Description

30-Second Fit Check

Output class: 28VDC, 36A (1008W).
AC input: 90–264VAC (rated input voltage listed 100–240VAC), 50–60Hz.
Efficiency: 93% @230VAC (listed).
Active PFC: PF listed >0.98 @100V and >0.95 @230V.
Ripple & noise: 300mVp-p.
Terminal style (listed): 28V model uses 2P M5 copper screw output terminals; input terminal 3P-8.25.

What It Is + Why It Matters

1kW-class SMPS for equipment that standardizes on a 28V rail and needs high current.
Universal input and active PFC are listed—helpful for mixed facility mains.
Defined recovery behavior can reduce integration surprises during commissioning (lock-style short/OVP requires power-off reset time).
±5% trim supports controlled setpoint adjustment for system tuning.

Best For / Not For

Best for: 28V industrial rails, equipment subsystems needing up to 36A output current.
Not for: systems needing continuous operation without manual power cycling after protection events.
Not for: sealed installs without additional enclosure/thermal engineering.

Typical Applications

Industrial control and automation equipment
High-power equipment-level DC rails
Distribution panels and test stations
Systems requiring universal AC input support

Selection Checklist

Confirm load envelope: 28V / 36A with headroom.
Confirm upstream power: mains range and circuit capacity (input current + inrush listed).
Confirm acceptable ripple: 300mVp-p.
Confirm terminal style: 2P M5 output screws for this model.
Confirm ops tolerance for lock-style recovery after short/OVP events.
Plan airflow/clearance for open-frame integration.

RFQ Quick Checklist: qty, target ship date, mains voltage, load profile, terminal/wire constraints, enclosure airflow notes.
Note: final compliance and performance depend on end-product design and verification testing.
