產品簡述 (Product Profile)
DBU系列制動單元的作用是將馬達在減速的過程中產生的再生能量，以熱能的形式消耗在制動電阻上，從而改善變頻器的制動性能及縮短變頻器的制動時間。The function of the DBU braking unit is to divert into a braking resistor the regenerative
energy produced in the process of decelerating the motor, converting that energy into heat.Regenerative energy flows from the motor into the inverter DC Bus, manifested as increased bus voltage. The advantage gained using the DBU is improved braking performance and shorter deceleration time of the load.
產品特點 （Product Features）
1、安全性：具有IGBT短路擊穿脫扣功能，可以有效地防止
因 IGBT擊穿，電阻器長時間過負荷運行而引起的火險
隱患。
2、廣泛性：特殊設計可以使用普通電阻，不必選擇無感電阻。
斬波電壓DC630V-DC760V可調，適用于各種中低壓變頻器
（特殊設計可達1200V）。
3、經濟性：性價比高，品質可與同類進口產品相媲美，價格較
低，是變頻器剎車、制動回路中經濟、實用的配套產品。
4、可并聯使用：采用書本型設計，可無間隙并聯安裝，推薦最
多3臺并聯使用。
1. SAFETY: the tripping function against IGBT short circuit breakdown can avoid the
fire caused by IGBT short circuit breakdown of resister after overload run.
2. WIDE COMPATIBILITY: It’s special design makes it compatible with
general resistance rather than non-inductive resistance. It’s adjustable chopper
voltage DC630V-DC760V is applicable to various low-voltage inverters.
3. ECONOMICAL FEATURE: It has a very high ratio of performance to price and it’s
quality is parallel to similar type of imported product.yet has a lower price. It is
considered the most cost-effective and practical auxiliary product for braking
circuits ofinverters.
4. ADAPATABLE to CONNECTIONS in PARALLEL: It adopts a book-shape design
and can be installed in parallel connection with zero clearance. It is recommended
that up to 3 units can be connected in parallel.
