General Description
The Atlas Power ECM-20 is a 20A Power Conditioner and AC Spike 
Suppressor that is designed to be used as a standalone unit or in 
conjunction with an ECS unit up to 1000ft away. The ECM-20 features 
AC Spike and Surge Suppression, AC Mains Voltage monitoring, 
EVS circuitry, and Remote Activation. The ECM-20 is designed to be 
conveniently housed in the ECM-RACEWY6 for the addition of multiple 
outlets directly connected to the AC mains from the electrical panel.
The Atlas Power ECM-20M is a 20A Power Conditioner and AC Spike 
Suppressor that is designed to be used as a standalone unit or in 
conjunction with an ECS unit up to 1000ft away. The ECM-20M features 
AC Spike and Surge Suppression, AC Mains Voltage monitoring, EVS 
circuitry, and Remote Activation. In addition, the ECM-20M features 
noise filtering for removing unwanted Radio Frequency Interference 
(RFI) and EMI filters to reduce noise from Electromagnetic Interference 
(EMI) caused by items such as electric motors or switching power 
supplies. The ECM-20M is designed to be conveniently housed in the 
ECM-RACEWY6 for the addition of multiple outlets directly connected to 
the AC mains from the electrical panel.
