HLT05.1W-045K-N-D7-NNNN

The HLT05.1W-045K-N-D7-NNNN, Bosch Rexroth Indramat, HLT Braking Units module safeguards drive systems by regulating the DC bus and absorbing regeneration energy. It supplies consistent overvoltage protection and resists shock and vibration for demanding industrial applications. Designed for direct front-mounting, the unit features simple tool-free installation and robust galvanic insulation to isolate downstream electronics. Its compact footprint and lightweight housing streamline integration into existing automation cabinets without compromising performance.

In operation, the brake chopper accepts a DC bus voltage of 750 V DC and continuously dissipates 45 kW of braking energy through an efficient Air Cooling system, while maintaining a minimal power loss of 250 W. During peak deceleration, it channels up to 85 kW into its resistor network within a 60 s cycle without thermal derating. The assembly is rated to IP 00 for interior cabinet use and weighs just 7.5 kg, ensuring a high power-to-weight ratio. It performs reliably up to an ambient operating temperature of 40 °C, can be stored from –25 … +70 °C, and withstands elevation up to 3000 m above sea level.

Seamless plug-and-play integration with Bosch Rexroth servo drives accelerates commissioning and reduces engineering overhead. Built to EN 50178 standards with full galvanic isolation, the unit delivers exceptional reliability and minimized downtime in harsh environments. Backed by a one-year warranty and global support, the HLT05.1W-045K-N-D7-NNNN is ideal for automotive production lines, material handling systems, and packaging machinery requiring precise braking control and energy management.
