LED power supply | Mean Well LPHC-18-350

LED power supply - choose the right one for Your project.

LED power supply parameters 350mA DC and 18W headroom for demanding loads. The sealed body protects electronics from dust and moisture. This model comes from the trusted Mean line. Typical uses include indoor LED strips, display cases and furniture lighting, and low-voltage electronics. It brings stable output, low ripple, and premium build quality.

Protections built into the led power supply

• Over-voltage protection (OVP) shields LEDs from spikes.
• Over-current protection (OCP) prevents overload damage.
• Short-circuit protection (SCP) auto-recovers after faults.
• Over-temperature protection (OTP) limits heat-related failures.
• EMI filtering and, where applicable, active PFC for cleaner power.

When to use power injection

Projects using LED tape at 12 V or 24 V can suffer voltage drop on long runs. Brightness fades and colors shift. Feed 12 V or 24 V at multiple points to keep light uniform. For constant-current modules like this unit, power injection is not used; instead, wire series chains within the rated voltage window. Combine this method with a 350ma 18w power supply to stabilize each section.

Sizing your power source

Sum the LED load and add a 20–30% margin. This protects lifespan and thermal performance. Match polarity, check ambient temperature, and allow airflow. For sealed installs, derate output. Use the mean well lphc-18-350 psu only where it adds value, and pick certified units for safety.

FAQ — Your questions answered

Q: Can I run several strips in parallel?
A: Yes, if total current stays within the limit and each branch is fused.

Q: Why does my strip dim at the end?
A: Voltage drop. Add power injection and use thicker supply cables.

Choose cables with low resistance, avoid sharp bends, and double-check polarity before power-up. Test sections incrementally to catch wiring errors early.
