Performance and Scale

• Maximum output power: 5700 W per module
• Output voltage: -48 V DC nominal (-40.5 V DC to -57 V DC range)
• Output current: 120 A maximum
• Efficiency: 92% at 30% to 100% load (per ENERGY STAR requirements)
• Hold-up time: 16 ms minimum at full load
• Inrush current: 50 A maximum at 230 VAC, 25°C

Interface Configuration

• AC input connectors: (2) IEC 60320 C20 three-wire AC power cords (16 AWG, 250 VAC, 15 A minimum rating)
• DC output: Internal bus bars to chassis midplane (no external ports)
• Input voltage range: 200 VAC to 240 VAC (high-voltage variant)
• Input frequency: 50 Hz to 60 Hz
• Grounding: Chassis ground via PEM frame

Physical and Environmental

• Dimensions (H x W x D): 1.75 in. x 17.5 in. x 15.0 in. (4.4 cm x 44.5 cm x 38.1 cm)
• Weight: 22 lb (10 kg) maximum
• Operating temperature: 0°C to 40°C (32°F to 104°F)
• Storage temperature: -40°C to 70°C (-40°F to 158°F)
• Humidity: 5% to 90% noncondensing
• Cooling: Front-to-back airflow; integrated fans not included (relies on chassis fans)
• Power consumption: 6000 VA maximum input at full load
• MTBF: 200,000 hours at 40°C (per Telcordia SR-332 Issue 3)

Configurable Options/SKU Differences

• Voltage variants: HV (200-240 VAC); companion LV (100-120 VAC) model MX2K-PSM-LV-R available
• Redundancy modes: -R suffix denotes hot-pluggable redundant PEM; non-R variant (MX2K-PSM-HV) for non-redundant setups
• Power cord options: Region-specific cords (e.g., NEMA L6-20P for North America, IEC 60320 C20 for international)
• No software licensing required; firmware updates via chassis management (Junos OS)

Use Cases

• Redundant power delivery in MX2000 router deployments for service provider core routing
• High-availability AC power in data center aggregation layers with 100G/400G interfaces
• Inline power protection for EVPN-VXLAN fabrics supporting up to 80 Tbps switching capacity
