Microtek EM4130+ Automatic Voltage Stabilizer for AC up to 1.5 ton (130V-300V), Metallic Grey – Digital Display, Wall Mounted

Good performance

good working

The media could not be loaded. Super

Absolutely garbage!The temperature sensor is malfunctioning on arrival and it starts to show oht (overheating) with only 8amp (1.5 ton 1700watt ac load)It also has lot of tripping problem and voltage variations causes annoying tripping

The media could not be loaded. Pros:1. Responsible onsite service2. Output always providing 200v to 250v even a input is 1603. Metal body4. Looks likes Cooper winding, however it's polished by Cooper coolant. So, it not sure Cooper or aluminium5. It have coolant fan. But fan always not running, it only running when all relays are function state.Cons:-1. More noise emitting when coolant fan run, other times no noise2. Have some lag to provide stabilized power supply(output power)3. Design is not good. If required then we need to pay extra Rs.380 for pearl model. It's a personal choice only4. Personally for my product alone, microtek logo is placed in correct position on the stabilizer.

All the best quality, all types are best quality

Value for money and good product.

Not suitable for my area. Returned it and purchased EM4160+ instead.Product specifications isn't complete for any stabilizer.It was the first stabilizer I purchased and this is what I came to know:1) There are two types of stabilizer in the market - Range based ( e.g Microtek, V-Guard, Candes ) and Target based ( e.g Aulten )2) All range based stabilizer has a effective range of 205v-245v. If voltage is inside this range then it will bypass the power supply. Adjustment (Boost/ Trim) takes place when voltage is outside this range and inside working range.(e.g EM4130 boost between 130v-205v and Trim between 245v-300v.3) All these stabilizers have a static transformer which is the main problem. So it can boost or trim a specific fixed amount of voltage. For example:-EM4130 ( 40v Boost/Trim approx)IP 204v - OP 244v, IP 190v - OP 230v, IP 250v - OP 210vEM4160 ( 20v Boost/Trim approx )IP 204v - OP 224v, IP 190v - OP 210v, IP 250v - OP 230vEM4140 and EM4150 got voltage adjustment around 30v approx and EM4170 got it around 10v.This is same for all other brands too like Vguard or Candes, that how these stabilizers work. Just check the working range and you will know the transformer capacity.# I don't know why there is no stabilizer with variable(not static) boost or trim option.## Voltage in my area stays around 200v that's why I went for EM4160. Thanks to Amazon for accepting the return.### I would suggest that, first you need to know average voltage in your area, for low voltage area200v-210v - EM4160 or EM4150190v-200v - EM4150 or EM4140180v-190v - EM4140 or EM4130For high voltage area do the math yourself.#### When stabilizer auto start boosting it's transformer stays active for atleast 10 seconds, so I was getting a high 249v output for 209v input from EM4130.*Aulten stabilizer runs the transformer all the time and output is based on 220v target +-17v. For example IP 215v - OP 232v, IP 225v - OP 208v.**I can't believe that I am writing this long review.
