NKU-MPPL-S6 is a universal transformer system with a switchable principle (philosophy) of lift control. The cabinet design implies two main elements: power and low-voltage.
The Transformer system implies a design change of the low voltage package depending on the conditions of its use (with a machine room, without a machine room, separate type) without changing the structural modules that make up the low voltage package. At the moment, three design options have been implemented: a mounted cabinet, a column cabinet and a split cabinet for distributing the power and control low-voltage parts.
The switchable control philosophy implies a quick change of the lift control philosophy (lift control matrix system and distributed system) in any of the 3 presented constructs by simply replacing two boards (interface board PGM and crossboard PPSh). At the same time, such a replacement can be performed directly under operating conditions.
The lift control system includes:
- The NKU-MPPL lift station — the main module of the system that performs the main lift control functions;
- Contactor control unit KUB — provides silent operation of the frequency device contactor group;
- Matrix crossboard — installed in the car, provides switching of the car devices with the lift station;
- Car panel board — used to connect control and display devices inside the lift car.
