4. Key Features

1. 100–150 VDC wide‑range input: for 125V DC industrial systems。

2. 8A high‑current 5.1 VDC output: for large/heavy‑load Quantum racks。

3. Redundant (1+1): two units for fault‑tolerant operation。

4. Summable (2 units max): parallel up to 16 A total。

5. Basic protection: OVP/OLP/SCP/thermal shutdown。

6. Green “PWR OK” LED: local status only (no alarm relay)。

7. Hot‑swappable: replace without rack shutdown。

8. Non‑coated (standard): for general industrial environments。

5. Certifications

6. Ordering Notes

• 140CPS52400: 100–150 VDC, 8 A redundant/summable, non‑coated, no alarm contact。

• Compare to 140CPS52400C: 52400 = non‑coated; 52400C = conformal coated。

• Compare to 140CPS51100/51100C: 52400 = 8A redundant; 51100 = 3A non‑redundant。

• Compare to 140CPS2xxx/4xxx: 52400 = 125V input; 2xxx=24V; 4xxx=48V。
