Phase Balancer PB50A-3P-200ADV - phase balancing device for 0.4 kV networks, 50 A
Country: Finland · Model: Phase Balancer PB50A-3P-200ADV
The Phase Balancer PB50A-3P-200ADV is a three-phase device for equalizing phase unbalance in 0.4 kV networks (230/400 V) with a rated current of 50 A. It is connected in parallel to the line, so it suits weak overhead networks where load imbalance must be removed without rebuilding the line.

Description
The parallel-connected device equalizes phase unbalance, reduces flicker and harmonics and increases the line capacity without reconstructing it. It is oil-free, so it needs no oil system maintenance and is suitable for installation directly on a pole. The enclosure has an IP55 degree of protection, so dust and water jets from any side do not put the electronics out of action. Dimensions of 435×785×430 mm at a weight of 125 kg are within the capacity of a pole and two installers with a lifting device. For integration into a dispatching system, Modbus RTU communication via RS-232 is provided, and operating modes can be read from a remote point. Electromagnetic compatibility and harmonic emission of the device have been checked per EN 61000-3-2, -3-3, -6-2 and -6-3, and the enclosure design complies with EN 61439.
How to choose
The main parameter here is the rated current of 50 A, and it is compared with the size of the current imbalance at the most loaded point of the line, not with the transformer power. The network must be three-phase 230/400 V, and this version does not support other voltages. If the problem is not unbalance but a sag or rise of voltage on a single-phase branch, see the voltage regulator VC6K-1P-000 for 230 V and 25 A. It corrects the voltage in the range of -10...+15% and has a degree of protection of IP54, dimensions of 400×600×350 mm and a weight of 30 kg.

FAQ
Which networks is the Phase Balancer PB50A-3P-200ADV intended for?
For weak three-phase 0.4 kV, 230/400 V networks with phase imbalance, flicker or harmonics. The device is connected in parallel and does not require reconstruction of the line.
Can it be installed outdoors on a pole?
Yes, the device is oil-free and is mounted on a pole. The enclosure has an IP55 degree of protection and dimensions of 435×785×430 mm at a weight of 125 kg.
What is the rated current of the device?
50 A. This current should be compared with the expected imbalance of phase currents at a specific point of the network.
How is the balancing device connected to a dispatching system?
Through the Modbus RTU (RS-232) interface. This makes it possible to build it into an existing data acquisition system.
How does this device differ from the VC6K-1P-000 regulator?
The Phase Balancer works in a three-phase 230/400 V network at 50 A and equalizes the phases. The VC6K-1P-000 is intended for a single-phase 230 V, 25 A network and corrects the voltage level.
