THE Sprecher + Schuh advanced control system (ACS) from NHP is an established group of coordinated components that can be used individually as stand-alone devices or, collectively, to form part of a total motor control package.

Through recent releases, the ACS now comprises CA 7 contactors, CS 7 relays, KT 7 circuit breakers, CT 7, CEP 7 & CEP 7C motor overload relays, the KA busbar system and the PCS and PDS soft starter products.

The Sprecher + Schuh PCS & PDS soft starters offer control of all three phases to the motor, electronic motor overload protection with adjustable trip class and selectable 'automatic or manual' reset functionality, together with several other motor and system protection functions more commonly expected from 'high end' soft starter products.

The PCS is suitable for motor starting applications to 18.5kW @ 400V ac and is intended for 3-wire motor connection.

It provides the user a selection of starting and stopping modes, thus enabling optimum control to be achieved in the vast majority of industrial applications.

The PDS is an advanced star/delta starter replacer currently available to 30kW @ 400V ac. It is intended for 6-wire motor connection and offers current limit starting as standard.

Both product lines will be further expanded in the near future to accommodate higher capacity industrial applications.

Installed system cost is greatly reduced through the compact dimensions and the 'plug and play' nature of the PCS & PDS products.

Connection links to CA 7 contactor and KT 7 breakers are readily available, as are optional auxiliary contacts, remote reset solenoids, cooling fans for high cyclic operation and marking tags for clear labeling of system components.
