Detailed Technical Specifications

Electrical Specifications – Input

• Input Voltage Range: 85 – 264 VAC
• Input Frequency Range: 47 – 63 Hz
• Input Current: 2.0A max @ 100VAC; 1.0A max @ 240VAC
• Inrush Current: 40A max for 5ms @ 120VAC; 60A max for 5ms @ 240VAC
• Hold-up Time: 20 ms minimum (allows the system to ride through brief power interruptions)
• Input Protection: Internal fuse and EMI filtering.

Electrical Specifications – Output

• Total Output Power: 100 Watts (This is a key identifier for this model)
• +5.1VDC Output: 7.0A max (This is the main logic power for the backplane and modules)
• +24VDC Output: 2.5A max (This is used to power the internal electronics of certain I/O modules and is often labeled as “Field Power” or “Sensor Power”)
• Ripple and Noise: <50mV peak-to-peak on the +5.1V output; <100mV peak-to-peak on the +24V output.
• Line Regulation: ±1%
• Load Regulation: ±1%
• Overvoltage Protection (OVP): Yes, on both output rails.
• Overcurrent Protection (OCP): Yes, on both output rails. The power supply will shut down and automatically attempt to restart.

Mechanical & Environmental Specifications

• Form Factor: A single-slot module designed for the 90-30 or RX3i series baseplate/rack.
• Dimensions (H x W x D): Approximately 3.23 x 5.12 x 4.33 inches (82 x 130 x 110 mm)
• Weight: Approximately 1.2 lbs (0.54 kg)
• Operating Temperature: 0° to 60° C (32° to 140° F)
• Storage Temperature: -40° to 85° C (-40° to 185° F)
• Relative Humidity: 5% to 95% (non-condensing)
• Cooling: Convection cooled (no internal fan). Requires proper spacing and ventilation in the chassis.
• Safety Certifications: UL Listed, cUL Listed, CE Marked. Designed to meet UL 508 and IEC 61131-2 standards.

Status Indicators (LEDs)

The module features two LEDs for diagnostics:

• PWR (Green): Illuminates when input power is present and the outputs are within normal range.
• FAULT (Red): Illuminates if an output overvoltage or overcurrent condition is detected.
