need a reliable AC to DC converter
(OP)
Good morning,
We need to purchase an AC to DC converter and need a recommended source for the following application. 200 HP compressor mild to moderate vibration. Clean environment, Secondary on main control Trans has been trended at 120 VAC +/- 5% we need to hold steady at 24 VDC. Load is under 200W, Ambient temp is 40 degree F to 100 degree F. Your thoughts and experiences are appreciated. Machine supplier has one but it is $770.00. Catalog's and web proves I can get it much cheaper. Unless I am over looking or not considering something. I replaced plenty but never sized one for myself so please be kind and learn me.

RE: need a reliable AC to DC converter
You are now telling us that the device needs 24 V DC?
I remember asking you about that before and you then said AC?
If you use transformer with an 18 - 20 V AC secondary and a bridge rectifier plus electrolytic capacitors, you will get your 24 V. I do not think that your comm equipment is very sensitive to supply voltage. What happened before is probably that it did shut down because of overvoltage or thermal problems (due to high voltage). Also,200 W seems to be heavy overkill for a communication device.
You had better check both supply voltage specifications and power consumption before taking any more steps. Especially if it is a 100+ or 1000+ thing. You may even need to talk to a consulting engineer to get it all right.
