COVID-19 - update

The health and well-being of our employees, customers and suppliers are of paramount importance to us.

We continue to monitor the latest advice and guidance from the government and are working on measures across our business to minimise any future disruption which we may experience.

Motortronics has been deemed part of the “essential” business supply chain due to the industries and customers we serve.

We have a carefully restructured operation in place to ensure continuity of service and supply and will continue to ensure that we are following latest government & health guidelines to support the health and welfare of our staff worldwide.

Our staff are available via phone, email or video conference facilities in lieu of face to face meetings.

We are continuing to monitor the situation and should anything change a member of our team will be in touch directly. For more information click here for a statement from Motortronics’ Vice President – Joyce Mitchell.

Control of resistive and lamp type loads

Motortronics’ EZ Series are true zero voltage switching controllers. They are designed to fire at the minimum voltage differential across the SCR with a gate pulse applied prior to the zero-crossing point. These controllers are virtually RFI free.

The EZ Series zero fired (Variable time base) SCR Power Controllers combine low cost with microprocessor technology. They feature a rapid-cycle control technique that provides resolution that potentially extends the life of industrial resistance heaters. This variable time base control technique minimizes off time and is characterized by rapid on/off cycling with on-to-on cycle time ranging from 1 to 3 cycles for power ranges of 25% to 100%.

Thermal cycling of the heater elements is reduced to a minimum for all power levels to improve element life. Control of the on-to-on cycle times provides the resolution required to maintain a smooth, even output from resistance heaters.

The number of on cycles within a burst and the off time between bursts is continually monitored and updated by the microprocessor. A constant heater output is ensured since the unit’s output will continuously change to satisfy load requirements.
