HH-02105 Braking Resistor & Frequency Sensitive Rheostat for VFD Inverters

The HH-02105 is an integrated, high-performance component combining a braking resistor and frequency-sensitive rheostat, purpose-built to optimize control, protection, and efficiency for variable frequency drive (VFD) inverter systems across industrial automation.

• Reliably dissipates regenerative energy during motor deceleration
• Prevents dangerous overvoltage spikes on VFD's DC bus
• Safeguards IGBTs, capacitors, and sensitive drive electronics
• Frequency-sensitive rheostat provides smooth, stepless resistance adjustment
• Automatically increases impedance at high startup frequencies to limit inrush current
• Gradually reduces impedance as motor speed rises
• Ensures seamless motor startup and precise speed regulation
• Enables rapid, controlled braking for high-inertia loads

Built with a rugged, thermally efficient aluminum housing, the HH-02105 offers superior heat dissipation, vibration resistance, and long service life in harsh industrial environments. Its compact, modular structure simplifies installation—whether cabinet-mounted or externally fitted—with broad compatibility for most standard VFD inverters.

Backed by stable performance and low maintenance requirements, the HH-02105 is the essential upgrade for industrial VFD applications demanding reliable braking and smooth power control.
