The PS12V4000 delivers a rock-solid 12-volt rail for embedded controls, LED arrays and telecom subsystems. A high-frequency LLC topology, synchronous rectification and low-ESR polymer caps yield < 50 mVpp ripple while maintaining ≥ 88 % efficiency from any global mains input. Factory-tinned 18 AWG leads drop straight into screw terminals or PCB solder pads—no barrel jacks, no crimp time.
Key Technical Advantages
- Precision Regulation ±1 %/±2 % (line/load) via opto-isolated secondary feedback.
- Class B EMC Headroom — CISPR 32 with 6 dB margin; no extra ferrites.
- 4 kV EFT / 2 kV Surge Immunity per IEC 61000-4-4/5 without external MOVs.
- All-Round Protection: OCP, OVP, OTP, hiccup-mode SCP (auto-recover < 200 ms).
- MTBF > 250 000 h (MIL-HDBK-217F, 25 °C, GB)—105 °C polymer caps & SiC diodes.
- Wide Thermals: –20 °C … +70 °C; derate 2 % / °C beyond 50 °C.
- Pre-Tinned Leads: 18 AWG OFHC Cu, 150 mm, SAC305 tinning (IPC J-STD-002B).
