SPECIFICATIONS AND TOLERANCES
WAVEFORMS 
Waveforms: 10/1000ms, 50-600V -0/+15% peak 
open-circuit voltage; 100A/side -0/+15% 
peak short-circuit current
10/1000ms, 50-1000V -0/+15% peak 
open-circuit voltage; 100A/side 0/+15% 
peak short-circuit current
10/1000ms, 50-1500V -0/+15% peak 
open-circuit voltage; 100A/side -0/+15% 
peak short-circuit current
Note:
All voltage and current specifications are 
minimum values, in accordance with 
Bellcore GR-1089-CORE.
Outputs are all true three-terminal outputs 
for testing either two or three-terminal 
devices or inputs. Outputs can be 
connected in parallel to double the 
available peak short-circuit current when 
testing two-terminal devices.
Front Time -30% /+0 for voltage;  
Tolerance: -40%/+0 for 1500V waveform and current
Duration  -0/+50% for voltage;  
Tolerance: -0/+20% for current
Surge 
Repetition 
Rate: 1 shot/40 seconds
AVAILABLE OPTIONS
E509A-S: Adds an oscilloscope trigger for 
any Surge network. 
E509A-VI: Provides monitoring of the peak surge
voltages and currents at the output of 
the E509 module. All measurements 
are logged by software for diagnostic 
evaluation or Go/No-Go testing.
Note: If an ECAT coupler/decoupler 
is included, waveform monitoring is 
available at the output of the 
coupler/decoupler without the 
addition of Option E509-VI. 
Model E509A
ECAT: AN EXTRAORDINARY CONCEPT IN EMC 
TESTING FOR VULNERABILITY TO SURGE, 
EFT AND POWER QUALITY.
ECAT is a totally integrated and modularized system
which offers unprecedented testing ease, accuracy and 
versatility to manufacturers, test houses, and anyone 
who will be testing for effects of Pulsed EMI.
ECAT is designed to test products according to a broad 
range of international standards developed by ANSI, 
the IEC, CENELEC and other agencies. The European 
Norms, developed by CENELEC, became mandatory 
on January 1, 1996 for all equipment shipped into the 
European Union or shipped across EU borders.
