Frequency inverter in modular design

BMR elektrischer und elektronischer Gerätebau launches the compact SFU 1000 frequency inverter in modular design for the control cabinet with a continuous output power of 1000 VA.

The SFU 1000 frequency inverter from BMR

In order to be able to drive larger spindles with higher current requirements at 55 V(AC) output voltage, the permissible output current has been increased to 12 A. BMR has extended the I/Os for flexible integration into the customer's specific application: Four freely parameterizable inputs and outputs are available as plug-in screw terminals for conductor cross-sections of up to 1.5 ^mm2. Three output channels are implemented as active outputs with 0 to 24 V levels and can therefore directly control PLC inputs. Another output is designed as a relay with changeover contacts for switching potential-free signals. The frequency inverter meets all requirements for 'Safe Torque Off' with the 'Safe Torque Off' (STO) function. The STO function prevents a spindle from starting up unintentionally when the machine is at a standstill during service work.
