UPS For Lift Application

Have you ever considered how you would evacuate people from a multistorey building in case of power failure? Do you have responsibility for people coming and going from public buildings? If you do, you need to consider how you’re going to handle evacuation in the event of an extended power failure and are not equipped with a standby generator. It doesn’t need to be a dramatic situation just an extended power outage. Lifts by default should have the means to travel to the closest floor and open their doors so occupants can leave in the case of power failure. That is fine for able-bodied persons who are capable of continuing evacuation using the staircase. How would you evacuate people with mobility issues? A simple cost-effective solution is to power lift through UPS, however, it may not be as simple as it seems. Suppliers and installers of UPS systems intended to support lifts should be aware that some lifts have regenerative braking, which generates a potentially damaging back–EMF onto the DC Bus within the UPS. Your duty of care If you have injured, incapacitated or disabled people in your building you need to have a plan in place to evacuate in any circumstance. This applies to any public building, including: Office buildings Schools and universities Libraries & Hospitals Taurus ON-Line AC UPS 10kVA-80kVA Read more Harnessing Energy with Taurus Series With Helios Power Solutions 3-phase Taurus UPS, you obtain the maximum reuse of reinjected energy, with consequent economic savings. Thanks to its dedicated lift function, Taurus connects the dummy load at the output with only a fully charged battery and absent mains. The results are brilliant. No need to have an oversized UPS and battery; extremely rare use of the dummy load and extended battery life. In particular, the main Taurus Lift functions are: Built-in dry contact to pilot the external contactor of the dummy load Dummy load connected in parallel to the load at the output of the UPS for easy installation Function can be activated by software No need to have an oversized UPS and battery to absorb the energy back-feed Batteries are always protected – operating within the pre-set limits https://www.youtube.com/watch?v=0ANwjSYc8LM&embeds_referring_euri=https%3A%2F%2Fwww.heliosps.com.au%2F&feature=emb_logo If you have any questions about utilising UPS for lift backup, please get in touch with our AC UPS Expert.

Helios Power Solutions Group is Three Years Old but with more than 100 Years of Combined Experience

Although it is hard for us to believe, the amalgamation of five companies under the Helios name and the establishment of an operation in Asia is now three years old. After more than 30 years of successful business in their own right, Innovative Energies, Inline Components and Enertec Power in New Zealand, and Amtex Electronics in Australia are now fully operational and integrated under the Helios brand in New Zealand and Australia, and Helios Asia is up, running and growing, based in Singapore. We are unique and unbeatable in the power conversion market because we can design and supply a technically robust solution for pretty much any industrial power application. This can range from a small industrial-grade DC/DC converter, battery charger or UPS, to a complex custom-designed power solution for power stations, gas pipelines or remote communications facilities. Our point of difference is our team of experienced power engineers. They can guide you through the process, and if a standard product is not available, we can design and manufacture a custom solution in our Auckland and Sydney manufacturing operations. These systems can be factory approved tested at our premises, and delivered to site as a turnkey solution. Just as important, we have experienced service technicians and facilities locally to provide back up and support should you need it, and whenever you need it. When it all “hits the fan” at 2.00am in the morning, you will appreciate the value of this.Thanks to our customers in Australia, New Zealand,Pacific Islands, Middle East & Asia for being part of this transition process. We will continue endeavouring to offer the best technical advice and solutions in the DC & AC Power Conversion World.

DC Power Supplies for DC Motors

How to select the right DC Power Supply for DC Motors? Motors, solenoids and relay controls require higher levels of current during start-up than they do for continuous operation. Mechanical failures such as motor stalls or due friction can increase the current draw dramatically. When designing or installing a DC motor supply, many factors such as back up, loading, speed variation, regenerative current and others should be considered. At Helios, we recommend that when selecting a power supply for your DC Motor, you should be aware of at least  the following aspects: Maximum Current required: High currents drawn above the motor rating can cause motor seizures, overloads and motor failures causing heating and not rotating. Constant Current limit: Not one that goes into hiccup mode this means that, should an overload occur, the output current stays at its limit point, and the output voltage reduces towards zero. Typically, the supply will automatically return to its normal output voltage when the overload condition is no longer present.ie when the motor is running normally. Output diode required: To prevent the power supply being damaged by reverse voltage spikes which occur when the supply is turned off and the motor is slowing down. To illustrate, here are examples for brushed dc motor and a brushless dc motor Brushed DC motors With this type of motor, the magnets are stationary and the coil rotates.  Electricity is transferred to the rotating coil by the use of “brushes”. The advantages of this type of motor are low initial cost and easy speed control. When the power is interrupted, the motor coil will act like an inductor and will try to continue to produce current, effectively becoming an inverted voltage source.  This will apply a reverse polarity to the power supply and can cause damage to the motor.  (Back EMF – Electro-Magnetic Flux) By using a diode, as shown below, the diode provides a current path for the reverse motor current and will clamp the reverse voltage to a level no greater than the forward voltage drop of the diode.  This protects the power supply’s output capacitors and other components from being stressed by the reverse voltage. Brushless DC motors Brushless DC motors, often referred to as BDCMs or BLDC motors, have permanent magnets that rotate and a fixed armature Although this option can be more expensive, providing higher reliability in the long term having no brushes or commutator wear plus enabling position control to be more accurate. When the motor is turned off or reversed, it will act as a generator and produce a high voltage spike.  This spike can cause the power supply’s overvoltage protection to trip, shutting down the unit. By using a diode in series with the output, as shown below, the spike will be blocked from interfering with the power supply. [1]   [1] Posted by Power Guy http://power-topics.blogspot.com/ Variable Speed – DC Motors Changing the voltage applied to the armature of the motor is one of the ways to better control DC Motor’s speed. We suggest for a specific application to use a power supply with a programable output voltage. As every application is different and there are many factors to be considered that can or may affect the final design.  Contact Our Team of engineers if you require more information about how to power and backup your DC Motor.If you require more information about how to power and backup your DC motor please use our contact page or call +61 2 7200 9200 DC Power Supplies for DC Motors HDS1500 Programmable AC-DC Power Supply: 1500W $1,852.00 Select options HDS800 Programmable AC/DC Power Supplies: 800W $730.00 – $965.00 Select options SWS600L – SWS1000L – AC/DC Single Output: 600W – 1000W Read more Sold out HDS3000 – AC/DC Programmable Power Supply : 3000W $3,613.00 Select options Sold out SR 100HL – AC/DC Power Supply 100W with Comms Read more Sold out SR 250HL – AC/DC Power Supply 250W with Comms Read more Diodes & Redundancy Modules DRM40 DIN Rail Mount Redundancy Module 20A & 40A $139.00 Select options P Series Output Diode For Parallel & Redundancy Applications up to 400V Read more
