Description

30-Second Fit Check

Output: 72V DC at 16.7A (1200W)
Trim range: 65–79V (setpoint flexibility for 72V rails)
Peak current: 52.8A peak is listed for this variant
Input: 90–264VAC (47–63Hz)
Controls: DC_OK + remote sense + remote on/off; PMBus/CANBus optional

What It Is & Why It Matters

Wide trim window helps match the real setpoint your system needs (within your device tolerances)
DC_OK supports serviceability—power health can be surfaced to a controller or alarm logic
5000m altitude operation is listed for the KFS1200 series (useful for high-elevation deployments)
Active current sharing supports parallel designs where load distribution is required

Key Specs

Rated output: 72V, 16.7A (1200W)
Peak power (series): 3800W for 5s when input ≥180VAC
Output quality (series): ripple 1% p‑p; dynamic response <5%; regulation <3%
Aux: 5V/2A max (series)
Altitude: up to 5000m (series)

Integration & Controls

Remote sense (remote sampling) + remote on/off control
DC_OK analog indication signal
Optional PMBus/CANBus (confirm ordering)
Smart fan speed control listed

Best for / Not for

Best for: systems built around a 72V DC rail that need trim flexibility (65–79V)
Best for: applications where DC_OK helps reduce troubleshooting time
Not for: fanless-only designs
Not for: input below 90VAC or peak operation outside the ≥180VAC peak condition

Typical Applications & Selection Checklist

Applications: industrial/medical AC/DC systems; collaborative robots power subsystems
Confirm required setpoint fits 65–79V
Validate peak events vs listed peak current and the series peak condition
Decide whether remote sense wiring is needed for your harness length
Verify cabinet cooling and run verification testing at worst-case ambient
