Product Description
High Voltage Low Loss UR70 Transformer Stable Insulated for Ozone Generator
Product Overview
The UR70 High Frequency Transformer is a customizable U-core magnetic component designed for high-voltage energy conversion, isolation, pulse generation, and resonant power applications. The open U-shaped ferrite core structure provides a large magnetic path and accessible winding area, supporting cylindrical bobbins, sectional windings, extended insulation distances, customized core gaps, and external high-voltage leads.
The following values represent common project-discussion ranges used by international buyers when evaluating a UR70 high-frequency high-voltage transformer. They are application references rather than fixed guaranteed ratings for every UR70 transformer.

Customization Capabilities
Chipsen can customize input voltage, output voltage, output current, power, switching frequency, topology, duty cycle, primary inductance, turns ratio, leakage inductance, DCR, peak current, core material, core gap, winding sections, conductor type, insulation voltage, creepage clearance, corona margin, partial-discharge limit, high-voltage leads, terminals, mounting frame, potting, dimensions, labeling, and production-test requirements.
Platform Flexibility
UR70 identifies the magnetic-core platform rather than a fixed high-voltage rating. Transformers using the same UR70 platform may have completely different specifications including:
- Input voltages
- Output voltages
- Output currents
- Power levels
- Switching frequencies
- Converter topologies
- Primary inductance
- Turns ratios
- Leakage inductance
- Core materials
- Core gaps
- Winding sections
- Insulation systems
- High-voltage lead wires
- Potting materials
- Mounting structures
- External dimensions
Product Construction
| Construction Item | Standard Reference or Custom Option |
|---|---|
| Core Platform | UR70 U-shaped high-frequency ferrite core |
| Magnetic Structure | Two U-core sections forming a closed magnetic path |
| Coil Structure | Cylindrical bobbin or custom sectional winding former |
| Core Material | Application-specific ferrite material |
| Core Gap | Ungapped or customer-defined air gap |
| Primary Conductor | Magnet wire, multi-strand wire, or Litz wire |
| High-Voltage Winding | Fine magnet wire, sectional winding, layer winding, or customer-defined construction |
| Winding Arrangement | Separated, interleaved, sectional, or controlled-leakage structure |
| Interlayer Insulation | High-voltage tape, film, paper, sleeving, or customer-approved dielectric material |
| Insulation System | Functional, basic, supplementary, double, or reinforced insulation |
| High-Voltage Lead | Silicone cable, PTFE cable, insulated flying lead, or customer-specified HV wire |
No fixed mechanical dimensions should be assumed from the UR70 model alone. Core dimensions, bobbin length, winding envelope, lead positions, mounting-hole locations, base dimensions, weight, and insulation distances must be confirmed through the approved customer drawing.
Product Characteristics
High Voltage Capability
The turns ratio, winding sections, insulation barriers, creepage clearance, lead-wire insulation, and potting structure can be developed around the required working voltage and dielectric-test level.
Custom Output Voltage
The secondary winding can be designed for high-voltage AC, pulsed output, or use with an external rectifier and voltage-multiplier circuit.
Sectional Winding Options
A sectional bobbin or divided winding structure can distribute voltage stress and reduce the voltage difference between adjacent winding layers.
Low Parasitic Capacitance Options
Winding sections, spacing, shield arrangement, and winding sequence can be adjusted when the application requires reduced capacitive coupling or lower common-mode current.
Controlled Leakage Inductance
Leakage inductance can be reduced or intentionally controlled according to the resonant circuit, pulse shape, current limiting, switching stress, and snubber design.
High Isolation Design
Insulation tape, film barriers, sleeving, high-voltage wire, impregnation, and potting can be selected according to the required working voltage, impulse stress, environmental conditions, and safety standards.

Frequently Asked Questions
Q1: Is UR70 a fixed output-voltage or power rating?
No. UR70 identifies the U-core platform. Actual output voltage, power, and insulation capability depend on turns ratio, frequency, topology, winding structure, materials, cooling, and dielectric design.
Q2: What information is required for quotation?
Please provide input-voltage range, converter topology, switching frequency, duty cycle, required output voltage, output current, power waveform, primary inductance, leakage target, working voltage, dielectric-test voltage, environment, lead requirements, and mechanical drawing.
Q3: Can the output voltage be customized?
Yes. The turns ratio and winding structure can be developed for the required high-voltage AC or pulsed output. Specify no-load voltage, loaded voltage, allowable regulation, and output-current limit.
Q4: Can the transformer provide high-voltage DC directly?
The transformer normally provides an AC or pulsed output. High-voltage DC generally requires an external rectifier, filter, or voltage multiplier. Information about this circuit and load must be included in the design review.
Q5: Can the primary inductance be customized?
Yes. The target value, tolerance, measurement frequency, measurement voltage, and operating conditions should be included in the approved specification.
Q17: What is the MOQ?
The MOQ shown for this UR70 product is 100 pieces. Final prototype and production quantities depend on materials, bobbin, winding construction, insulation, potting, and project requirements.
Q18: How long do quotation and sample production take?
Quotation target is within three days after complete requirements are received. Sample production can be targeted within seven days after the drawing, electrical specification, materials, and construction are confirmed.
