Input voltage single-phase input: 150V-260V three-phase input: 280V-430V can be customized special ultra-low-voltage output voltage line voltage: 380V phase voltage: 220V overvoltage protection 246V ± 4V frequency 50Hz / 60Hz efficiency ≥95% response rate ≤1S (voltage change 10%) Ambient temperature -10 ℃ ~ + 40 ℃ Insulation resistance ≥5MΩ electrical strength: Pressure> 2000VAC 1 minute without breakdown and flashover adaptive load resistive, inductive, capacitive and other occasions are adapted to the waveform distortion No additional waveform distortion protection with overvoltage, undervoltage, fault protection Overview: TND / TSD / SVC- series precision AC power supply with small size, waveform distortion, high voltage accuracy, reliable performance. Products at single-phase, three-phase two categories, there are two dozen standard models. Products are widely used in various devices need a stable power supply. Such as household appliances, modern office equipment, audio-visual systems, communication networks, control systems, sound engineering, medical and health equipment, CNC machining equipment. Is a price-performance required in factories, mines, scientific research, medical and other fields, ideal AC voltage equipment. How it works: The Series AC power supply by the control circuit and servo motor and other components. Control when the input voltage or load voltage changing circuit to change sampling, comparing, amplification, and then controls the servo motor operation, so that the position of the regulator to change the brush, thereby maintaining a constant output voltage. Because it is geared servo motors and brush between, and therefore drive more precise, the output voltage can be maintained very high accuracy. This product 3KVA the following specifications for self-coupling type, there are two kinds of 110V and 220V output. Single-phase 5KVA, three-phase 15KVA above specifications are compensated. Compensation circuit and compensation by the regulator transformers and other components. Three-phase 30KVA following product specifications (TNS / SVC series) are used to adjust the structure independent phase, which is characterized by the power grid can effectively eliminate or phase unbalanced load impact on electrical equipment. China Powerware Electric (Group) Co., Ltd. Note: This product is bulky items, all take the logistics, logistics costs charged by actual, please customers must communicate well in advance before ordering the freight, shipping does not prevail over the edge, thank you patronize the company. If the problem can inquire, Buyer Tips: Hello Dear Customer, Please read the following carefully before I buy store merchandise: 1, [promise] this shop for Chinese Powerware Electric (Group) Co., Ltd.'s? Net sales Station - the products are sold factory direct original authentic products, Our purpose is: the same product than the quality, the same quality than price, the same price than service! Please reassure parents to buy used. 2. [proposed] purchase regulators suggest that you at least have to buy more than three times larger than the actual power of the regulator, as many starts instantly generated when electrical power is large (such as: CNC machine tools, medical equipment, machinery equipment, refrigerators, air conditioners, electric stove, washing machine, motors, pumps, compressors and motors, etc.), typically about 3-5 times the rated power, so that those equipped with motors, compressors and other inductive electrical load regulator devices must consider its power reserves to allow sufficient margin to avoid the impact of current when the load boot cause immediate damage to the regulator. 3, [delivery] product before delivery after repeated test machine, after strict inspection before packing shipments, to ensure there is no quality problem! But because the regulator is a special product, there may still be functional vibrations generated during transport due to defect, quality problems are difficult to determine because of what causes. So please notify us within 24 hours of receipt, we offer the same model replacement services. Buyer is responsible for the safe transportation of goods shop, the shop is responsible for return shipping costs. 4, [acceptance] buyers must first inspection before you sign, if the appearance of damaged or missing items, please reject, once losses as buyers negligence, pro shop you can not afford the loss of hope and understanding! ! ! 5, [OK] buyer within three days after receipt of goods to detect and confirm the arrival of goods, the arrival to the courier company website based on the time of receipt, the arrival of buyers expired unconfirmed, sellers will depend on its waiver commodity service. 6, [returned] Please choose the right model when buying, to consider the future business expansion, whether the need for additional equipment, expand the capacity of the regulator needs to be reserved. If it is not because of quality problems need to replace other types of models, you must bear the return postage! . 7, [sale] Service: Powerware Electrical year warranty! ! ! Maintenance for life! ! ! a, shop sold goods are in accordance with the time specified by the manufacturer warranty (counting from the time of purchase). b, merchandise during the warranty period, if you return the Powerware service quality problems under normal use of non-human, postage paid by the company! (This service is service, which returned it returned). c, the warranty period of commodities, and if repairs need to pay the maintenance costs. d, in the question above refers to commodities commodity hardware problem. 8, [bless] I wish you a happy shopping!
