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.
Perfect for cranes, conveyors, machine tools, pumps, and other high-cycling equipment. The HH-02105 enhances system stability, minimizes mechanical wear, reduces downtime, and extends the operational life of your entire motor drive system.
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.
