ВД2M Type Rectifiers for Power Supply of Metro Contact Networks

VD2M-1600-825 UHL4	For the metro with 10-12 cars in the train
VD2M-1600-825-1 UHL4	For the metro with 4-5 cars in the train

Climatic version of the rectifier - UHL for macroclimatic areas with a temperate and cold climate, placement category 4 according to GOST 15150-69 and GOST 15543.1-89.
The rectifier is designed to work when installed at a height of no more than 1000 m above sea level, the working value of the ambient air temperature is from + 1 to + 35 C and relative humidity of 60% at 20 C. Limit operating values of ambient air temperature from + 1 to + 40 C and relative humidity of air 80% at 25 C.
Rectifier VD2M has a microprocessor control, protection and alarm system (based on Siemens), which allows you to adapt this device to the automated control system of the traction substation complex.
