ABSTRACT:
This is a stabilizer which
constantly monitors the output voltage and controls the variations in the input
voltage by movements of a motor. This motor in turn selects the proper output
voltage on the variable transformer (variac). This is probably the cheapest
power-conditioning product available. It gives reasonably good
voltage regulation and is all right where voltage fluctuations are not
considerable. However it is not advisable to use it outside big cities where
apart from considerable fluctuations in voltage, the power is full of frequency
drifts, failures, noise and spikes.
Use of Servo
Stabilizer is the only way to control erratic supply voltage conditions. Servo
Stabilizer can control all types of loads i.e. inductive, resistive, capacitive
loads. Other voltage stabilizers viz. Constant Voltage Transformers or Static
Voltage Stabilizers cannot be used in such applications. Servo Stabilizers are
available from 1 KVA 1 ph. to 250 KVA 1 ph and 3 KVA 3 ph to 2000 KVA 3 ph. 3
ph. Servo Stabilizers can be for balanced or for unbalanced input voltages. Servo Stabilizer has four
major components
- Driver
Unit
- Motorized
variable voltage auto transformer
- Double-wound
Buck Boost / Series transformer
- Servo
controlled sensing card (PCB)
After determining Input voltage band and load of
customer we design our servo stabilizer to take care of the minimum and maximum
voltage fluctuations. While ordering servo stabilizer care should be taken to
ensure that servo stabilizer capacity is 20% more than maximum load. In servo
stabilizer determine output is determined voltage and the same is set by means
of servo controlled sensing card (PCB). Whenever change in output voltage which
occurs due to change in Input voltage, the servo controlled sensing card (PCB)
gives signal to the motor fitted on variable voltage auto transformer to either
increase or decrease the output voltage to achieve the predetermined output
voltage.
I have read the article, it contains clear and useful information. Thanks for the post.
ReplyDeleteServo Stabilizer provides perfectly stable output even under severe conditions of unbalanced voltage conditions. Ideal to protect the electrical and electronic equipments from high and low voltage. Servo Voltage Stabilizers are in high demand to save your expensive electrical devices from damage. One time investment of customer in this product can save his/her expensive appliances.
Even I purchased a servo stabilizer for my home appliances from SERWEL it has very good features. It helped me to save my expensive applications
