Inverter  PSB is intended for supply direct current consumers (voltage 28 V) in municipal electric transport stock. It is constant-voltage power supply with the maximum current  limiting. Its output characteristic make possible the synchronous supply of on-board consumers and battery charging. Control range and given accuracy of effective value make possible normal operation with alkaline (Ni-Cd or Ni-Fe) or unattended (hermetic) acid accumulator.
