Description

30-Second Fit Check

Output rail: 60V DC at 20A (1200W)
Output trim: adjustable 54–66V for setpoint tuning
Peak capability: series peak power spec listed as 3800W/5s (input ≥180VAC)
Input: single-phase 90–264VAC (47–63Hz)
Controls/comms: DC_OK + remote sense + remote on/off; PMBus/CANBus optional

What It Is & Why It Matters

1200W platform with monitoring hooks so integration teams can build “power health” into the system
Remote sense supports tighter voltage control at the load when wiring resistance is non-trivial
Optional PMBus/CANBus helps projects that want a path to telemetry/control (confirm ordering options)
Active current sharing supports designs that distribute load across units (system design dependent)

Key Specs

Rated output: 60V, 20A (1200W)
Peak power (series): 3800W for 5s when input ≥180VAC
Output quality (series): ripple 1% p‑p; dynamic response <5%; regulation <3%
Aux rail (series): 5V / 2A max
Mechanical (series): compact dimensions are listed in the datasheet

Integration & Controls

DC_OK analog indication signal
Remote sampling / remote sense compensation
Remote on/off control
PMBus or CANBus options
Series lists operation up to 5000m altitude

Best for / Not for

Best for: 60V rails needing a broad 54–66V trim range and DC_OK monitoring
Best for: builds planning for optional PMBus/CANBus integration
Not for: applications that must be fanless (fan speed control is listed for the series)
Not for: systems requiring input below 90VAC or peak use outside the datasheet input condition

Typical Applications & Selection Checklist

Applications (listed/implied): industrial/medical AC/DC systems; collaborative robotics subsystems
Setpoint check: confirm target voltage fits 54–66V
Monitoring check: decide how you’ll use DC_OK (controller input, alarm, service routine)
Comms check: if PMBus/CANBus is required, confirm the correct ordering option
Thermal check: validate airflow and cabinet temperature during verification testing
