Product Description
14V Alternator Controller Unit (ACU), Voltage Regulator with Field to Ground Short Warning
What’s included:
- Installation Drawing
- Warranty Card
- Product Eligibility Catalog (PEC)
- Troubleshooting Notes
- Instructions For Continued Airworthiness Maintenance (ICA)
Product Features:
Voltage Regulation, Pulse Width Modulated
The Voltage Regulator with Pulse Width Modulated (PWM) field control keeps the bus voltage constant by controlling the alternator’s field current: increasing it when the system load increases and decreasing it when the load drops.
Field-to-Ground Fault Protection (GFP)
If the alternator’s field shorts to ground, the field-to-ground short protector will deactivate the Voltage Regulator, and switch on the unit’s Red field-to-ground short Red TSL.
Trouble-Shooting Light (TSL)
The TSL (on the unit) is designed to alert the user to the condition of the Alternator / ACU system.
Other Features:
- Increased Regulator life
- Reduced panel lights flicker
- Protects against grounded alternator field
- Identifies grounded field
- Reduced trouble-shooting time
