Essential details:8272-517 controller module
Product Description
The 8272-517 is a controller module manufactured by Woodward. Here are some key information about the product:
Brand: Woodward
Model: 8272-517
Country of origin: USA
Weight: 0.95kg
The controller module has the following technical description:
It is used with engines equipped with speed control and accepts ±3 Vdc speed setting inputs, 0.5 to 4.5 Vdc inputs, or PWM(pulse width modulation) inputs.
The load sharing module allows the use of Woodward power generation accessories and allows load sharing between engines equipped with speed controls not manufactured by Woodward.
Modules provide synchronous and droop load sharing capabilities for engines in generator set applications.
Additional devices in the control system can include Woodward SPM-A synchronizers, SPM-D synchronizers, automatic generator Load Control (AGLC), and Automatic Power Transmission and Load Control (APTL).
Power supply DC model 18-32VDC, about 5w. Ac model jumpers can be selected from 95-130 or 190-260 Vac wire-to-wire, 50-400Hz, about 10w.
Inputs include three-phase PT input and three-phase CT input, load sharing input 0-3 Vdc to 25 kΩ impedance in isochronic mode, open circuit in droop mode.
The sync input is compatible with the optional Woodward SPM-A synchronizer.
Allows manual adjustment of output level with external 10 kΩ potentiometer.
Droop switch The external droop switch is connected to the auxiliary circuit breaker contact in series.
The output load signal is a DC signal proportional to the total actual current detected by the load sharing module.
Output speed control +0.5 to +4.5 Vdc analog, ±3 Vdc analog, or PWM, depending on model.
