LENZE ERBS027R01K2 - Regenerative Braking Resistor
This component is a standard external regenerative braking resistor from the LENZE ERB series, designed to dissipate excess energy generated during motor deceleration. It prevents DC bus overvoltage in variable frequency drives by converting regenerative electrical energy into heat, ensuring stable operation and protecting drive components in applications with high inertia or frequent braking cycles.
Technical Specifications:
- SERIES/FAMILY: ERB Standard Series
- COMPONENT TYPE: Regenerative Braking Resistor
- ELECTRICAL SPECS:
- RESISTANCE: 27 Ohms
- CONTINUOUS POWER DISSIPATION: 1 kW
- PEAK POWER DISSIPATION: Duty cycle dependent, significantly higher than continuous rating
- MECHANICAL/PHYSICAL:
- FORM FACTOR: Enclosed, finned aluminum housing for passive heat dissipation
- MOUNTING: Wall or cabinet mountable
- INTERFACE/CONTROL:
- CONNECTION: Terminal block for direct connection to drive DC bus terminals
- CONTROL: Passive resistive element, activated by drive's internal braking chopper
- ENVIRONMENTAL/MOUNTING:
- IP RATING: IP20 (typical for cabinet-mounted industrial resistors)
- COOLING METHOD: Natural convection
- MOUNTING STYLE: Vertical or horizontal orientation for optimal heat dissipation
- COMPATIBILITY/APPLICATION:
- COMPATIBILITY: Compatible with LENZE frequency inverters (e.g., i550, 8400, 9400 series) and other industrial drives featuring an integrated or external braking chopper
- APPLICATION: High-inertia loads, rapid deceleration cycles, lifting equipment, centrifuges, machine tools, conveyors, and applications requiring controlled energy dissipation to prevent DC bus overvoltage
