OPR300-24S / OPR300-24R
2.1 OPR300-24S / OPR300-24R Description:
The Models OPR300-24S and OPR300-24R are 1U rack mountable power supplies designed to
operate in single and redundant power configurations respectively. OPR300-24S has one built-in
universal AC to 24V DC power supply, and OPR300-24R has two built-in universal AC to 24V
DC power supplies with two IEC AC sockets for complete redundancy. OPR300-24S provides
up to 300W of power, and OPR300-24R provides up to 600W of redundant power
*
to the system
that each is attached. Each model has its own AC-INLET (one for OPR300-24S and two for
OPR300-24R), ON/OFF switches, and power LEDs (one for OPR300-24S and two for
OPR300-24R). Both models have two built-in alarm circuits with red LEDs for low DC power
monitoring and for remote power management.
