3500/15 AC and DC Power Supplies

The 3500/15 Power Supply is a half-height module. It must be installed in the designated slots on the left side of the rack. The 3500 rack can hold one or two power supplies, with any combination of AC and DC power. Either supply can power a full rack.

If two power supplies are installed, the lower slot supply acts as the primary, and the upper slot supply serves as the backup. Removing or inserting a power supply module does not disrupt rack operation if a second power supply is installed. The 3500/15 Power Supply accepts a wide range of input voltages and converts them to voltages suitable for other 3500 modules.

Available power supply options for the 3500 Series Machinery Protection System:

• Legacy AC Power
• Universal AC Power
• High Voltage DC Power Supply
• Low Voltage DC Power Supply

Specifications

Inputs

All Power Supply Versions

• Out of Range Protection: Undervoltage will not harm the supply or PIM. Overvoltage will cause the fuse on the PIM to open.
• Maximum Input Power:
  • Maximum output power / Minimum efficiency
  • Maximum Volt-Amps
  • Maximum input power / Minimum power factor

Low Voltage AC

• Input Voltage: 85 to 132 Vac rms (120 to 188 Vac peak)
  • For installations with older AC Power Input Modules (PIMs) or AC Power Supply Modules, a voltage of 85 to 125 Vac rms is required.
• Frequency: 47 to 63 Hz
• Input Current: 4.5 A rms maximum
• Input Power: 194 W maximum
• Efficiency: 0.8 minimum, typical
• Power Factor: 0.5 minimum, typical
• Volt-Amps: 388 VA, maximum

High Voltage AC

• Input Voltage: 175 to 264 Vac rms (247 to 373 Vac peak)
  • For older installations, a voltage of 175 to 250 Vac rms is needed.
• Frequency: 47 to 63 Hz
• Input Current: 2.3 A rms maximum
• Input Power: 194 W maximum
• Efficiency: 0.8 minimum, typical
• Power Factor: 0.5 minimum, typical
• Volt-Amps: 388 VA, maximum

Low Voltage DC

• Input Voltage: 20-30 Vdc
• Input Current: 10 A maximum
• Input Power: 194 W maximum
• Efficiency: 0.8 minimum, typical

High Voltage DC

• Input Voltage: 88-140 Vdc
