·SBW / DBW Series Compensated Power Supply
Power supply is composed by the compensation circuit, the voltage detection circuit, servo motor control circuit and the slow transmission, protection circuits and other circuits. Voltage adjustment methods is non-segmental, voltage is linear buck, and output voltage is continuously adjustable. Wide voltage range, precision adjustable, high efficiency without additional distortion output waveform, it can adapt to all kinds of loads. Principles are similar to ZTY, but create larger, more technologically advanced, single-cabinet can be to 300KVA, many cabinet can be to 3000KVA,It is suitable for large production lines, central air conditioning or whole plant used.
SBW / DBW series non-contact A-type regulated power supply on the market today utilize a large number of brushless type mechanical upgrade power supply products, which use high-power relays for dynamic voltage regulator off, to stabilize voltage. It uses ring-type transformer, which greatly reduces the power supply of its own power. 5A-type regulated power supply has no machinery, no carbon brushes, brush-type machine its response is faster 100 times than machinery; three-phase sub-tone, and input low voltage can also be run at full load; 5A type regulated power supply is more suitable to device whose regulation accuracy requirement is not very high, capacity is not a great need (such as welding and small-scale production line, etc.).
SBW / DBW series non-contact IC B-regulated power supply has a number of a specific sequence control thyristor voltage zero off, to change the size and polarity compensation voltage is AC thyristor switch technology with the perfect combination. Using high-power thyristor (SCR) to control instead of mechanical and carbon brush regulator, all part of the adjustment phase, the compensation range is up to 50%,efficiency is more than 99%, which is energy-saving green products, and have all protection, It is very reliable, adaptable exceptionally strong. Extremely long service life, can run continuously without failure for more than 100,000 hours to achieve a long-term maintenance-free power supply.
Note that a contact line regulation accuracy is up to 1% -2%, response time is slow ,0.5-2S. A precision low-type regulator, up to 5% response rate up to less than 100ms.B regulator up to 2% accuracy, response time less than 40ms.
