Since the establishment of the company in 1939, the company J. Schneider Elektrotechnik GmbH has become with innovations and growth to one of the leading suppliers of industrial power supplies for Transformers, DC UPS systems, and HV Power Supplies.
Customer requirements are in the focus for the development of high quality products. If transformers for renewable energy, DC UPS systems, HV power supplies, the requirements on our products are various. We manufacture as well products in series as customer specified products:
Transformers up to 10 MVA, customer specified transformers, starting transformers, reactors and filters, regulated and non-regulated power supplies, primary switched, stand-alone and 19“-versions.
UPS-systems (DC Battery and Capacitor based / AC UPS systems on capacitor basis).
Stand-alone units, 19“-version and built-in cabinet, battery chargers and magnetic voltage stabilizers.
Transformers: 100 VA – 10 MVA, power transformers, customer specified special transformers, starting transforners Reactors: filter circuit reactors, commutation reactors, smoothing reactors, sinus filters DC UPS-systems on capacitor and battery basis: stand-alone unit, 19“-version and built-in cabinet, battery chargers AC/DC-converter, DC/DC-converter and inverter AC UPS systems: on Capacitor basis Power Supplies: regulated, non-regulated, primary switched, stand-alone and 19“-versions, special power supplies High voltage power supplies: in high-current and high-voltage technique
To provide the optimum solution for the power supply for the most varied industrial needs is an enormous challenge. Either for control systems, highly elaborated machine applications such as ship building, tunnel construction, wind and solar energy or machine tools, we provide the suitable power supply, designed for your application. Single devices, products produced in series production as well as complete power supply systems with transformer and control are part of our product range.
J. Schneider is manufactur of High Voltage (HV) power supplies for high voltage and vacuum process applications.
The high-voltage power supplies are available for the output range from 1kW up to 120kW for output voltages of 150 V DC up to 150 kV DC. Plasma power supplies are available in the output voltage range from 400 V up to 2,5 kV as DC units and DC pulsed or bipolar.
2 in 1 solution:
DC-UPS systems (C-TEC with Ultra-capacitors and AKKUTEC for batteries) as energy storages are a 2 in 1 solution (power supply AC/DC and buffer). In case of an interruption of the power supply, the energy of the Ultracapacitors / batteries is released. The back-up time depends on the state of charge of the energy storage and on the discharge current.

To be protected against power failures, an uninterruptible power supply on AC or DC side is mandatory. The advantage of AC UPS systems is that this type is buffering all electrical consumers, eg. AC drives, etc. However, an AC UPS system is more expensive than a DC UPS system.
If the application allows to buffer only the 24V consumers in case of mains failures, a DC UPS provides a more economical solution.
On one hand no large capacities would be required and the dimensioning can be selected according the needs.
Also, the overall efficiency by using a DC UPS system is significantly better because a reconversion of the battery voltage into AC voltage and the repeated transformation in the required 24V DC voltage is not necessary. By using a DC UPS system the energy will be provided at where it is needed, namely, directly at the consumer without any "lossy indirections".
