Product Description
The HVE04.2-W075N/S202 is a power supply with 75 kilowatts nominal power rating. The supply belongs to HVE series from Bosch Rexroth. HVE family power supplies are designed for unregulated DC bus voltage operation which leads to variation in output power with variation in input voltage. Nominal input voltage range for which the HVE04.2-W075N/S202 is designed is 380 to 480 Volts AC. HVE supplies can sustain 200% of rated power for up to 30 seconds and 300% of rated power for up to 0.3 seconds. The continuous output power rating can be sustained by the supply for time durations exceeding 120 seconds. Weight of the power supply is 61.7 pounds. IP 10 rated housing of the supply measures 498 x 250 x 262 millimeters. The supply should be mounted inside an industrial cabinet where it will be protected from dust and moisture.
Three-phase input to the HVE04.2-W075N/S202 is rectified by the power rectifier of the HVE series supply. Motors with permanent magnets can be braked by the short-circuit bus when a malfunction occurs in the drive electronics. The HVE04.2-W075N/S202 includes an internal contactor which enables separation of drive controllers from the mains supply. The supply provides control voltages for the drive controllers which are connected to it. Due to integrated capacitors on the HVE04.2-W075N/S202, the energizing current does not need to be considered when choosing control units for the power supply. An alphanumeric display on the supply provides diagnostic information which can be used for troubleshooting. The HVE04.2-W075N/S202 comes with an internal blower. Optimal temperature range for power supply operation is 41 to 113 degrees Fahrenheit. Optimal relative humidity range for power supply operation is up to 95%.
