Static converters for railway vehicle power supply systems

POLL is a manufacturer of static converters and central energy sources (CES) for on-board railway vehicle networks.

A large part of our company's portfolio consists of static converters, which are used to power on-board vehicle networks, recharge vehicle batteries and power 1f and 3f devices. Our products achieve interesting parameters by numerical control of inverters, the use of computer models in development and the use of new technologies.
