PFS1500T28

30-Second Fit Check

• Output rail: 28V DC at 53.6A (1500W)
• Setpoint window: adjustable 26–28V (verify your load tolerance)
• Current budget: verify continuous load and wiring drop—remote sense can help at the load point.
• Input: single-phase 90–264VAC (47–63Hz)
• Controls: DC_OK status + remote sense + remote on/off; PMBus
• Medical/industrial readiness: 2×MOPP isolation + safety approvals (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 (Evidence)

• Rated output: 28V, 53.6A (1500W)
• Input range: 90–264VAC (47–63Hz)
• Efficiency (series note): Series lists 93.5% max for 12–24V variants and 94% max for 48–100V variants (excluding fan loss)—see datasheet
• 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
• Remote control: remote on/off control
• Current sharing: active current sharing support
• Comms: PMBus
• Aux rail: 5V / 2A max

Best For / Not For

• Best for: programs that need a 1500W supply with industrial + medical safety approvals .
• 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 is ).

Typical Applications

• Collaborative robots and automation subsystems
• Industrial equipment power rails
• Cooling systems (cabinet environments)
• Medical equipment power architectures (IEC/UL 60601-1 )
• 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.
