The R15100 Rev A is a 14Vdc solid state Alternator Controller (Voltage Regulator) designed for use with 12Vdc aircraft alternators. This unit provides Voltage Regulation, Field induction protection, Low/High Voltage indicator pin, and self-protecting Field-to-ground short protection, as well as an on-unit Field Fault/Function indicator. The indicator pins allows a light connected to it and bus to come on whenever the alternator switch is open, the OV sensor is defective (open), or the wire to pin S is open. The unit will turn itself off and turn on a RED light if it senses that the alternator field or field wire is shorted to ground. When the ground fault is removed or repaired, the unit with come back on line (with a GREEN light) once the alternator switch is cycled. If the wire from the alternator battery terminal to pin A is broken, the on-unit light will be OFF. The R15100 Rev A has two mounting holes and fully pin and function compatible with the Cessna equivalent unit.
Voltage Regulation: 14.2V + 0.2V. Max Field Current: 5A.
|The R15V00 Rev A replaces: |
• CESSNA P/N: C611001-0201, -0101, -0102
• BEECH P/N 33-380010
• ELECTRODELTA P/N VR 600
• PFT/LAMAR P/N: DGR 6
• FORD P/N: D4FF-10316-BA, CA.
This unit is a direct replacement of the OEM Voltage regulator for most Cessnas listed. Its has no Overvoltage Circuit built in and relies on the original Cessna Over Voltage Sense unit PN C593001-0101 installed between the Alternator Switch and Alternator Field Circuit breaker to trip the regulator circuit inside the ACU (Alternator Control Unit) from the factory. Just bolt it on the Firewall and go. No wiring changes needed. But most of those Overvoltage parts are pushing 40-50 Years old. Spend the extra money and buy the Zeftronics R15V00 which includes the Over Voltage Sense in the ACU. The old Cessna Over Voltage Sense unit PN C593001-0101 will need to be removed though. Some minor wiring work will be needed. Check out Zeftronics Web site for more info.
Great Regulator. Lasts for years.
Removed old Regulator and mounted this replacement in about 3 minutes. Worked great. Fast shipping. Very please.
The part arrived on the date promised and the shipment was complete. I provided the component to my mechanic who has not installed it yet. Will update the post if there is anything remarkable after the install.
I should have known better than to order this regulator for my GENERATOR, standard-equipped Cessna 150C. However, my mechanic recommended it and the catalog lists this early model 150 as applicable. The mistaken assumption is the airplane has been converted to alternator. This resulted in an unnecessary return and restocking cost. Please make a cautionary note in your catalog.
The voltage regulator seems to work OK, but Zeftronics technical support is non-existent. Called several time, left messages and phone #, but no response.
Per the supplier: R15100 Rev A is FAA-STC, requiring the filing of FAA Form 337. No, the R15100 Rev A is not field adjustable. We have added a link to the Zeftronics warranty terms in the "Documents" tab of this web page.
This does not have built in over voltage protection. You would want R15V00 Rev A, it has the over voltage protection.
