Phase Angle Switching (MiniPWZ)
Product description
The MiniPWZ II is specially designed for applications at power producers (for example in wind power) or for testing on-load tap changers. With the MiniPWZ II, switching operations can take place at a precisely adjustable phase angle. Either the mains frequency (50 Hz) or any sinusoidal AC voltage can be used as the reference signal.
Channels and configuration
The MiniPWZ II offers up to 9 digital inputs and 9 digital outputs (standard: 0/24 VDC, adjustable for example to 0/5 VDC). Most of the functionality is configurable via the firmware. By default – as described above – 4 inputs and outputs are used for phase-synchronous switching. The remaining inputs can be used, for example, for enable signals, while the other outputs can signal errors. The switch-on and switch-off angles and the respective operating modes can be configured individually via the integrated web server.
How it works
In the example, switching takes place at an angle of 90°. The input signal (pink) can be activated at any time – for example by a PLC. The output signal (blue) is then activated only when the 90° angle is reached (the yellow signal is the reference signal). In this operating mode, the output signal is deactivated again depending on the input signal; alternatively, it can also be deactivated at a specific phase position.
