Supporting motors up to 8kW and 50A inrush current, it offers adjustable soft start times (0-30s) to reduce mechanical wear and electrical stress. Compatible with 220V, 230V, and 240V motors, it replaces traditional starting methods with a sleek, efficient solution ideal for pumps, fans, conveyors, and compressors across diverse industries. ## Description This product is commonly used for motors with the following voltages:220V.(50Hz,60Hz).230V.(50Hz,60Hz).240V.(50Hz,60Hz).The above three voltages are universal for this product.Single-phase 220V soft start module use range:Petroleum,chemical,fire,construction,metallurgy,building materials,mining,environmental protection and other fields.Fans,pumps,belt conveyors,ball mills,car washing machines,conveyors and compressors.It is an ideal replacement for traditional star/delta conversion,auto-coupling buck,magnetic control buck,inverter and other step-down starting devices.220V single-phase motor soft start module(motor conversion method)model:SSR-20WA-R1(1kw)SSR-40WA-R1(1.5kw)SSR-60WA-R1(2kw)SSR-100WA-R1(4kw)SSR-150WA-R1(6kw)SSR-200WA-R1(8kw)According to the actual working current 5 times:power÷voltage×5in case:Your motor is 8000w power÷220v voltage ×5=(181.81WA should choose 200WA)should choose the parameter closest to that model.our soft start is universal for the motor,regardless of whether the motor has a capacitor or not.If your motor is working for a long time,the motor above 2000W needs to be equipped with a heat sink.Single phase motor compared to starter moduleVoltage compatibility:(220V+0V=single-phase 220V,AC)(230V+0V=single-phase 230V,AC)(240V+0V=single-phase 240V,AC)(220V+220V=two-phase 380V-400V,AC)Frequency:50Hz,60HzSoft start time is adjustable between 0-30 seconds (soft start time refers to the entire process 0-220V,0-380V)Slowly adjust the starting voltage from 0-50?Reaching the rated voltage (220-380V)There are two ways to use it:1.After closing the switch,the main power will be energized and start soft start.2.Use the switch to control,close the soft start to start,open to stop.The soft start module has 2 programs:1.SSR-40WA-R1 has soft start and no soft stop.2.SSR-40WA-R2 h Review: Five stars, but with a few quibbles - I installed this on my water well and now it can start when running on solar battery backup. Inrush amps went from about 70 to 30. I could have adjusted it lower, but have read that water well pumps can fail prematurely if they don't come up to speed quickly. I get pressure in about a second. For longevity concerns, I only plan on using this during power outages so I will install a bypass switch. The seller says I can use jumpers across the input and output terminals and it won't harm the device. That's much simpler than using a 4 pole switch to isolate it. I bought the 4Kw version. My well draws 12 amps steady state and the soft start gets warm so I will add a heat sink. That's where my first quibble comes in. It will be difficult to mount this inside an enclosure and also have a heat sink because of the way the mounting holes are arranged. I may try to find an aluminum enclosure that will provide heat sinking and also make it easy to add a heat sink on the outside. The other quibble is the adjustments. As others have said, there is no manual. I learned that the time adjustment has more effect on the inrush than %. BTW, increasing the time reduces the inrush and surprisingly, increasing the % increases the inrush. I have mine set to 2.5 seconds and 50%. Other than that it worked great in initial testing. Time will tell how robust it is. ## Features - Single-phase 220V soft start module use range - Petroleum,chemical,fire,construction,metallurgy,building materials,mining,environmental protection and other fields. - Fans,pumps,belt conveyors,ball mills,car washing machines,conveyors and compressors. - It is an ideal replacement for traditional star/delta conversion,auto-coupling buck,magnetic control buck,inverter and other step-down starting devices. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09HKXL2V3 | | Amperage | 50 A | | Best Sellers Rank | #295,943 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #125 in Motor Drives | | Brand | Topffy | | Brand Name | Topffy | | Customer Reviews | 5.0 out of 5 stars 1 Review | | Horsepower | 1.5 KW | | Item Weight | 1 g | | Manufacturer | LDSKHSH | | Material | Metal | | Material Type | Metal | | Model | SSR-100WA-R1 | | Number of Items | 1 | | Part Number | LDSKHSH322 | | Unit Count | 1 Count | | Voltage | 230 volts, 240 volts | | Wattage | 8000 watts | ## Product Details - **Amperage:** 50 Amps - **Horsepower:** 1.5 Kilowatts - **Item Weight:** 1 Grams - **Material:** Metal - **Voltage:** 230 Volts, 240 Volts ## Images ![220V Single-Phase Motor Soft Starter Module controller2KW4KW6KW8KW Motor Online Soft Starting Fan Pump Pressure Reducer Conveyor (Color : SSR 100WA R1(4KW)) - Image 1](https://m.media-amazon.com/images/I/41p8Q2yYrGS.jpg) ![220V Single-Phase Motor Soft Starter Module controller2KW4KW6KW8KW Motor Online Soft Starting Fan Pump Pressure Reducer Conveyor (Color : SSR 100WA R1(4KW)) - Image 2](https://m.media-amazon.com/images/I/41SDJMNANZL.jpg) ![220V Single-Phase Motor Soft Starter Module controller2KW4KW6KW8KW Motor Online Soft Starting Fan Pump Pressure Reducer Conveyor (Color : SSR 100WA R1(4KW)) - Image 3](https://m.media-amazon.com/images/I/41RjYgp7wIS.jpg) ![220V Single-Phase Motor Soft Starter Module controller2KW4KW6KW8KW Motor Online Soft Starting Fan Pump Pressure Reducer Conveyor (Color : SSR 100WA R1(4KW)) - Image 4](https://m.media-amazon.com/images/I/41+kAg2yKFS.jpg) ![220V Single-Phase Motor Soft Starter Module controller2KW4KW6KW8KW Motor Online Soft Starting Fan Pump Pressure Reducer Conveyor (Color : SSR 100WA R1(4KW)) - Image 5](https://m.media-amazon.com/images/I/41yCjHgWOMS.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Five stars, but with a few quibbles *by L***H on July 21, 2024* I installed this on my water well and now it can start when running on solar battery backup.
