The RM4830 Modular Switched-Mode Rectifier is one of
C&D Technologies’family of rectifiers that may be used in
modular power plants. This unit will function in parallel
with any rectifier with similar current sharing capacities.
This compact, versatile and efficient unit is ideal for use in
small to medium cellular and PCS sites.

GENERAL FEATURES
Hot Swappable Modules
Current Limit
When rectifier current reaches 30ADC - 32ADC, the unit
will automatically limit the current down to short circuit con-
ditions with no fold back.
These shelf-mounted modules are easy and safe to install
or remove while system is operational without affecting
the overall system’s performance.
LED Indicators
Parallel Operation and Automatic Load Sharing
A series of RM4830 rectifiers will automatically share equal
amounts of the load current when operating in parallel
within 5% of the average current for the load applied.
The front panel includes a 10 segment yellow LED output
current bar graph, a green normal operation LED, and a
red rectifier failed LED.
Safety
N+1 Operation
UL/CUL Recognized: UL 1950/CSA 950.
File No.: E131694
The rectifier can operate in true N + 1 redundacy mode.
EMI filtering to FCC and VDE-0875 limits.
Remote Equalize
The rectifier output may be changed from float to equalize
via remote signal.

PROTECTION, ALARM AND CONTROL SYSTEMS
Rectifier Failure Alarm (RFA)
High Voltage Shutdown (HVSD)
Problems occurring because of an unacceptable relation-
ship between the output power and load conditions will
cause a Rectifier Failure Alarm (RFA).This alarm consists
of a red LED. Conditions which may lead to an RFA are:
Low Current - Output current has decreased to below
2% of its rated value.
The unit’s built-in high voltage limit is permanently set at
60.5VDC. When internal shutdown occurs, the unit may
be restarted by a local switch or by a remote signal.
Surge Protection
The unit will withstand lightning and input surges of
Unit Shutdown - Any shutdown occurrence due to
overvoltage, external shutdown command, unacceptable
ambient temperature conditions or low AC input voltage.
Fan Malfunction - The fan has stopped operating or is
not providing the airflow needed to cool the unit.
Over Temperature - The ambient temperature has
exceeded 50°C.
6000V/3000A.
Under Voltage Protection
When input voltage is below 106 VAC (with tolerance),
the rectifier’s operation is automatically inhibited.
Output Circuit Protection Device (Fuse)
The unit has one internal output protection fuse which is
in series with the -48VDC output.
