What Is Stabilizer?
A stabilizer is a device that is used to keep electric appliances steady. It protects the appliances by providing a constant power supply even if there are some fluctuations in the supply.
Why Should You Buy A Stabilizer From PowerMax?
PowerMax Fitness's Vosta V3 Stabilizer is specifically designed for treadmills. It assures full protection against High Voltage, Under Voltage, Overload, Overheat, and Short Circuit. It is highly efficient and can be used for other home appliances also. Plus, It offers a 3-year domestic warranty too.
Comparison of three Kinds of AVR

Triac
(solid-state relay)
|
Electromagnetic Relay
(mechanical part)
|
Motorized Carbon Brush
(mechanical part)
|
|
Life of Switching Part
|
Highest
The technology of Triac is more mature, the triac is more reliable. Plus the “Zero cross transfer technology”, the life of triac is 2 or 3 times than the electromagnetic relay or the motorized carbon brush
|
Normal
The surface of the electromagnetic relay is limited, can’t pass big current. Can’t be used in AVR of big capacity
|
Normal
The motor is possible to be stuck, and carbon brush is worn part
|
|
Regulating Speed
|
Fastest
<50ms
|
Fast
<200ms
|
Slow
1-2s
|
|
Sparkle
|
No
No contact surface, there is no sparkle during the regulating process
|
Small
There is still small sparkle when contacts of relay switch
|
Big
There is big sparkle when the carbon brush moves
|
|
Noise
(Fan noise excluded)
|
No
Triac is a static relay, there is no noise during tap changing
|
Small
There is still small noise when contacts of relay switch
|
Big
There is a big noise when the carbon brush moves
|
|
User Replacement Part
|
No
|
No
|
Yes
User need to change the carbon brush after some time (e.g. 1-2 years)
|
|
Input Voltage Range
|
Wide
100-270V, 80-270V
|
Wide
100-270V, 80-270V
|
Narrow
Only 140-260V
|
|
Output Voltage Accuracy
|
High
Up to 4%
|
Low
10%
|
Highest
Normally 3%，up to 1%
|
|
Cost
|
High
Triac is expensive than an electromagnetic relay, and it requires extra protection circuit and heat sink, also it requires a heat sink, so the cost is higher than that of relay type AVR
|
Low
|
Low
The transformer can only
be made of copper, there
is an extra cost for motor
|
|
Afte-sale Cost
|
Normal
|
Low
|
High
Carbon brush needs to be replaced, the motor is not so reliable
