MEGA Electronics Inc. 0.5 Amp and 1.0Amp switching regulators are ideally suite to replace 78xx linear regulators and are pin compatible.  With efficiencies up to 96 per cent very little energy is wasted as heat, eliminating the need for heat sinks and drastically reducing overall weight.  In addition to wide input voltage ranges, the regulators include a thermal shutdown, short circuit protection with continuous automatic recovery and low ripple and noise.  Normal operating temperatures are from -40C to +85C ambient and +100C case temperatures of the fully encapsulated regulator.   Recommended for use as a stable source of DC output voltage from a wide input DC range such as from batteries.  The low weight and space requirement make this an ideal, cost effective alternative to the linear 78xx.  As standard stock items the parts are readily available.   www.megaelectronics.com

PaceControls LLC is now making its energy efficiency and demand response technology available in Canada. The PaceController retrofit controllers are proven and patented to save 10-20 per cent or more on energy costs for heating, air conditioning and refrigeration and will maintain full end use performance. The engineers at PaceControls have developed this tool to extend the service life of older equipment and improve on new equipment by the use of patented technology to improve efficiency in methods OEMs have not yet agreed to purchase. Why replace capital equipment when you can retrofit for less. This extremely successful technology for saving energy is now stepping into the wireless age by working with Wellspring Wireless, a leader in ZigBee building automation wireless networks, and the next generation retrofit controller will be available in Canada this summer. www.pacecontrols.com

LEDtronics introduces an addition to its line of drop-in replacement MR16-styled LED bulbs: high-powered Three Watt LED MR16 bulbs. These new 3Watt MR16 LED bulbs have two big advantages over other MR16 LED bulbs. First, they are engineered to handle the variations in voltages that may accompany "noisy" or "dirty" AC or DC power supplies, eliminating potential burnout from incoming voltage that is higher than the lamp's capacity. Second, the new 3 Watt MR16 bulbs eliminate the need to stock a variety of LED MR16 bulbs to coordinate with different voltages that power supplies of 12 Volt AC/DC - 24 Volt DC may present, simplifying procurement and inventory procedures. www.ledtronics.com

Canada can achieve deep greenhouse gas (GHG) emission reductions by 2050, but only by putting a price on carbon emissions throughout the entire Canadian economy beginning as soon as possible, concludes the National Round Table on the Environment and the Economy (NRTEE) in a new climate change report released Monday, January 7, entitled Getting to 2050: Canada’s Transition to a Low-emission Future.

LEDtronics says its latest generation of R30 LED Reflector spotlight bulbs combine advanced light emitting diode (LED) technologies, standard 25mm Edison bases and light optimizing designs to produce vivid light. R30 LED bulbs are available in five light emitting angles (15°, 20°, 30°, 40° and 95°) and in 120 volts AC. Other voltages from 12V to 240V — AC or DC —are available for qualified customers. With a power draw of only 4.5 Watts, the savings add up quickly, says the company. R30 LED bulbs are designed to perform well in systems subjected to voltage dips or surges. Integrated current-limited resistors ensure that no circuit modifications are required. Solid-state design renders LEDs impervious to electrical and mechanical shock, vibration, frequent switching and environmental extremes. With an average lifespan of 100,000-plus hours (11 years)—up to 50,000 hours for white LEDs—LED bulbs operate reliably year after year and are appropriate for many energy-saving uses, says the company. www.ledtronics.com

Schneider Electric Canada has introduced Simply Smart industrial ac drives for 3-phase asynchronous motors from 0.5 to 900 hp. The Altivar 71 model, dedicated to all industrial applications, is complemented by the Altivar 61, for pumps and fans. Altivar 71 can deliver up to 220% overtorque; 130% for Altivar 61. Both drives offer flux vector control (FVC) with or without sensor, online auto-tuning, speed or torque control, output frequency up to 1000 Hz and an energy saving function for pump and fan applications. One drive can independently control up to 3 motors, units withstand voltage drops of up to -50%, RF interference and operating temperatures up to 50ºC (without derating).   www.schneider-electric.ca

Sullair Corp. introduced the 1100e, 1500e and 1800e encapsulated series of compressors to its established line of industrial air compressors. The compressors offer 15-, 20- and 25-horsepower capability. The compressors are available with Sullair's Variable Speed Drive (VSD), which can efficiently adjust to changes in air demand, says the company. With the VSD, these compressors deliver greater energy efficiency, improved operating consistency and lower lifecycle costs, says the company. Sullair's compressors also incorporate many features that reduce noise levels. The air-end and motor are mounted on rubber isolators, intake and exhaust louvres have been insulated and every machine comes standard with a fully insulated enclosure. This allows Sullair's 1100e, 1500e and 1800e compressors to operate at noise levels as low as 66 dba, says the company. www.sullair.com

GE’s Starcoat SXL lamps provide the same light as standard F32T8 lamps but promise longer life, offering 36,000 hours of life at 12 hours per start on rapid-start ballasts. This decreases burnouts and reduces labour and disposal costs because of longer periods between relamping. For information, visit: www.gelighting.com

Invensys’ new Robertshaw i-Series programmable thermostats can be set up in half the time than some other models because of their installation ‘wizard’ feature. The Setup Wizard on models 9701i2 and 9725i2 saves contractors installation time and also makes programming easier for homeowners by navigating users through a series of menu-driven screens with simple instructions in English, French or Spanish. In addition to the wizard, Invensys has added numerous features, such as automated time adjustment for Daylight Saving Time and indoor air quality reminders. Also new is adjustable backlighting that can be used at all times or only while programming, and three levels of security that allow homeowners to protect against unwanted changes. Users can also control the temperature via remote sensor when these models are used with Robertshaw remote indoor/outdoor sensors. For information, visit:. www.icca.invensys.com
