30-Second Fit Check

• Output rail: 12V DC at 125A (1500W)
• Setpoint window: adjustable 12–12.5V (verify your load tolerance)
• High-current rail: plan distribution hardware (busbars/terminals/cables) for continuous current and heat rise.
• Input: single-phase 90–264VAC (47–63Hz listed)
• Controls: DC_OK status + remote sense + remote on/off; PMBus listed
• Medical/industrial readiness: 2×MOPP isolation + safety approvals listed (see datasheet)

What It Is & Why It Matters

• 1500W AC/DC platform for industrial and medical power architectures that want a compact footprint and clear integration signals.
• DC_OK + PMBus provides a path to status monitoring and power-health visibility in automated systems.
• Remote sense helps compensate voltage drop across high-current cabling so the load sees closer-to-target voltage.
• Active current sharing supports parallel designs where load distribution is required (system design dependent).

Key Specs

• Rated output: 12V, 125A (1500W)
• Input range: 90–264VAC (47–63Hz)
• Efficiency (series note): 93.5% max for 12–24V models (excluding fan loss)
• Isolation: Primary-to-secondary: 4000VAC; primary-to-earth: 1500VAC; secondary-to-earth: 1500VAC
• Leakage current: Touch leakage <100µA; earth leakage <300µA

Use the datasheet limits and validate performance in your end system—especially wiring drop, airflow, and compliance testing.

Integration & Controls

• DC_OK: analog indication signal
• Remote sense: remote sampling / sense compensation (listed)
• Remote control: remote on/off control (listed)
• Current sharing: active current sharing support (listed)
• Comms: PMBus listed
• Aux rail: 5V / 2A max (listed)

Best For / Not For

• Best for: programs that need a 1500W supply with industrial + medical safety approvals listed.
• Best for: integration-heavy systems that benefit from DC_OK monitoring and remote control features.
• Not for: mains below 90VAC input range.
• Not for: fanless-only builds (smart fan speed control).

Typical Applications

• Cooling systems and cabinet power architectures
• Industrial equipment power rails (controls + high-current loads)
• Medical equipment power systems (IEC/UL 60601-1)
• Collaborative robots and automation subsystems
• Robot vacuum / cleaning equipment charging modules
• Stage lighting power systems

Selection Checklist

• Confirm your required voltage fits the trim range and validate at the load point (after wiring drop).
• Size conductors and distribution for continuous current (especially on 12–24V high-current rails).
• Decide whether you will use DC_OK as a controller input, alarm, or service indicator.
• If PMBus telemetry is required, confirm the interface/connector details for your exact model.
• Plan airflow—this series lists smart fan speed control; verify cabinet temperature in test.
• Verify installation altitude and compliance testing requirements early in your program.
