TXVR isolated electronic voltage regulator
The TXVR is an isolated electronic voltage regulator (3.8 to 10 kVA) for facilities that need clean, stable, noise-free power — without batteries. It holds output within ±1% even as utility input swings from −45% to +45%, while a built-in galvanic isolation transformer eliminates common-mode noise and the need for costly dedicated circuits. A static transfer switch, LCD monitoring, ANSI/IEEE C62.41 surge protection, dual output voltages, a 3-year warranty, and TAA compliance round it out. When runtime needs change, the TXVR upgrades to a full UPS by adding firmware and external battery cabinets — a scalable path rather than a forklift replacement.

Precision power conditioning, no batteries required
The TXVR delivers isolated electronic voltage regulation, galvanic isolation, and surge suppression for facilities that need regulated, noise-free power rather than runtime. It is engineered for environments with severe voltage fluctuations, grounding issues, or electrical interference — where the problem is power quality, not outage backup. By regulating voltage electronically and conditioning power through an isolation transformer, the TXVR stabilizes operating conditions for sensitive loads without the cost, weight, and maintenance of a battery system.
±1% output across a −45% to +45% input swing
The defining capability of the TXVR is a very wide regulation window: it maintains output voltage within ±1% even when utility input varies by −45% to +45%. That covers the deep sags and surges that destabilize sensitive equipment in electrically challenging facilities — correcting them continuously, without drawing on a battery. The result is tight, repeatable output for precision loads in locations where the incoming utility cannot be relied upon to stay near nominal.
| Utility condition | TXVR response |
|---|---|
| Deep voltage sag (down to −45%) | Electronically corrected to within ±1% output |
| High voltage surge (up to +45%) | Electronically corrected to within ±1% output |
| Common-mode noise & grounding issues | Eliminated by the galvanic isolation transformer |
| Transients & surge events | Suppressed to ANSI/IEEE C62.41 Cat. A & B (6kV) with very low let-through |
Galvanic isolation that conditions power at the source
A built-in galvanic isolation transformer electrically separates the utility input from connected loads — and provides power conditioning during both normal and bypass operation. This mitigates the disturbances that degrade reliability in noisy or poorly grounded environments:
| Disturbance | How isolation addresses it |
|---|---|
| Common-mode electrical noise | Galvanic separation breaks the common-mode path between source and load |
| Ground reference instability | A stabilized ground reference supports sensitive equipment |
| Voltage transient propagation | Transients are attenuated rather than passed through to the load |
| Dedicated-circuit cost | Isolation removes the need to install expensive dedicated circuits |
Surge let-through is held under 10V normal mode (L-N) and under 0.5V common mode (N-G) at 6kV ANSI/IEEE C62.41 Cat. A.
What the TXVR delivers
Maintains output voltage within ±1% without batteries — clean, stable power conditioning rather than battery-backed runtime.
A wide input voltage window corrects deep sags and high surges from unstable utility conditions, keeping output tight where the incoming line cannot be trusted.
Eliminates common-mode noise and grounding issues and removes the need for expensive dedicated circuits, conditioning power during both normal and bypass operation.
Surge withstand to Category A & B (6kV / 200 & 500A, 100kHz ringwave) with ultra-low let-through — under 10V (L-N) and under 0.5V (N-G) at 6kV Cat A.
A static switch automatically transfers output to the isolated bypass source on overload or fault, and a manual maintenance bypass transfers the load to utility power for service.
Add firmware and external battery cabinets to convert the TXVR into a battery-backed UPS — a scalable path if runtime requirements emerge later.
The regulation tier of the isolation family
The TXVR is the no-battery member of the isolation family: it conditions and regulates power without providing backup. When runtime is required, the same chassis family steps up to the internal-battery TX91 and the external-battery, extended-runtime TX91L — and the TXVR itself can be field-upgraded into a UPS.
When you need regulation, not runtime
If the requirement is clean, regulated, noise-free power — rather than battery backup — the TXVR is the right tool. It avoids the cost, weight, replacement cycle, and footprint of a battery system while delivering isolation, wide-window regulation, and surge suppression. Where backup is required, the TX91 / TX91L add batteries to the same isolation approach, and the TXVR’s firmware-plus-battery upgrade path keeps that option open.
| Capability | TXVR (regulator) | Isolation UPS (TX91 / TX91L) |
|---|---|---|
| Voltage regulation | ±1% across −45% to +45% input | Regulated online output |
| Galvanic isolation | Integrated transformer | Integrated transformer |
| Battery / runtime | None — conditioning only | Internal (TX91) or external/extended (TX91L) |
| Best fit | Power quality where outage backup isn’t needed | Power quality and ride-through / continuity |
Upgradeable to a full UPS
Runtime requirements can change after a regulator is deployed. The TXVR is designed for that: by upgrading firmware and adding external battery cabinets, it becomes a battery-backed UPS — no forklift replacement, and a clean migration toward TX91L-style external-battery runtime.
Four models, 3.8–10 kVA
| Model | Capacity (kVA / kW) | Form factor | Topology |
|---|---|---|---|
| TXVR-3.8K | 3.8 / 3.8 | Tower | Electronic voltage regulation (no batteries) |
| TXVR-5K | 5 / 5 | Tower | Electronic voltage regulation (no batteries) |
| TXVR-6K | 6 / 6 | Tower | Electronic voltage regulation (no batteries) |
| TXVR-10K | 10 / 10 | Tower | Electronic voltage regulation (no batteries) |
All models provide unity output power factor, ±1% regulation, an integrated galvanic isolation transformer, and dual output voltages (240/120V or 230/115V) with an optional configurable PDU. The TXVR carries no batteries and provides no runtime — it is a power conditioner / voltage regulator, upgradeable to a UPS via firmware and external battery cabinets.
Where the TXVR is deployed
The TXVR is engineered for environments requiring precision voltage regulation and noise-free power — laboratory and scientific equipment, industrial and manufacturing automation, broadcast and media systems, research facilities and universities, retail and POS terminals, and any site with grounding issues, electrical noise, or input instability. It is the right choice where the priority is stable, isolated, regulated power rather than outage runtime.
TAA-compliant power conditioning
The TXVR is TAA compliant alongside UL1778, cUL, FCC Class A, and RoHS — suited to U.S. federal, government, and other regulated installations requiring Trade Agreements Act compliance.
