AC32 Tech Notes

Commutator does not charge properly

TN0918

Product: AC32, AC64
Version: AC32 < 5000, AC64 < 3000
Date Added: 2013-04-16

Issue

Commutator charge life drops significantly, or device no longer charges.

Solution

Commutators and battery-powered amplifiers use the same 6V center pin negative charger. Affected commutators have a deeper power socket, which the normal charger won't reach; they use a charger with a modified extended barrel. Verify you are using the correct charger before contacting TDT for support.

Commutator motor fails on startup

TN0212

Product: AC32
Version: < 2000
Date Added: 2006-09-11

Issue

Because the voltage supplied to the commutator motor was marginal for initial startup, some commutators could fail to move on startup.

Workaround

The motor drive circuit has been redesigned to ensure ~4.0V supplied to motor. (ECN 6601)

Solution

If you experience this problem, contact TDT for an RMA to upgrade your current module.
