1 Principles of Operation Introduction The RM2048HE is a telecommunications grade rectifier with the following features: High Efficiency Hot Pluggable Forced Air Cooled Thermally Protected Power Factor Corrected Wide input AC Voltage Constant Power Output Limit ... -
Page 4: Output Over-Voltage Shut Down
Serial Alarm and Control Interface The rectifier, when installed in an Newmar rectifier shelf or system, is controlled via the serial interface by the system monitor. The system monitor can set up control parameters and receive alarm information via this interface. -
Page 5: Voltage Control
1.11.1 Voltage Control The rectifier voltages are set by the system monitor via the serial communications bus. The rectifier voltage can be set to any value between 43V and 60V. The monitor operates in several modes that will affect the rectifier voltage setting. -
Page 6: Post-Mate Connection
1.12 Post-mate Connection The rectifier is “hot plug” capable. This is achieved by having one pin on the rear connector that mates after the other pins. This pin must be connected to negative bus volts and the rectifier will not start until this pin engages. If a rectifier will not start, ensure the rectifier is fully engaged in the Goldfish connector in the rectifier shelf. -
Page 7: Rectifier Shelf
The rectifier contains components at High Temperatures that may burn if touched Rectifier Shelf The RM2048HE rectifier must only be used in conjunction with an appropriate Newmar designed or Newmar approved system or rectifier shelf. AC Supply Surge Protection The AC supply that feeds the rectifiers must have surge protection installed to meet levels defined for terminal equipment. -
