SYFU50 231/400V 50Hz

This unit is used for synchronization with the public power supply system and for voltage and frequency control for off-mains operation. As a result of the short reaction times used in frequency and voltage control and in synchronization, the unit is especially suitable for gensets with short rev-up times and gas turbines. All inputs and outputs have a high potential separation and the output contacts are dimensioned for low-voltage use and equipped with internal spark quenching capacitors. All relevant settings can be changed and stored permanently by the customer via easy-to-use menu control and an LCD display. All current voltage and frequency values are displayed during operation. The monitor control of the unit is equipped with safety functions such as a watchdog and a key code function to prevent unauthorized alteration of the par

SYFN30 231/400V 50Hz
This unit is used for the parallel connection of generators with the mains and includes a static frequency control for the generator. It is equipped with preselectable advance time ( generator switch delay ), frequency difference and voltage difference. The output pulses for the frequency adjustment of the generator can be adjusted on the front panel. The instantaneous states are indicated by LED`s. The current phase positions of the two networks in comparision to one another can be observed via the 0V display. Another function is fully automatic frequency acceleration after a standstill time of 5 sec. The SYFN30 is equipped with protective measures against wrong synchronization and also works reliably with all types of disturbances on the lines connected.

DFN300

Frequency control for generators / diesel generators
Mains-controlled setpoint frequency, quartz-controlled in case of mains failure
Available for 50Hz and 60Hz mains networks
Control impulses can be tapped via "Up" and "Down" contacts
Pulse-width adjustable from 0.1 - 1 sec

DFN300 231/400V 50Hz

This unit is used for the fine adjustment of the generator frequency. For the purposes of parallel connection of a generator with the mains, if a voltage is present continuous control is carried out with the output pulses.If the frequency difference is larger, correspondingly more control pulses are output in order to bring the generator close to the setpoint value rapidly. If synchronization is carried out and the generator remains suspended between the zero points of the generator and mains frequency, a short "Up" pulse is given after 5 sec in order to initiate control. In case of power failure, the unit automatically switches over to the internal quartz-controlled setpoint value.

DSP300 231/400V 50Hz

This unit is used for manual synchronization or for monitoring synchronization as an additional safeguard against wrong synchronization. Release is effected by closing of contacts 17-18. The unit works in both directions. The +/- phase range within which the output contact is closed is set via the phase adjuster.
