Supplier News

AMPCONTROL’S range of products launched this month includes the IPM Integrated Protection Relay, ELM Earth Leakage Relay and ECM Earth Continuity Relay.

The range of products being launched this month includes the IPM Integrated Protection Relay, ELM Earth Leakage Relay and the ECM Earth Continuity Relay.

Tailored for metalliferrous application, the IPM is an intelligent microprocessor based relay that provides protection and control of electrical outlets supplying mining machinery.

The IPM combines a number of protection, recognition and alarm features into a single versatile relay.

The key features of the IPM relay include Earth Leakage and Earth Continuity in addition to the standard current and voltage monitoring functions.

A small remote termination unit enables machine recognition, this in turn allowing different size machines to be connected to the one outlet without the need to manually change any settings.

A MODBUS communication connection allows monitoring of the relays' measurements and state at any time through a two wire connection.

The system provides reliability by initiating pro-active and preventative maintenance programs and drive availability with pre-trip alarms on critical stand-by equipment.

Designed and manufactured in Australia, the ELM Earth Leakage Relay offers a range of market leading features.

With proven in-service performance, the relay incorporates all the safety features of Ampcontrol’s successful ELD Earth Leakage relay which is widely used in the Coal Mining Industry, but has been tailored to the metalliferrous market.

Enclosed in a small, high quality package, the ELM relay is a cost effective solution to ensure a level of safety and quality that was previously unknown to the metalliferrous market.The new relay provides a range of features benefiting the customer. It is electronic in design and is based on microprocessor technology for high stability and accuracy.

A definite time operating characteristic is provided with adjustable trip sensitivity and time delay.

Further extending Ampcontrol’s capabilities is the ECM Earth Continuity Relay which is designed to monitor the pilot earth continuity of trailing and reeling cables on an earth fault-limited system.

The Ampcontrol range is supported by extensive workshop and field service resources available to repair, service and maintain the equipment.
