Using air/solid insulation, the STS high-voltage transformer galvanically isolates a 400 V mains supply to 3.5 kV. Furthermore, the partial discharge free insulation system, supports a long lifetime.

Key Data
P = 0,5–5,5 kW
F = 47–60 kHz
Dimensions: 71 x 71 x 70 mm (L x W x H)
Weight: 1 kg

The STS production system ensures that items produced in series meet reproducible, high quality standards. Taking into account market-specific standards, this ensures that they function reliably even in highly sensitive fields of application.

Key Data
P = 58 kVA
F = 60-80 kHz
Dimensions: 152 x 129 x 155 mm (L x W x H)
Weight: 9.1 kg

Using the latest core technologies, power transformers can also be optimised for power density at higher frequencies. The optimised thermal management system implemented in the transformer directs losses directly from the hot spot of the component to the heat sink via the bottom of the housing – as a result, only < 20 % of losses distributed inside the converter.

Key Data
P = 500 kVA
F = 20-50 kHz
Dimensions: 300 x 220 x 400 mm (L x W x H)
Weight: 50 kg

Through the direct water cooling of the winding, the transformer can be highly efficient cooled. 2,000 W losses at 500 kW transmitting power.

Key Data
P = 650 kW
F = 12 kHz
Dimensions: 670 x 315 x 500 mm (L x W x H)
Weight: 125 kg

High voltage insulation between the primary and the secondary winding is achieved by ensuring the optimal distances between the coils. This leads to a partial discharge extinction voltage greater than 7 kVac (<200 pC). Cooling system: forced air cooling > 4 m/s.

Key Data
P = 100 kW
F = 25 kHz
Dimensions: 290 x 168 x 125 mm (L x W x H)
Weight: 15.8 kg

Optimised winding design and tailored core technology permit a low winding capacity in combination with a flat design

Key Data
P = 45 kW
F = 32 kHz
Dimensions: 150 x 90 x 100 mm (L x W x H)
Weight: 5.2 kg

Thanks to an optimised winding design and tailored core technologies the power density of the transformer can be increased: 8.4 kW/kg!

Key Data
P = 450 W
F = 350 kHz
Dimensions: 60 x 60 x 45 mm (L x W x H)
Weight: 400 g

High voltage transformer (up to 4.5 kV secondary voltage) at high frequency and high pulse power (4 kW at 1 minute).
