ETA-ECM30
30A AC Power Module Spike Suppressor
INTRODUCTION
Thank you for purchasing the ETA Systems ETA-ECM30 AC Power Module Spike Suppressor Unit. Note: For your safety, all electrical wiring should be done by a qualified electrician.
The ETA Systems ETA-ECM30 is an Electrical Control Module (ECM) 30A AC Spike Suppressor that is designed to be used as a stand-alone unit or in conjunction with an ETA-ECS6RM Controller up to 1000ft away. AC Spikes, or transients, are commonly caused by utility power plant grid switchovers. The amount of energy that can be injected into the power system can be immense with voltages reaching 6kV or current peaks of 3000A. These spikes are very fast and usually only last for a very short period of time. To protect against this potential problem, incoming AC Mains have special suppression circuitry to eliminate the unwanted energy. The ETA-ECM30 circuitry is very fast and can suppress unwanted energy within a nanosecond, while sustaining the suppression for up to 2 milliseconds, thus ensuring virtually trouble-free protection.
High and low AC Main line voltages are another major contributor to equipment failures. The ECM modules support Extreme Voltage Shutdown (EVS) circuitry when used with an ETA-ECS6RM controller, which enables the module to be shut Off during high and low AC line conditions. High line voltages or surges usually are a slower steady state rise in voltages ranging from 128VAC and up. They can be caused by fluctuations in the utility company’s power lines or by industrial equipment turning On and Off when it is on the same power leg of the building’s incoming AC. Low line voltages or brownouts occur when the AC Mains drops below 107VAC. Most of the time it is caused by the utility company not being able to supply enough power during heavy utility consumption time periods, such as heat waves. Another factor can be from voltage drops in AC lines due to long transmissions. The ETA-ECS6RM will inform you if any of these conditions occur. Extreme variances in unstable AC Mains voltage are one of the main reasons for equipment failure.
