III — FEATURES
• Primary Output Adjustable ±10%
• 12 Volt Auxiliary Fan Output
• Power OK Output (suitable for external LED)
• Remote Error Sensing
• Overvoltage/Overcurrent protection
• Power Factor Corrected, Universal a-c input • Full 300 Watt Operation up to 50°C Ambient
• Convection cooling
• RoHS-Compliant
• 120% Power Capability with forced air cooling
(Operation of Model RMW 51212K-300 at peak
(maximum) power of 360W without cooling fan
must be limited to less than 60 seconds.)
IV — INSTALLATION
MOUNTING THE POWER SUPPLY. Refer to Figure
2. The unit may be mounted using 6-32 mounting screws
(not supplied). Eight mounting holes are provided: four on
the base, and two on each side. Note the restrictions for
maximum penetration of mounting screws (see Figure 2).
CONNECTIONS: All connections are made via TB1
through TB5 (see Figure 2 for locations).
NOTE: Parallel connection of RMW 300W units is not
supported.
AC input power is applied via terminal block TB1. Connect
the AC input Neutral, Line and Earth Ground wires to the
respective terminals of the terminal block (see Figure 2).
TB2 provides the DC outputs; see Table 2 for pin alloca-
tion.
TB3, TB4 and TB5 are each 2-pin connectors that require a
Molex 5045-02A (or equivalent) mating connector.
• TB3 provides a floating +12V output for use with
an auxiliary fan (not supplied).
• TB4 provides ± connections used for remote
sensing.
• TB5 provides connections used to drive an exter-
nal LED (not supplied).
REMOTE SENSING: TB4 provides +S and –S connec-
tions to be used for remote sensing. Figure 1 shows proper
connection of multiple loads using remote sensing. Remote
sensing compensation is up to 0.5V per load wire. Use
shielded (recommended) or twisted wire for remote sense
connections. Install one electrolytic capacitor (470
µF)
between +S and + and one between – and –S terminals.
