Invertek has launched a PCB-based variable speed drive for applications
normally considered too arduous for conventionally constructed and housed
drives. The Compact Optidrive uses a stainless steel plate on which the
electrical connections and laser trimmed resistors are directly printed.
The remaining electronic components are also mounted on this plate. Its
inherent low profile ensures a high vibration rating, which coupled with
the strength of the steel plate and the fact that the entire electronic
circuit can be sealed, ensures a high overall environmental rating for
the product.
