Hi all newbee here…

I am designing a machine for my customer for which we have to use mains to power cartridge heaters. However customer does not want a USA & eu machine.

Is there a module that will detect incoming Voltage either 110 or 220 ? As we can fit machine with both types of heaters & switch to use the appropriate ones depending on country.

Thanks

You could use a 220Vac coil relay with the NC contacts connecting the 110V heaters, and the NO contacts to the 220V heaters.
It would not energize for a 110V input, but would for 220V to connect the proper heaters.
(I assume the 220V heater could just be two 110V heaters in series.)

I assume you intend a M/C that will automatically connect. dependent on voltage?
I also assume you require the unit to be plugged into two or more separate style of socket? i.e. US & Eu etc?.
What could be done is make up a short cord/adaptor with the correct outlet plug for each systems, this cord would plug into a dedicated socket on the HTR , where the internal connections would be appropriate for the system used.

Wouldn’t a SMPS suitable for 110V to 240V suffice?.
Some voltage input range from 80V upto 240V.

Following up on crutschow's solution, there are two different configurations for a single-relay solution.

Start with one 240Vac relay with DPDT contacts.

1. The relay completely connects/disconnects two separate banks of heaters, one for 240 V and one for 120 V. To save a nickel, this can be done with a SPDT relay.

2. The relay configures one group of 120 V heaters for either 120 V operation (heaters in parallel) or 240 V operation (heaters in series).

It sounds as though the OP may want to adopt automatic detection.
Also needed is whether the machine is plugged in manually or is permanently wired at the installation.?

Welcome to Maker Pro! :) Yes there is...
How about a module called a automatic transfer switch it's good for Europe or United States. It will accommodate 50 or 60 HZ.

Seems a long way around ......... and costly as well.
One would expect any "machine" for a specific country would be supplied with the innards to suit that particular countries voltage/frequency.

Usually you'd use one set of heaters only, rated 115 V. Then use them in parallel in a 115 mains installation or in series in a 230 V installation. Saves a lot of money vs. 2 separate sets of heaters.

Sounds familiar ... wait ... Aha - post #5.

A simple multi pole relay, energised by the higher voltage, would switch your heaters within a few milliseconds.
