产品简述 (Product Profile)
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.
产品特点 (Product Features)
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。
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.
