Description

30-Second Fit Check

Output: 85V DC, 14.2A (1200W)
Trim range: 80–90V
Peak current: 44.7A peak
Input: 90–264VAC global input range (47–63Hz listed)
Controls: DC_OK + remote sense + remote on/off; PMBus/CANBus optional

What It Is & Why It Matters

85V rail support with an 80–90V trim window for setpoint alignment
Remote sense helps keep the delivered voltage closer to target under load
Active current sharing supports load distribution in parallel architectures
Series lists 5000m altitude operation for high-elevation installations

Key Specs (Evidence)

85V / 14.2A rated output
Series peak power: 3800W for 5s when input ≥180VAC
Output quality (series): ripple 1% p‑p; dynamic response <5%; regulation <3%
Aux: 5V/2A max (series)
Smart fan speed control (series)

Integration & Controls

DC_OK analog indication signal
Remote on/off + remote sense compensation
PMBus/CANBus optional (confirm ordering)
Plan airflow and verify thermal conditions during system testing

Best for / Not for

Best for: equipment built around an 85V rail that needs a trim window (80–90V)
Best for: designs that benefit from DC_OK monitoring and remote sense
Not for: fanless-only requirements
Not for: operation below 90VAC input

Typical Applications & Selection Checklist

Applications: industrial/medical AC/DC systems; collaborative robotics subsystems
Confirm your setpoint fits 80–90V
Validate peak events vs 44.7A peak current and the series peak condition
Decide whether current sharing is required for your architecture
Verify installation airflow and ambient during verification testing
