Where our windings end up
A transformer for a power amplifier and one for a hospital bed share a core and live two different lives. The standard changes, the test changes, the way the report is written changes.
Professional audio and high fidelity
The toroid was born here for a reason: almost no stray field and no mechanical hum passed to the chassis. We build supplies for power amplifiers, preamplifiers and studio racks.
- Electrostatic shield between primary and secondary
- Matched symmetrical secondaries
- Impregnation against mechanical hum
- Tight regulation at full load
Medical equipment
Here the separation between mains and patient is not a good idea, it is a requirement. We work to the manufacturer specification with double insulation and verified clearances.
- Reinforced insulation to customer specification
- Low leakage current
- Test report for every batch
- Batch number traceability
Lighting and architectural
Supplies for extra low voltage luminaires, transformers for halogen lamps and for museum and outdoor lighting runs, where the envelope matters more than anything.
- Low height for ceilings and coffers
- Integrated thermal protection
- Potting for damp environments
- Low noise in quiet rooms
Automation and industrial panels
Control and isolation transformers for panels, line reactors for drives, common mode chokes to cut the noise inverters push back onto the supply.
- Thermal class F or H
- Terminal block terminations
- Reactor sized on the drive
- Central bolt mounting on a plate
Measurement, laboratory and test
Current transformers, reference windings, coils for test benches. Small quantities, tight tolerances, documentation required almost every time.
- Stated tolerance on the ratio
- Calibration on the sample
- Quantities from one piece
- Signed data sheet
Power, charging and conversion
Filter inductors for converters, reactors for charging stations, isolation transformers for installations where separation from the mains is part of the safety case.
- High direct current without saturation
- Iron powder or sendust cores
- Thermal check under real load
- Fixing that holds under vibration
Your sector is not on the list
The list describes where we most often end up, not where we can reach. If the part winds onto a toroid, it can be made.
