Description

30-Second Fit Check

Output: 100V DC, 12A (1200W)
Trim range: 90–110V
Peak current: 38A peak listed for this model
Input: 90–264VAC (47–63Hz)
Controls: DC_OK + remote sense + remote on/off; PMBus/CANBus optional

What It Is & Why It Matters

100V rail targeting with a 90–110V adjustment window for commissioning alignment
Remote sense supports better regulation at the load point under wiring resistance
DC_OK helps ops teams detect “power healthy” vs “power fault” faster
5V/2A auxiliary rail can support control-side needs where applicable (series spec)

Key Specs

100V / 12A rated output
Series peak: 3800W for 5s when input ≥180VAC
Ripple 1% p‑p; dynamic response <5%; regulation <3% (series)
Altitude up to 5000m listed (series)
Aux: 5V/2A max (series)

Integration & Controls

DC_OK analog indication signal
Remote sense compensation + remote on/off
PMBus/CANBus optional (confirm ordering)
Smart fan speed control listed—plan cabinet airflow and verify in test

Best for / Not for

Best for: systems requiring a 100V DC rail with a usable 90–110V trim range
Best for: integration-driven builds using DC_OK and remote sense
Not for: fanless-only designs
Not for: installations needing input below 90VAC

Typical Applications & Selection Checklist

Applications: industrial/medical AC/DC systems; collaborative robotics power subsystems
Confirm target voltage fits 90–110V
Validate peak events vs 38A peak and series peak condition
Decide if optional PMBus/CANBus is required for your program
Verify thermal performance during end-product verification testing
