Default 24V power supply

Does anyone have experience with new Revolectrix 24V 55amp power supply?
I was going to order a couple, but it became out of stock until March (another mond & a half).

Any other power supplies? eFuel 24v looks good with adjustable voltage, but no feedback on it.

I have more than large enough power supplies on 12v type (55 & 75amp from Iota)

A friend at my flying field has an eFuel 24V adjustable supply and it has worked well for him for the last couple months.

I believe you can run your Iota's in series for 24V supply, however, I don't know if you can use different models (55A and 75A) together. I have no experience or knowledge about the Revolectrix supplies.

Woodie,
Good to hear that someone is using the efuel without problem.
Do you know which charger he uses with the efuel 24v power supply?

Iota can be used in series. However, it becomes really heavy although they are really good. I've had at least 3 of 55amp. Sold two and kept the first ont that I bought. It's been working good for the past 7 years without a problem.

My 75 amp Iota is brand new in box. Thinking about selling it to get the 24v.

Hi Robert,

Do you know if it can be used on 240V 50Hz power?

Thanks,

Robert,

good. I will bring a couple in. Still waiting for Revolectrix power supply info.
I also sent you an e-mail.

Chad,

Below is the spec of efuel. I will have to talk to EmpireRC about the input voltage selection. Not completely sure if the version they have is input selectable.

Total Output Power: 1200Watts
Voltage: 100-120V AC (PSU 60ADE); 200V-240V AC (,PSU 60ADU)
Input AC Frequency: 50Hz/60Hz
Output Voltage: 15-24V DC±1V
Output Current: 60A±3A @ 20V DC; 50A±3A @ 24V DC
Current Overload Protection: 63A
Input Fuse: 100-120V AC 25A Fuse; 200V-240V AC 15A Fuse
Output Voltage Ripple: <200MV
Power Efficiency: >85%
Power Factor: >0.7
Over Temperature Protection: <65?
Cooling Method: Cooling Fan
Operating Temperature: 0-40?
Operating Humidity: 0-90%
Dimensions (L*W*H): 305x140x78mm
Net weight: 2.52kg

Ive been using the Icharger 24V PS for a season without problems. According to the manual its 90-265V AC 50/60Hz compatible. I think Progressive import it to US.

One small point to draw the full 50A(55A Max) into one charger you need to make up some parallel connectors as each set of terminals is rated to 25A

Thanks, would be great if you could find out, I have been unable to confirm if you can switch it or not.

Another option is the Chargery S1200 variable power supply. I bought mine from Neu Motors last summer and it has performed without issue. Specs say is will take 90-265V 56-60 cycle. My only complaint is the Amp/Volt display could be a little brighter to view in direct sunlight but it is a minor thing.

The power cord is a PC type cord, 3 connector, no switches for voltage select. So I guess it runs on whatever the input voltage is.

Here is a link to page with the item.

There is a thread on the 'other' website/forum with details on the power supply. Here is a link you will need to 'fix' (replace 'dot' with '.') to get it to work.

HI Chad,

When you see an input on a power supply that states 90-265v 50/60 cycle it is called a "universal input" it is pretty much common all most of your power supplies and really eliminates the input issues. However, you need to realize when you have 90 v input your input current is much higher vs an input of 265 v with much lower current. The Universal inputs usually have a wider regulation range due to the wide input. The worse case situation is 90 V @ 50 Hz. That has the highest input current and usually the worse regulation.

Chad are you guys going to get down to the canam this year? I am partially retiring and would love to come up to a contest in your area. Weather and cost of fuel permitting.

So far, I can't verify if the eFuel from Empire can be used 240V 50Hz.
Empire was out of stock when I try to get those. Waiting for those to come in for verification.
