Features and benefits

Suitable for fast rotating fields up to 600 Hz

Conversion of the PWM output signal (symmetrical

voltage components) of motor drives into a smooth

sine wave with low residual ripple

Elimination of premature motor damage caused by

high dv/dt, overvoltages, motor overheating and

eddy current losses

Significantly increased service life of expensive

(high-speed) motors

Reduction of the pulse load of motor drive IGBTs

and the parasitic losses on long shielded motor

cables

Less interference propagation towards neighboring

equipment or lines

Advanced choke design to minimize filter losses

and voltage drop

IP 20 protection, touch-safe terminals and

temperature monitoring function to increase overall

equipment safety

Typical applications

Motor drives and motors in high-speed applications,

like:

High-speed spindles

Textile machinery

Lasers

Military appliances (400 Hz)

Motor drive applications with medium to long motor

cables and/or with multiple motors in parallel, like:

Pumps

Conveyors

* General purpose four-pole (1500 r/min) AC induction motor rated 480 V/50 Hz.

** Exact value highly depends upon the motor cable type and length, switching frequency, motor frequency and further stray parameters within the system. Please contact your

local Schaffner partner for individual application support.

Typical block schematic

Temperature monitoring function

All filters of this range are equipped with a temperature monitoring function. The built- in temperature sensor opens a potential-free contact in the case of filter

overtemperature (>120ºC). The maximum switching capability is 6 A/250 V. This function can be used, for example, in the input of a CNC controller or as the trip of a

circuit breaker in order to interrupt the mains power supply. Connections are located next to the phase connectors (see mechanical data for details).

Forced cooling

The 75 A and 120 A filters provide internal cooling fans which require external power supply (24 VDC/~4 W). Connections are located next to the connectors of the

temperature sensor (see mechanical data for details).

For additional information please consult the Schaffner application note „Sinus Plus − New Output Filter Concept for Power Drive Systems“.
