Description

30-Second Fit Check

Output class: 12VDC, rated 75A (900W).
Input: 90–264VAC (rated 100–240VAC), 50–60Hz.
Efficiency: 93% @230VAC listed.
Trim: ±5% output adjustable range.
Mechanical: 214×82×48mm; output terminals are 2P M5 copper screw for 12/24/28V models.

What It Is + Why It Matters

High-current 12V AC-DC SMPS for equipment that needs a single strong 12V rail.
Active PFC is listed (PF >0.98@100V, >0.95@230V), supporting cleaner interaction with facility power.
Protection behavior matters at this power level: short-circuit and OVP are listed as lock-style requiring power off time.

Key Specs

Rated output: 12V, 75A; 900W.
Ripple & noise: 200mVp-p.
Accuracy/regulation: accuracy ±1%; line ±0.5%; load ±0.5%.
Input current: 5A @230VAC; 11A @110VAC; inrush 60A @230VAC.
Leakage: <0.75mA @240V.
Environment: -20~60°C, 10~90%RH non-condensing.

Integration & Controls

Input terminals: 3P-8.25 listed.
Output terminals: 2P M5 copper screw terminal (12V model listing).
Timing: setup/rise/hold: 500ms/30ms/5ms @115VAC; 300ms/30ms/10ms @230VAC.
Brown-out: ≤70VAC listed with auto recovery.

Best For / Not For

Best for: high-current 12V industrial systems, large 12V DC rails with controlled wiring and protection expectations.
Not for: systems that cannot tolerate a lock-style shutdown on short/OVP events (requires power-off time to recover).

Typical Applications

12V industrial power systems
High-current 12V equipment rails
Factory automation subsystems using 12V distribution
Test stations requiring 900W-class 12V output

Selection Checklist

Confirm load envelope: 12V / 75A with peak headroom.
Confirm recovery behavior fits ops: short/OVP are listed as lock protection requiring power off time.
Check ripple tolerance: 200mVp-p.
Verify mains and upstream circuit capacity (input current listed at 110/230VAC).
Thermal planning: over-temp is listed; confirm enclosure airflow and mounting.

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

Reliability & Protections

Overload: 105–150% hiccup, automatic recovery.
Short circuit: lock protection; restore after turning off power for 5 minutes.
Over-voltage: Vout 120–140% lock; restore after power off for 5 minutes.
Over-temp: shell >115°C output off, automatic restore.
Safety/EMC standards (listed): GB4943, EN60950-1, EN62368-1; EMC includes EN55032 Class B, EN61000-3-2 (plus GB/T9254, GB17625.1).
