GBK2 Single Phase 220v To 220v Toroidal Balanced Isolation Transformer 300va-2Kva

Why GBK2? Key benefits at a glance

• True galvanic isolation: Separate primary and secondary windings eliminate a direct conductive path between mains and load—improves safety and reduces ground-loop noise.

• Toroidal core advantages: Higher efficiency, lower stray magnetic field, compact footprint and very low mechanical hum.

• Clean power: Effective common-mode noise suppression and transient filtering for precise, reliable operation of sensitive equipment.

• Built-in protection & monitoring: Models include multi-protection features (over/under-voltage, overload, short-circuit, over-temperature, time delay) and an LCD for easy status monitoring.

• Tested & traceable: Factory hi-pot, insulation resistance and turns-ratio tests available on request—supports procurement & compliance checks.

• Competitive isolation transformer price: Optimized design and manufacturing enable excellent price/performance across the 300 VA–2 kVA range.

Technical Parameters

Typical applications

• Medical and diagnostic equipment

• Professional audio/video systems and broadcast gear

• Laboratory and test instruments

• Precision industrial control and automation

• Sensitive office electronics and server rooms

Installation & commissioning highlights

• Mounting: Secure toroidal unit on recommended bracket; maintain clearance to reduce stray field coupling.

• Earthing: Connect protective earth to the designated frame terminal. If you need a grounded secondary neutral, consult our engineering notes—grounding reduces isolation benefits.

• Protection: Fit primary-side overcurrent protection sized for rated current and inrush. Consider soft-start or inrush limiting for large loads.

• Acceptance tests: Perform continuity, insulation (megger) and turns-ratio (TTR) checks; compare to factory reports. Hi-pot testing should be done only by trained technicians.

What affects isolation transformer price?

The isolation transformer price for GBK2 models depends on: VA rating (material cost scales with copper & core), toroidal core grade, copper vs. aluminum conductor, custom voltages or taps, enclosures and connectors, required certifications (IEC/UL), and order quantity.

FAQs

Q1 — Why choose a 220V → 220V isolation transformer instead of a filter or surge protector?
A dedicated 220v to 220v isolation transformer not only attenuates noise and surges but also provides galvanic isolation—breaking ground loops and offering a higher level of safety for service and measurement. Filters or surge protectors complement but do not replace galvanic isolation.

Q2 — Are toroidal isolation transformers quieter than laminated types?
Yes. Toroidal cores produce significantly less mechanical hum and stray magnetic field than traditional EI cores, making them preferable in audio, medical and lab environments where noise and interference must be minimized.

Q3 — Can you provide certified test reports and volume pricing?
Yes. We supply factory test reports (hi-pot, IR, TTR) with each shipment and offer tiered pricing for bulk orders. Contact our sales team with model, quantity and any certification requirements for a fast, transparent quotation.
