89 制动单元 Braking Unit DBU系列制动单元的作用是将马达在减速的过程中产生的再生能量,以热能 的形式消耗在制动电阻上,从而改善变频器的制动性能及缩短变频器的制动时间. 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. 1.Safety: The tripping function against IGBT short circuit breakdown can avoid the fire caused by IGBT short circuit breakdown of resister after long-time overload run. 2.Wide Compatibility: Its special design makes it compatible with general resistors rather than non-inductive ones.Its adjustable chopper voltage DC630V-DC760V is applicable to various low-voltage inverters. 3.Economical Feature: Its cost performance is high.Its quality is parallel to similar type of imported products but its price is low.It is considered the most cost-effective and practical auxiliary product for braking circuits of inverters. 4.Adaptable to connections in parallel: The book-shape design is adopted and Braking Units can be installed in parallel connection with zero clearance. It is recommended that up to

3 units be connected in parallel.

1、安全性:具有IGBT短路击穿脱扣功能,可以有效地防止 因IGBT击穿,电阻器长时间过负荷运行而引起的火险 隐患.

2、广泛性:特殊设计可以使用普通电阻,不必选择无感电阻. 斩波电压DC630V-DC760V可调,适用于各种中低压变频器 (特殊设计可达1200V).

3、经济性:性价比高,品质可与同类进口产品相媲美,价格较 低,是变频器刹车、制动回路中经济、实用的配套产品.

4、可并联使用:采用书本型设计,可无间隙并联安装,推荐最 多3台并联使用. 产品简述 (Product Profile) 产品特点 (Product Features) 产品尺寸图 (Product Size) Picture A 图APicture B 图B254
