Installation Manual 2. Physical Description
2.9 Power Supply
The device can be powered from one of the following power sources (depending on
customer order):
„ AC power source (refer to ''AC Power System'' on page 37 )
„ DC power source (refer to ''DC Power System'' on page 41 )
Notes:
•
Currently, the AC power option is supported only by Mediant 3000.
•
To change the Mediant 3000's power system (i.e., AC to DC, or DC to
AC), you need to change your chassis. Please contact AudioCodes for
further information.
„ DC input range:
•
The device is designed to be powered from -48 VDC grounded DC power
systems
•
Reverse-polarity protected
„ AC input:
•
Universal 100 to 240 VAC input
•
Power factor correction (AC input)
„ Active current load sharing on positive outputs (V1, V2 )
„ Integral LED status indicators
„ Hot-pluggable connector, with staged pin lengths
„ Hot swappable
„ Optimized thermal management
„ Control and monitoring features
Power for the device is provided from either AC or DC redundant power feeds, where AC
input voltage ranges from 100 to 240 VAC, 50/60 Hz and DC input voltage ranges from -
40.5 to -60 VDC. The power entry modules are PEM/AC/3K or PEM/DC/3K for AC and DC
respectively. Power supply units function in a load-sharing configuration to provide
necessary voltages and fail-safe operation.
The PS/AC/3K or PS/DC/3K power supply modules are multi-output switching power
supplies, provided in AC or DC primary input power configurations respectively. LEDs
indicate power and fault status. The AC or DC power supply comes in an ultra-compact
design measuring 4 x 12.7 x 28 cm (1.6 x 5 x 11 inch), for a 6.8 watt/inch3 power density
output. The unit has a handle for easy removal and re-insertion, under power (hot-swap
capable).
