Save on refrigeration freezers and ventilation. UST Power saves 8% to 15% on the power of your entire supermarket. When you place a UST power conditioner between the grid and your critical equipment, you can be assured that common electrical anomalies, of any intensity or duration, will be stopped and corrected within, depending on
your needs, one, two or three cycles and an efficiency of 99%. At an incomming voltage of 230V +/- 10%, the nominal output voltage can be set to 215V +/- 1%.

  1. 1. Save on refrigeration freezers and ventilation UST Power saves 8% to 15% on the power of your entire supermarket
  2. 2. Save 8% to 15% on the power for your entire supermarket with a payback period of less than 3 years. We reduce your electricity bill, extend the service life of your electric and electronic equipment and limit repair and maintenance costs. The power company has to feed extra voltage to the grid to guarantee that electricity is provided satisfactorily to all users. The incoming voltage can go up to more than 250 Volt, while you often only need 215 Volt. You still have to pay for the extra voltage. What’s more, your electrical equipment is loaded unnecessarily, which reduces the service life and increases the costs of mainte-nance and repair. UST manufactures a full line of industrial-grade power conditioners - electronic voltage regulators (EVR) with patented microprocessor-controlled tap switch-ing technology - that offer far more reliable power protection and energy saving. When you place a UST power conditioner between the grid and your critical equipment, you can be assured that common electrical anomalies, of any intensity or duration, will be stopped and corrected within, depending on your needs, one, two or three cycles and an efficiency of 99%. At an incomming voltage of 230V +/- 10%, the nominal output voltage can be set to 215V +/- 1%. The UST power conditioners com-bine the best qualities of typical mechanical and electronic voltage regulators while eliminating their weaknesses. Mechanical voltage regulators are valued for their high overload capacity and good voltage regula-tion, but these qualities are offset by their slow correction speed and the need for regular maintenance of moving parts. Similarly, electronic voltage regulators are known for their fast correction speed, but suffer from poor overload capacity. The UST power conditioners provide high overload capacity for loads with large inrush-current require-ments. At the same time, it provides consistent voltage regulation and fast correction without regular maintenance or moving parts. Within the last decade, UST power conditioners have proven capable of reliably and efficiently compensating for variations in incoming voltage. UST power conditioners minimize and balance variations in voltage to protect equipment, ensuring consis-tent voltage and saving money. Non-linear consumers frequently lead to serious problems with regard to power quality. Therefore, it makes sense to measure consumption levels and loads together with the general power data in the stores, collect the data and benchmark the stores with each other. Many loads in commercial facilities have inductive or mixed characteris-tics, such as: refrigeration systems and air conditioners. These types of electric devices include either a single phase or three phase induc-tive motor. When inductive motors work at nominal power level they are very efficient (typically >90%); however, in many cases these motors are oversized and are actually operated under partial load conditions. In this regime the inductive motor is inefficient, since the power factor is low and the working current is high - as a result, the motor produces more internal and network losses and emits more heat. For motors running at loads below the nominal, voltage reduction in the allowed range will change the motor working point and bring the motor to a more efficient position in the Load vs. Efficiency curve. A similar improvement can also be detected at the power factor. Increase of the power factor will actually reduce the working currents and reduce conduction losses in the facility electric network. Stable output voltage (215V +/- 1%). Fast response time of up to 20 ms (no risk of undervoltage) and an efficiency of 99%.

  3. 3. We Save Power performs energy audits including all aspects of power quality and EMC. Based on measurements, we can translate our knowledge and under-standing of electrical installations, electrical equipment and electronics, motor- and drive-technology into a clear reporting about the ‘health’ of your power supply, including advice for any necessary improvement. Neither power control and power quality protection, nor the lack of it, are without cost. An important part of assessing power quality related costs is determining what specifically is being affected and where, or in what aspects of business operations, these costs show up. The benefits of good power control and power quality vary from energy savings up to damage protection. Prevention is relatively cheap ranging from simple good practice to the installation of support equipment.
