AC voltage source and frequency converter
AC voltage source and frequency converter in one unit has been developed by Zentro-Elektrik to provide AC voltage as required by the public networks in most countries.
The requested frequency of the output voltage can be selected. The devices are available in the output classes 500VA, 1000VA, 1500VA, 2000VA & 3000VA. The respective voltage can be set between 0 and 270 VAC by a potentiometer on the front plate. The frequency is controlled by a quartz and can be switched between 50Hz and 60Hz or infinitely variable between 45Hz and 500Hz as an alternative. An active PFC in the input circuit of the voltage source reduces the harmonics to a value of only 0.8.
The AC source and frequency converter series ZAF offers extensive protection and control devices, such as overload protection, protection against short circuit, voltage-transient and undervoltage protection and a protection against thermal overload. The operating temperature is between 0 +50C at a relative humidity of <90%, non-condensing. Thus, not only its electrical data, but also its specific ambient conditions enable the device to be used in a wide range.
