JTATEF1203-0LB SIEMENS Exclusive Mdexx dv/dt Filter with VPL Original Brand New

The SIEMENS JTATEF1203-0LB Mdexx dv/dt filter with integrated Voltage Peak Limiter (VPL) is a reliable solution engineered for use with SINAMICS G120 and G220 drive systems. Designed to handle voltages up to 690V and power ranges from 110 kW to 132 kW, as well as 400V systems with outputs of 55 kW to 75 kW, this filter ensures dependable motor protection and system stability. By limiting the voltage rise time (dv/dt) and suppressing harmful voltage peaks, the unit extends the service life of standard motors, allowing them to operate securely under demanding converter-driven conditions.

The JTATEF1203-0LB incorporates advanced filtering technology that reduces electrical stress at motor terminals. When applied correctly, it guarantees voltage peaks remain within international standards (IEC/TS 60034-17:2006), maintaining < 1350 V phase-to-phase and < 1100 V phase-to-ground under a nominal DC link voltage of 935 V. This enables operators to deploy standard motors with conventional insulation and without insulated bearings, eliminating the need for specialized motor designs.

Overview

As part of the dv/dt filter family, the model integrates a voltage peak limiter for additional reliability. This combination enhances performance and ensures compliance with critical requirements for converter-based motor systems. Compatibility with SINAMICS S120 blocksize drives begins at firmware version V4.7 SP10, while later SINAMICS Pool Software versions V4.7 SP10 and V5.1 SP1 or higher support integration with G120 and S120 applications, respectively.

Design

The filter’s functional design consists of two main components: a dv/dt reactor that reduces voltage slope and a voltage limiting network that absorbs and feeds excessive energy back to the DC link. This dual structure provides effective suppression of peak voltages and ensures stable, long-term motor operation in industrial environments. With its robust construction, the JTATEF1203-0LB represents a dependable investment for facilities requiring enhanced motor safety and optimized drive performance.
