Computer compatible.
Solid state electronics.
Compact design.
±0.5% position accuracy.
Rapid response time.
Wiring leads are fully encapsulated.
NIKKISO Hydroflo’s Electronic Capacity Control (ECCA) permits the automatic adjustment of pump
capacity. Replacing the standard manual micrometer knob and mounting directly on the pump,
the ECCA uses miniaturized, state-of-the-art electronic technology built around an
AC synchronous motor. This permits precise actuator travel, without hunting or overshoot.
All ECCA units are supplied with color-coded wiring leads which simplify field installation,
and are fully encapsulated to keep moisture out. The encapsulated wiring leads also eliminate
the need to open actuator housing to accomplish field wiring.
