In house test equipment

[codymiller]

Hi all,
 
I have a question regarding Taiwan regulatory requirements. We have some in
house custom bench top test equipment we have designed and use in our company.
We would like to send a couple units to our plant in Taiwan. Do I need to have
the equipment tested to meet Taiwan regulator standards. We do not sell this
item and we at most will ship a couple units into our Taiwan facility.
 
Thanks,
Cody

Re: Cigarette socket in vehicles

[Doug Smith]

Hi Ed and the group,

In addition to the 12/14 Volt question there are a few other points to
consider.

1) pretty big fast transients from loads like the starter motor

2) load dump conditions (battery becomes disconnected when engine is running)
where the alternator drives the voltage way above the normal ~14 Volts for a
time. This is more common that you might think, these days caused by lead-free
battery clamps failing. (Lead free battery clamps strikes me as a very bad
idea and does not accomplish anything compared to the battery itself and the
real source of lead from cars, the wheel weights flinging off wheels.) I have
observed first hand one of these clamps failing during use and immediately
replaced both clamps with nice lead ones.

Automotive electronics are designed to withstand load dump conditions but your
electronics may not be.

Hello Scott, 

In the case of 12V accessories to plug in normally they have a 
regulator
installed to prevent the overvoltage. 

Thank you.

Initial assumptions can be deceiving. I recently bought a Magellan GPS. 
It
operates on 5 VDC, and came equipped with an external "cigarette socket"
adapter. I assumed the cheapest, that there was a little resistor inside the
adapter, or just possibly a cheap linear regulator. On taking the adapter
apart (yes, I tend to do things like that), I was quite surprised to find a
little 2 custom IC switching converter, with input inductors, filter
capacitors and a hefty input overvoltage clamp.
 
The input voltage range was not specified, but it seems likely to be 
capable
of 24 VDC operation.

UL 60601-1 Medical Standard

[Robert F. Keller]

Hello Group,

Our lab is evaluating a medical device to UL 60601-1, General 
Requirements for Safety.  The Patient Axillary Current Current exceeds 
the limits specified in Table IV.  We are now thinking that under the  
60601-2 amended standards for medical devices, that there are changes to 
the leakage current limits depending on the device such as a 
defibrillator or a electrocardiograph.  Any ideas you have would be 
greatly appreciated.

I have learnt that cigarette sockets supply two voltages: 12 or 24 volts.
12-volt sockets are widely used in light duly vehicles while 24-volt
sockets in heavy duty vehicles.  The sockets are identical in terms of
configuration and dimensions.  Is there any mechanism to prevent a 12-volt
equipment from being plugged in a 24-volt socket?

RE: Cigarette socket in vehicles

[Scott Xe]

It sounds the users are not really aware of 12 or 24 Vdc on the cigarette
socket.  They just used it by experience.  Some better equipment are built to
work on both voltages to help the users.  Are those sockets always marked with
output voltage and current like other electronics equipments?

Cars are designed by mechanical engineers. They move very slowly when 
dealing with 'electricity'.(;-)

Yes, the present version of the connector is pretty unsatisfactory. The 
old type, that only had a real 'cigar lighter' to plug into it, was more 
reliable; it had to be, the current was about 10 A, and a bad contact 
would fry the lighter.

RE: Cigarette socket in vehicles

[James, Chris]

Perhaps because the cigarette lighter came before electronic gadgets in
vehicles and when gadgets did start to come to market they had to use what was
available with the result that the whole after-market gadget industry is
subsequently geared up to use the lighter socket as a power source

By the way.

I don't understand why cars still don't have specialised sockets for
electronic equipment.

The cigarette sockets likes to lose contact (it is my experience).

Subject: Cigarette socket in vehicles

 

I have learnt that cigarette sockets supply two voltages: 12 or 24 
volts. 
12-volt sockets are widely used in light duly vehicles while 24-volt sockets
in heavy duty vehicles.  The sockets are identical in terms of configuration
and dimensions.  Is there any mechanism to prevent a 12-volt equipment from
being plugged in a 24-volt socket?

 

Thanks,

Hello Scott, 

In the case of 12V accessories to plug in normally they have a regulator
installed to prevent the overvoltage. 

Thank you.

Initial assumptions can be deceiving. I recently bought a Magellan GPS. It
operates on 5 VDC, and came equipped with an external "cigarette socket"
adapter. I assumed the cheapest, that there was a little resistor inside the
adapter, or just possibly a cheap linear regulator. On taking the adapter
apart (yes, I tend to do things like that), I was quite surprised to find a
little 2 custom IC switching converter, with input inductors, filter
capacitors and a hefty input overvoltage clamp.
 
The input voltage range was not specified, but it seems likely to be capable
of 24 VDC operation.

Adaptors for the likes of mobile phones etc (needing 3 – 6V dc) I would
imagine are designed to work from 12V – if plugged into 24v I expect the
dissipation would be too great. That why there are after market 24V dc to 12V
dc adaptors available:

RE: First EUP Regulation implementation regarding standby power

[Barker, Neil]

Scott,

That is correct. EU Directives require transposition into the legislation of
the Member States, but EU Regulations have legal effect in their own rights.
Regulations are usually used to add detail to legislation that has already
been implemented in national law.
