The RM4850 Modular Switch-Mode Rectifier is one of C&D
Technologies’family of rectifiers that may be used in modular
power plants. This high power unit will function in parallel
with any rectifier with similar current sharing capacities. This
versatile and efficient rectifier is ideal for use in advanced
telecommunications applications. Its small size allows the
user to plan economically for system expansion at minimum
cost and makes it ideal for use in fiber optic, microwave
and other applications where space is at a premium.

GENERAL FEATURES
Hot Swappable Modules
Current Limit
The Current Limit is adjustable between 0A to 50A. Upon
exceeding this limit, the rectifier automatically reduces
output voltage.
These shelf-mounted modules are easy and safe to install
or remove while system is operational without affecting
the overall system’s performance.
Safety
Parallel Operation and Automatic Load Sharing
Forced or passive load sharing is available between
modules of the same operating voltages in parallel
applications.
UL/CUL Recognized: UL 1950/CSA 950.
File Number: E181908

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). Conditions which
may lead to an RFA include:
Low Current - Output current has decreased to below
5% of its rated value.
The unit’s high voltage limit is adjustable up to 60VDC.
Shutdown occurs while voltage is high and the rectifier is
delivering greater than 10% rated current. When internal
shutdown occurs, the unit may be restarted by a local
switch or by a remote signal.
Unit Shutdown - Any shutdown occurrence due to
overvoltage, external shutdown command, unacceptable
ambient temperature conditions or out of bounds AC input
voltage.
Surge Protection
The unit will withstand lightning and input surges of
6000V/3000A.
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 65°C.
Under Voltage Protection
When input voltage is below 176 VAC, the rectifier’s
operation is automatically inhibited.
