Chargery 1500W, 1200W, 600W and 400W RC power supply

I would like to recommend you S series of PFC power supply designed and manufactured by Chargery, the series are built-in Active PFC and all kinds of protection, 90~265VAC wide input voltage, and programmed wide output voltage.

ZVS Full-Bridge PWM with Synchronous Rectifier AC/DC control converter technology---an advanced converting technology, Chargery is the first manufacturer of use the technology design RC power supply--- assure up to 94% of efficiency. Not only save the power but also make the power supply smaller, easy to use and convenient to take.

S1500 can output 10-25V, rated 60A, 62A peak and 1500W maximal.
S1200 can output 11.5-24V, rated 50A, 55A peak and 1200W maximal.
S600 can output 6.0-15.5V, rated 40A, 45A peak and 700W maximal.

ok that's beautiful - this looks to be the daddy of power supplies

here's a test vid with the power supply driving 3 chargers simultaneously

test speaks for itself - this guy really pushes the power supply hard and its stable and solid

Hi!

Chargery power representative Jason was kind enough to send me one sample of the S1200 for my general opinion and some tests.

I made the video that "big bird" posted.

In the recent years, I have come across various power supplies, and some general information I have posted here.

I work in the quality assurence department in my company, so I have seen quite some flaws. This lead me to trust noone, and I usually take apart and check every servo, charger, and, of course, power supply that I get.

But first, there is an outside check.
The power supply comes in a sturdy cardboard box enclosed in a dense foam protection. Transportation damage is almost impossible. Also in the box is a manual and the biggest power cord I have ever seen.
Use this one - not, like me, a smaller one.
For giggles, go to 5:00min in the vid and watch my mishap with a smaller cord.

Everything on the outside is solid, nothing rattles. No loose screws, no gaps, everything is nice. On the bottom, there are big rubber feet to ensure a good stand.
So far, so good.

On the inside, everything looks good as well. The PCB looks clean and tidy. The soldering joints of all cables are inspiring confidence, and the ground contact is actually connected with the case.
No loose screws on the PCB either, and the nuts holding the fans are secured with threadlocker.

I like that no parts, like FETs or rectifiers, use the case as heatsink. This way it will not heat up. All power components are bolted to generous heatsinks at the inside of the case.

After putting it back together, I made a quick comparison with my WattsUp. Voltage and current were within 0.2V and 0.2A tolerance.

To check the behaviour under maximum output, I discharged all A123 packs I had. The bulk of the power will be used by my iCharger 3010B and my 5s10p A123 field battery.

For additional load, I connected my 208B and 1010B, both charging various 4s A123 packs in parallel.

I dialed the voltage to 18.0V, as this is the maximum the smaller chargers can take.
I started the charge on all chargers simultaneously, and one could see the current ramp up. It stopped at around 57A, which is even a bit over the rating. The fans came on quickly, but the air they blew out was only slightly warm. The cooling of this power supply is definitely on the healthy side.

It is nice to note that even with the maximum current, the adjusted voltage stays stable. The display flickered between 17.9 and 18.0V, which I consider stable enough for this world.

I am always interested on how things behave when they are driven to the edge. The behaviour in case of overload, user error, or unforseen incidences is always a hint on how much thought went into the design process.

So I lowered the output voltage a little. This forces the chargers to draw more current to keep the same output power. At close to 60A, the output voltage began to decrease sowly.
I consider this a very practical approach: For the charger electronics, a gradually reduced voltage is definitely healthier than a hard cutoff. Most chargers cannot provide the full power at a reduced voltage, so the load on the power supply will decrease automatically. iChargers can even be programmed to decrease their power when a specific input voltage level is undershot. If one programs this level to 1-2V under the level the power supply is adjusted to, this configuration will work with a great harmony.

To end the overloading of the power supply, I stopped one charger. Immediately, the voltage began climbing back to the initially adjusted level.

Very nice indeed! This is exactly the way a power supply should behave. No sudden cutoffs, but gentle movements to avoid the overloading.

During the whole charge process, none of the typical phenolic smell of overloaded electronics was noticable.

So, all in all, I can really recommend this power supply. Being versatile with it's adjustable voltage, it can both be used for lots of small and cheap chargers, as well as for high-powered ones needing a higher voltage to achieve their rating.

Cheers,

Julez

About PFC for 1200W power supply

About active PFC, there is a great explaination on the following link, http://www.rcgroups.com/forums/showp...1&postcount=19 and http://www.rcgroups.com/forums/showp...1&postcount=25 by Mark.
for S1200, if 110Vac input voltage and 1000W charge, the maximal input current is 1000W charge / .99 (PS power factor) / .92 (PS conversion efficiency at 110V) / .8 (charger DC-DC converter efficiency) / 110V (line voltage) = 12.47 amps.
if no active PFC or no PFC, when 1000W charge, the input current will be 19A, so if 110V/15A is stardard socket, the 1200W power supply must be with PFC and PF >0.95.
