Information About APR63-5
The APR63-5 is an excitation controller housed in an epoxy-potted plastic case. Its single-phase sensing circuit uses selectable 240 V and 480 V taps to accommodate different generator voltage configurations. The regulator compares sensed voltage with an internal reference and adjusts excitation in response to deviations. Internal voltage adjustment and an optional external potentiometer support setup for compatible generator systems.
Key Features:
- Automatic Voltage Regulation: Adjusts exciter field power in response to changes in generator output voltage.
- Selectable Sensing Taps: Supports nominal 240 V and 480 V generator sensing configurations.
- Continuous Field Output: Supplies up to 5 A DC at 63 V DC for continuous excitation.
- Forcing Capability: Provides up to 8.5 A DC at 105 V DC for one minute.
- Residual Voltage Buildup: Builds generator voltage automatically from residual voltage as low as 6 V AC.
- Voltage Adjustment: Includes internal adjustment and supports an optional external potentiometer.
- Overexcitation Shutdown: Removes field power when excessive field voltage meets the shutdown criteria.
- Encapsulated Construction: Uses an epoxy-potted plastic enclosure for generator-mounted applications.
The APR63-5 delivers the reliability and precision required for brushless generator voltage regulation and excitation control.
