What’s included:
- Installation Drawing
- Warranty Card
- Product Eligibility Catalog (PEC)
- Troubleshooting Notes
- STC Certificate
- Instructions For Continued Airworthiness Maintenance (ICA)
Product Features:
Voltage Regulation, Remote Voltage Sensed
The Controller or Voltage Regulator, with Remote Voltage sense of the Alternator output, keeps the bus voltage constant by controlling the field current: increasing it when the system load increases and decreasing it when the load drops.
Low Voltage Warning Light Output1
A warning light connected between pin I and the bus comes on to warn the pilot if the bus voltage exceeds the OV level or the alternator is off-line due to Field-to-Ground Fault Protection (GFP).
Field-to-Ground Fault Protection (GFP)
An alternator field-to-ground short will cause the field-to-ground short protector to deactivate the Controller and switch on the unit’s Red TSL, and the LV-OV indicator on the instrument panel.
Trouble-Shooting Light (TSL)
The TSL (on the unit) is designed to alert the user to the condition of the Alternator / Controller (ACU) system.
Additional Features:
- Increased Regulator life
- Reduced panel lights flicker
- Warns the Pilot of Low & OV Conditions
- Protects against grounded alternator field
- Identifies grounded field. Reduce trouble-shooting time.
