EasyStart™ 368 Soft Starter for AC Units 30K to 48K 230V - ASY-368-X48
EasyStart by Micro-Air is the most effective way to reduce current draw of marine air conditioners or refrigerators. It was designed with a 4-part start ramp sequence that is self-optimizing, resulting in the lowest possible start-up current. It is compatible with all boat air conditioning brands like Dometic, Webasto, Cruisair, Marine Air, etc. EasyStart can deliver a start current reduction of up to 75% of a compressor's LRA (locked-rotor amperage) allowing your marine air conditioner to work in situations where it otherwise would not have functioned.
Sart-Up Algorithm for Start Surge Reduction
- Lab tested CE Compliance
- Average start surge reduction to 65%
- Sophisticated, auto-learned 4-part start-up algorithm
- one time learning algorithm for better shore power/generator transitions.
- Individually optimized profiles for 50Hz and 60Hz
- Low sensitivity to momentary voltage deeps during start-up
- Auto-bleed of run cap voltage and compressor energy during shutdown
- Reliably starts any 115V compressor on a Honda EU2000i in ECO Mode.
This sucker works good and cut the starting amps in half. Water Yacht solutions is a good place to purchase it from and cheaper than micro air.net. I’m very happy with the soft starter and it was fairly easy to wire up.
Fast shipping & great product. Installed on my central air 4 ton unit and dropped my inrush amps from 56 to 29amps and can now start the a/c easy with my generator. Installation is easy and there are a ton of Youtube videos on how to install it if you need a visual aide.
This is a bit expensive but worth it. Wiring instructions were easy to understand and once it learned the startups, it took my inrush current from 60 amps all the way down to 16.4. In a power failure, I’m using a Westinghouse wgen9500DF on propane to start this 3 ton A/C & now the gen barely notices when the compressor starts up. Compressor is also much quieter when it starts so should add years to its life. Overall I’m happy with the purchase.
I wanted to use this on my 3.5 ton A.S. A/C unit so I could limit the starting current for use with a generator. I was concerned that this might not work, as online docs for my unit state that it uses a "non bleed TXV". Contacted the factory and they said that although these types bleed down more slowly than the orifice types, they have success in 99% of these situations. They were right! Plunked down the money (by the way this site had the cheapest online price I could find), installed it (fit inside the cabinet) and it worked fine. I did not have the means to measure inrush current, but the nameplate on the unit stated LRA was 109 amps. The first learning cycle showed starting amps 50, and after the remaining 4 learning cycles it was down to 30. Runs off the generator with hardly a blip.
Great product. Fast shipping. Easy installation. No more Compressor clunking on and off all night.
Downloaded the instructions. Use my Fluke to check Inrush amps prior to installing on my 4 ton Carrier unit, and they were 119amps. Installed Easystart, and clamped my meter back on. First reading I got was 020 and the unit didn't run but a minute or so. Thought I did something wrong. (I only lowered the thermostat 1 degree to make it come on. It cooled down and turned back off). After reviewing my installation and determining I had it correctly installed, I tried it again. Inrush amps were 15amps. (The 020 was actually telling me it read 20 amps, but I guess I didn't believe it). Running amps didn't change. They were 10amps before and after Easystart. I haven't connected my generator to make sure it will work, but I can't imagine it won't, now. 20amps is only 4800 starting watts. I'm a happy camper so far! I will come back to change my review if anything changes!
I just hooked up the ASY-368-X48-Blue to my 4-ton Trane/American Standard A/C. Installation went flawlessly following the Micro-Air instructions. Before installation, I measured Inrush current with an “Inrush” capable Clamp Meter and Inrush was - 118.4 Amps. After Installation and 5 start learnings by EasyStart startup Inrush current has been measured several times and shows - 35.2 Amps. Tried also with my WGen9500/12500DF starts and runs perfectly, also remaining plenty of power to run the everything I need in my house.
Expensive but works as advertised. Dropped 48K unit from 68.6 amps down to 34.7 amps at startup(using Fluke clamp on ammeter) after the 5 learning starts on utility power. Run amps are not altered at about 17.2 amps. If your lights blink when the AC comes on or you're trying to run on backup/generator power, this will help you out.
