Schäfer Elektronik GmbH products

The IV Series of DC/AC inverters. The design of the IV Series synchronizes three individual switch mode inverters and three output transformers, for a symmetrical 3-phase output. The transformers provide input/output isolation, while transforming the voltages to user required outputs.

Low Power Converter with natural convection from 100W to 7.5 kW.

AC-DC High Power Converters with temperature-controlled fans from 5kW to 30kW.

40000W DC/DC Converters, AC/DC Converters and Battery Chargers. The DC/DC Series boasts 2 DC input ranges of 320-640 and 450-800V with 10 single output voltages ranging from 23VDC to 800VDC. The AC/DC Series offers the same range of output voltages from 3-Phase VAC input. The Battery Charges provides output voltages ranging from 24VDC to 290VDC.

Frequency converters, single phase output from 500 VA to 15 kVA or 3-phase output from 1,5 kVA to 45 kVA.

The PB-SERIES are an active harmonic filter system for large buildings as well as automation, wind-turbine and various other industrial applications eliminating harmonic oscillations and consequently costs for reactive energy. The filter monitors the current signal and compensates for the unwanted elements of the measured current. Thus, the filter ensures a harmonic suppression independently of the number of loads. Furthermore the filter corrects the power factor, improving the system efficiency while reducing harmonic pollution.

DC Input voltage: 10 - 800V DC. AC Input voltage: 115 / 230V AC, single phase (with or without PFC) or 200 / 400 / 480V AC, three phases. AC Input frequency: with PFC 47 - 65Hz, without PFC 47 - 400Hz. Output voltage: 5 / ... / 400V DC. Output current: up to 500A. Output power: 100W - 7.5kW.

SCHAEFER designs and manufactures high reliable and robust power supply solutions for “multi-mission air surveillance” radars.
