IP-5 is designed for electric power supply of lamp circuits and auxiliary equipment of mine trolley locomotives and converts DC voltage 250 V into stabilized constant voltage 24 V with load current 10 А.
IP-5 output is protected against short-circuit protection on the side of load. Coefficient of efficiency under nominal values of input voltage and load current of IP-5 is at least 80%.
The insulating strength ensures nonavailability of insulation breakdown and insulation breakover under test DC voltage 2100 V in normal operating conditions and 1500 V in raised humidity conditions during inspection between input and body, input and output of IP-5.
IP-5 is to be operated under conditions of gravity-type airflow. The operational position is vertical (cable entries downwards); deviations up to 5 degrees from the operational position to any side are permitted. Protection level is 1P54 under GOST 14254-96. Outside surface temperature of IP-5 while working at rated loading does not exceed 50 оС. The average error-free running time is at least 1000 h at the temperature of 25 оС. The average lifetime with account for repairing work is at least 10 years.
