Used Voltage Regulators

This category is for used single-phase and three-phase voltage regulators. For servo-controlled, static or stepped voltage regulators, compare kVA capacity, input/output phase configuration, input voltage range, required output voltage, regulation accuracy and load characteristics. Units with the same capacity may differ in input range, overload limits and response characteristics; verify the full model number.

Check load current, any starting current, bypass arrangements and protection functions. See the voltage regulator selection guide for details. For backup during outages, consider the difference between a regulator and a UPS. Used UPS units and power supplies have separate categories; new equipment is listed under new voltage regulators.

To buy, browse the product listings in this category. Your seller is the store identified on the product page. Confirm price, availability, delivery, specifications and condition with that store; listings should not all be treated as DERELL's own inventory.

Distinguish between used, unused, boxed, repaired, faulty and parts-only items. Known faults, missing accessories, bypass condition and any available maintenance history must be disclosed. State the test load percentage and input/output measurements; a no-load check must not be described as a load test. Test coverage, any warranty and declarations of standards compliance depend on the store's product description. A boxed or unused item does not automatically come with a warranty.

To offer a voltage regulator for sale, email the brand, full model number, quantity, working or faulty condition, clear photographs of the unit and its nameplate, and your asking price to otomasyonavm@gmail.com. Include capacity, phase configuration and input/output voltage details. We do not purchase products without an invoice. A submission is neither a commitment to buy nor an automatic listing service.

Listings are updated approximately every 10 days. A sold item may remain visible briefly, so confirm availability with the selling store before ordering.
