide constant current output for driving up to 7 high brightness LEDs. These step-down power supply modules provide 350 mA, 700 mA, or 1000 mA for LEDs, with a maximum output power of 24W and an efficiency of up to 95 % from input voltage of 7V to 30V.  LED-Warrior01 regulators can be used in a wide range of low voltage lighting applications with multiple LED groups.

LED brightness can be controlled with LED-Warrior01 modules via analog or PWM signals, and when the LEDs are switched off, the modules go into a low consumption standby mode, consuming less than 40 uA. A primary design goal for the LED-Warrior01 has been exceptional reliability by avoiding components like electrolytic capacitors, making sure the electronics perform to specification longer than the LED. Primary design constraints for the LED-Warrior01 have been energy efficiency, reliability, and cost/performance ratio. The resulting product is a low-cost, point-of-load regulator board that is compact (1” x 0.8”) and allows easy integration into lighting solutions. The low input voltage design allows for use in existing low voltage installations, including on-board power in vehicles.

Recently, LEDs have become a viable alternative for general lighting applications. Compared to traditional light sources, LEDs offer a much longer life cycle and, in most cases, significantly better energy efficiency. But the technical hurdles in designing LED-based luminaires are higher than with traditional light sources. Designing reliable electronics to efficiently drive the LEDs is often a challenge for lighting manufacturers. But LED-Warrior01 regulators offer a simple, easy solution for most low voltage LED lighting situations.

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.
