ESD5221 Electronic Speed Control Generator Governor


ESD5221 Electronic Speed Control Description

The ESD series governor is precise speed controls designed and manufactured in various configurations to meet application requirements using the latest analog and digital control technologies.
 - A wide variety of application needs can be satisfied with  ESD series constant or variable speed governing, in isochronous or droop operation.

1) The ESD5221 Series speed control unit is a fully electronic device designed to control the engine speed by responding quickly and accurately to transient load changes.
2) Synchronous operation / stable ----- +/- 0.25% or higher
3) Power supply-12 or 24 VDC battery system (transient and reverse voltage protection)
4) Power consumption-50 mA continuous plus actuator current
5) Maximum actuator current at 25ºC (77ºF)-continuous -10 amps
6) Weight: 0.77 kg
