FAQ
Frequently Asked Questions
The most common questions about selecting regulators and transformers, custom manufacturing and the quotation process.
01What is a voltage regulator and what does it do?
A voltage regulator is an automatic protection device that keeps the voltage supplied to equipment close to its nominal value when mains voltage rises or drops. It protects machines, electronic boards and drives from failures and lifetime loss caused by voltage fluctuation.
02What is the difference between a servo and a static regulator?
A servo regulator corrects voltage steplessly and precisely with a servo-driven variac, but more slowly. A static regulator corrects in steps using electronic switches, very fast and with no moving parts. The choice depends on the load’s accuracy and speed needs.
03Are your products covered by insurance?
Yes. ONS Enerji products are covered by insurance for 2 years; in case of burn-out or failure, a payout can be claimed under the insurance cover. Scope, exclusions and the claim process follow the policy terms; please contact us for details.
04What is the difference between an autotransformer and an isolation transformer?
An autotransformer shares one winding between input and output; it is economical and efficient but gives no galvanic isolation. An isolation transformer has two electrically separate windings, providing safety and noise filtering.
05Do you manufacture custom kVA or voltage ratings?
Yes. We size and manufacture regulators and transformers to your load, input/output voltage and phase configuration. Simply share your details through the quote form.
