Thunderpower TP610C Safety Recall
 
Thunderpower TP610C Safety Recall
I stumbled upon this in the Hacker website:

http://www.hacker-motor.com/produktr...part-29763804/

and the tonisport site:

http://www.fast-webshop.com/tonisport/0/0/2/10

It is dated 2014/04/04 in the Hacker site.

There is insufficient isolation between the primary and secondary windings in the internal power transformer of the unit.

I don't know if this applies to US units with 110v input.

Standard factory testing involves hypot testing way over rated voltage: I think this is what is involved here.

it might be testing at 3000 volts between primary and secondary windings.

Yes, the article mentioned it failed a 3kV punch through test.

It did recommend that the charger not be used and returned for repair.

Well, that's like a 10 year old recall? So unless you have an old one... I have a TP-610C but it's 12v only. I don't see a manufacturing date anywhere on it, so I wonder if the ones that can plug into the house outlet would. Also, I wonder if it's just the 220v ones as the sghts appear German, or includes 110v?

The USA UL standards for electric motors indicates hipot testing consisting of 1000 Volts AC plus double the AC rated voltage. So, a 120 VAC unit would need to withstand 1000 plus 2X120 or 1240 VAC.

Hipot testers can be a bit pricey.

Take a look:

Before retiring, the company I worked for routinely hipot tested every high voltage circuit breaker at voltages up to 85KV, checking both bushings to ground, and, 85KV directly across the circuit breakers open contacts.

The shop had to be careful. Applying 85KV AC voltage hypot tests across an open vacuum type circuit breaker contacts generates soft X-Rays. Lead shields were required.

Hi,

I just saw the article there when I was looking at their motors, so I thought it may be useful to someone.

Cheers
