The DHF-1AC-2600W and DHF-1AC-5000W power supply units are advanced DC/AC inverters. They are developed for high efficient energy conversion from DC voltage sources.
Key features:
- Advanced DC/AC inverters
- Developed for high efficient energy conversion from DC voltage sources to grid compliant sinusoidal AC current in grid parallel operation
- Additional grid monitoring unit "ENS" available
- Bi-directional operation option
- Microcontroller
- RS485 interface
- OVP, OCP, OTP and short current protection
The DHF-1AC-2600W and DHF-1AC-5000W inverters are designed to draw DC currentfrom a DC voltage source. The DC voltage applied to the DC
input connector is internally measured.
They are equipped with two separate AC output connector sections:
- The AC output connector section is intended for connection to the AC utility grid
- The AC aux connector section is intended to be used for auxiliary AC
For applications in the German and similar markets, the inverter can be equipped with an additional grid monitoring unit "ENS", that establishes additional anti-islanding protection features due to local grid standards and codes (e.g. DIN VDE 0126: 4/1999).
All units are produced in compliance with ISO 9001 and therefore meet highest quality standards.

3 Maximum time of operation with 80 ADC: 10 minutes (due to thermal requirements).
4 The rate of change limitation of the DC current set point is realized by software control and not given by the analog current control
bandwidth of the DC/DC stage.
5 Limited by digital control of the DC power stage.
6 Limited by digital power control of AC inverter power stage; can only be reachedwhen both output connector sections (AC output and AC
