Description

30-Second Fit Check

Output: 150V DC, 8A (1200W)
Trim range: 132–150V (narrower window—verify your exact setpoint)
Peak current: 25.3A peak
Input: 90–264VAC (47–63Hz)
Controls: DC_OK + remote sense + remote on/off; PMBus/CANBus optional

What It Is & Why It Matters

150V rail targeting with a defined adjustment window to reduce commissioning ambiguity
Remote control features (remote on/off + DC_OK) support integration and service workflows
Series isolation/leakage specs are explicitly stated—useful for high-voltage risk review
Active current sharing supports parallel architectures where load distribution is required

Key Specs

150V / 8A rated output
Series peak: 3800W for 5s when input ≥180VAC
Isolation (series): primary-secondary 3000VAC; primary-earth 1500VAC; secondary-earth 1500VAC
Leakage (series): touch <100µA; earth <500µA
Aux: 5V/2A max (series)

Integration & Controls

DC_OK analog indication
Remote sense compensation + remote on/off
Optional PMBus/CANBus (confirm ordering)
Smart fan speed control listed—plan airflow and validate during testing

Best for / Not for

Best for: systems needing a 150V rail where the required setpoint fits 132–150V
Best for: designs that want DC_OK visibility and remote on/off control
Not for: fanless-only requirements
Not for: projects needing a broader trim window than 132–150V

Typical Applications & Selection Checklist

Applications: industrial/medical AC/DC systems; collaborative robotics subsystems
Confirm setpoint fits 132–150V (and validate at the load point)
Validate peak events vs 25.3A peak and series peak condition
Confirm whether PMBus/CANBus is required and available for your ordering option
Run thermal verification testing at worst-case cabinet conditions
