High power also means heat removal
Hitachi describes cooling the original E2 converter’s GTO devices and resistors separately from its control electronics. Equipment generation matters when comparing this train with E2-1000.

Technical profile
E2-1000 · ten-car specification published in 2013
The 50 Hz supply here applies to the 1000 subseries. The original E2-0 was developed for both 50 and 60 Hz sections, including the steep route towards Karuizawa.

Inside the engineering
Original E2 / Hitachi equipment · 1997; suspension facts separately identify E2-1000
| Bogie identification | DT206 · original E2 powered bogie 1 |
|---|---|
| Converter cooling | Forced-air main circuit; cyclone-filtered control compartment 1 |
| E2-1000 suspension allocation | Full active at both ends and the Green car; semi-active on other cars 2 |
| E2-1000 actuator medium | Compressed-air actuators counter sensor-detected lateral motion 2 |
Suspension was allocated by car
JR East describes a combination of active suspension and inter-car dampers. The full-active equipment was concentrated at the two ends and Green car, so it should not be described as an all-car system on E2-1000.
