ASP-96

STABLE & SPEEDY CONTROL OF GENERATOR POWER FACTOR
ASP-96■ APPLICATIONThis product controls power factor of synchronous
generator constantly in parallel operation with system.
Power factor of generator can be improved by constant
power factor even though load fluctuated.

■ FEATURES► Space saving is achieved with light-weight, small-size.
Mounting area is reduced to approx. 1/6 compared with our conventional product (ASP-101).

► Easy to see display and simple setting.
Power factor control state and power factor current value can be easily displayed by panel
mounting. Setting value can be changed easily from front with cover being open.

► Hunting prevention of control
Hunting is prevented and control is performed quickly as pulse width is automatically set bydeviation.

■ FUNCTION► Remote operation (REMOTE) of control power factor
Power factor setting value can be changed from distance by analog signal in proportion
to power factor setting value. Analog signal is equivalent to LEAD 0.9-1-LAG0.7/ DC10.4-12-16.8mA.

► Neutral zone automatic changeover
Neutral zone can be changed over by generator load power in order to make a stable control.
Also control can be stopped when power is small.

► Pulse output deviation control
Pulse width of control output pulse can be controlled by phase difference of setting value and current
value to make a speedy control.

ASP-96► Voltage control system failure detection function
When voltage control signal (60R, L) outputs in the same direction for 60 times continuously, but it
does not reach to the aimed power facto value, ALARM outputs for voltage control system abnormality.
