1650 Series
1650 Series
Voltage and frequency converter

Single or three-phases
The frequency and voltage converters of the 1650 series are designed for the simulation of aviation 400 Hz and 800 Hz grids, international single and three-phases grids (e.g. 50 / 60 Hz) with variable voltages and frequencies. The converters are custom-made and have, for example, switchable ranges of common sizes.
Foreign grids
Frequency converters are used to supply consumers that require a different frequency
and possibly voltage than the available mains supply has, e.g. 400 Hz at a voltage of 115 V.
Modular design
The frequency converters are constructed with mains rectifier and inverter. The mains rectifier is designed for mains supply and the inverter supplies the desired output frequency and voltage in one or three phases.
The output of the converters is galvanically isolated from the input and is manufactured with powers from 500 VA to 50 kVA. They prove themselves in continuous operation under the toughest industrial conditions. These devices have a significant economic efficiency due to their well thought-out concept.
- Three phases to one phase of higher power can be combined (e.g. 3x 10 kVA to 1x 30 kVA)
- Very robust design for industrial environment
- Power from 500 VA to 50 kVA, 1- or 3-phase
- Short-circuit proof and overloading
- Galvanic isolation
- For supplying alternating voltage consumers with different frequency and voltage
- Output e.g. 115 V 1-phase, 3x 120 / 208 V 3-phase, other values up to 750 V are possible
- 16 2/3 Hz, 50 Hz, 60 Hz, 300 Hz, 400 Hz, 800 Hz fixed and adjustable
- Efficiency 81 to 92 %
- Switch-on current limiter with monitoring
- Indicator LEDs for operating states
- 1x signalling contact operation (fault)
- Structure selectable depending on power on Mounting plate or in wall-mounted, floor-standing rack, 19 ” full insertion
- Input and output fuses
- RS232 and LAN interface optional
