DESCRIPTION
The RM24150 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
These shelf-mounted modules are easy and safe to install
or remove while system is operational without affecting
the overall system’s performance.
Parallel Operation and Automatic Load Sharing
Forced or passive load sharing is available between
modules of the same operating voltages in parallel
applications.
Alarm Outputs
Rectifier Fail Alarm (RFA)
Thermal Shutdown Occurring (THSD)
Open Sense Lead Has Occurred (OS)
AC Power Has Failed Alarm (ACF)

Note: All alarms are “Form A” relay type contacts
Current Limit
The Current Limit is adjustable between 0A to 150A. Upon
exceeding this limit, the rectifier automatically reduces
output voltage.

PROTECTION, ALARM AND CONTROL SYSTEMS
Rectifier Failure Alarm (RFA)
Problems occurring because of an unacceptable relationship between the output power and load conditions will
cause a Rectifier Failure Alarm (RFA). This alarm consists
of a red LED and a flashing green OK LED. Conditions
which may lead to an RFA are:
Low Current - Output current has decreased to below
5% of its rated value.
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.
High Voltage Shutdown (HVSD)
The unit’s high voltage limit is adjustable up to 30VDC.
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
6000V/3000A.
Under Voltage Protection
When input voltage is below 183 VAC, the rectifier’s
operation is automatically inhibited.
