Description
MITSUBISHI ELECTRIC FR-BU2 — Inverter Option Brake Unit FR-BU2 Series, genuine MITSUBISHI ELECTRIC product.
Overview
The MITSUBISHI ELECTRIC FR-BU2 Series brake unit is an inverter option that switches regenerative energy into an external resistor when the DC bus voltage rises during deceleration. This enables faster stopping and continuous braking beyond the inverter's built-in capability. It is used with matching resistors for high-inertia loads, hoists and frequent-stop applications.
Key Features
- External braking for inverter drives
- Used with dedicated brake resistors
- Selected by capacity and voltage class
