Description

30-Second Fit Check

Output class: 24VDC, 42A (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.
Trim range: ±5% adjustable output.
Terminal style (listed): 24V model uses 2P M5 copper screw output terminals; input terminal 3P-8.25.

What It Is + Why It Matters

High-power, open-frame AC-DC SMPS for 24V systems needing ~1kW output capability.
Active PFC and universal input are listed—useful for deployments across 120V/208V/240V facilities.
Protection behavior is clearly defined (hiccup overload; lock-style short/over-voltage with power-off reset time).
Compact 214×82×48mm size can simplify integration when space is limited for a 1kW class supply.

Key Specs (Evidence)

Rated output: 24V, 42A; 1008W.
Ripple & noise: 300mVp-p.
Accuracy/regulation: output accuracy ±1%; line ±0.5%; load ±0.5%.
Input current (listed): 5A @230VAC; 11A @110VAC.
Inrush current: cold start 60A @230VAC.
Leakage current: <0.75mA @240V.
Timing (listed): 500ms/30ms/5ms @115VAC; 300ms/30ms/10ms @230VAC (setup/rise/hold).
Mechanical: 214×82×48mm; 1.2kg; MTBF >50k hrs (MIL-HDBK-217F, 25°C) listed.
Operating environment: -20 to 60°C; 10–90% RH (non-condensing).

Integration & Controls

Terminals (listed): input terminal 3P-8.25; output terminal 2P M5 copper screw (12V/24V/28V models).
Brown-out behavior: input under-voltage protection ≤70VAC, auto recovery (listed).
Recovery expectation: short-circuit and over-voltage protections are lock-style and require power-off time to restore (see Protections card).
Thermal: shell over-temperature behavior is listed; still validate airflow and spacing in your enclosure.

Best For / Not For

Best for: 24V industrial automation rails, motion control subsystems, PLC/distribution panels needing up to ~1kW.
Not for: systems that cannot tolerate lock-style shutdown on short/OVP events (requires power-off time to restore).
Not for: installations requiring sealed/IP-rated housings without additional enclosure design.

Typical Applications

Industrial automation and control cabinets
Motion control and equipment subsystems
PLC/DC distribution panels
High-power 24V equipment rails

Selection Checklist

Confirm output need: 24V / 42A and peak headroom.
Confirm upstream circuit capacity (input current + inrush are listed).
Confirm acceptable ripple: 300mVp-p.
Confirm terminal preference: 2P M5 output terminal style for this voltage class (listed).
Confirm ops expectations for lock-style recovery after short/OVP events.
Plan airflow/clearance for open-frame installation.

RFQ Quick Checklist: quantity, target delivery, mains voltage, load profile (steady/peak), terminal/wire constraints, enclosure airflow notes, required documentation.
Note: final compliance and performance depend on end-product design and verification testing.
