Electrical Housing for ETA-ECM20/ETA-ECM20M
INTERNAL ECM FEATURES OF THE ECM MODULES
Protection behind the Panel
• EMI/RFI Filters – ECM noise filtering for eliminating unwanted Radio Frequency Interference (RFI) that is commonly introduced
into the AC lines by nearby radio transmitters or wireless products. EMI filters are incorporated to reduce noise from
Electromagnetic Interference (EMI) from such items as electric motors, switching power supplies and lightning. The benefit of
these filters can be seen on video products or audibly by reducing static pops and external signal interference.
Note: Not available on ETA-20RW type module.
• AC Spike Protection - ECM modules feature AC spike suppression. AC Spikes, or Transients, are commonly caused by lightning
storms or 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 amperage 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. This circuitry is very fast and can suppress unwanted energy within a nanosecond, while sustaining the suppression up to
2 milliseconds, thus ensuring virtually trouble free protection.
• AC Surge Protection - High line can also be known as surges. Surges usually are a slower steady state rise in voltages ranging
from 128VAC and up. They can be caused from fluctuations from the utility company's power lines, or industrial equipment turning
On and Off, and are on the same power leg of the building's incoming AC.
• EVS Protection – If an ECM Module is connected to the ETA-ECS6RM, the ETA-ECS6RM has built in intelligence that monitors
the AC lines from the ECM modules and will inform you of potentially damaging voltages. If the AC Mains voltage is between
128VAC and 132VCA or 107VAC and 101VAC the display will flash an error code indicating a potential fault has occurred and
you should check sensitive equipment. If an extreme voltage swing occurs above 128VAC or below 101VAC, the Extreme Voltage
Shutdown (EVS) protection circuit will automatically turn all remote ECM modules Off until the system is manually reset. The EVS
feature can be defeated if required via the ETA-ECS6RM EVS bypass switch. Note: Not available on ETA-20RW type module.
• Over Current Protection – In the case of excessive current draw at the ECM module. An internal Slow Blow fuse will open
protecting the devices plugged in to the ECM module. Note: This fuse must be changed by a qualified service technician.
