Frequently Asked Questions - LPHC-18-350 Mean Well
What is the LPHC-18-350 used for?
The LPHC-18-350 is a constant current LED driver designed to power high-power LEDs or LED modules that require 350 mA drive current, with a total power up to 18 W. It is suitable for indoor lighting applications such as downlights, track lights, or panel lights.
How do I wire the LPHC-18-350?
Connect the AC input (100-240V) to the L (line) and N (neutral) terminals. Connect the LED load to the +V (positive) and -V (negative) terminals. Ensure polarity is correct. For dimming, use the DIM+ and DIM- terminals with a 0-10V source, PWM signal, or DALI bus depending on the selected mode. Refer to the manual for wiring diagrams.
What dimming methods are supported?
The LPHC-18-350 supports 0-10V analog dimming, PWM dimming, and DALI digital dimming. The dimming mode is selectable via a switch or jumper on the unit. The dimming range is typically 10-100% output current.
Can I use this driver for outdoor lighting?
No, the LPHC-18-350 has an IP20 rating, which means it is not protected against moisture or dust. It is intended for indoor, dry locations only. For outdoor use, you would need a driver with a higher IP rating (e.g., IP67).
What is the maximum LED voltage?
The output voltage range of the LPHC-18-350 is 27-54 VDC. This means the forward voltage of your LED string must be within that range. For example, it can drive a single LED with ~3V or a series of up to 18 LEDs (assuming 3V per LED).
How do I select the dimming mode?
Locate the DIP switch or jumper on the driver. Typically, positions are labeled for 0-10V, PWM, or DALI. Set the switch according to your control method. Refer to the manual for exact switch positions. Note that the unit must be disconnected from power before changing the setting.
What happens if the load is shorted or disconnected?
The driver includes short circuit, overload, and overvoltage protections. If the output is shorted, the driver will shut down or reduce output to prevent damage. A disconnected load will cause the output voltage to rise to the maximum (54V) but the driver will not be harmed. Once the fault is removed, the driver resumes normal operation.
Is the LPHC-18-350 compatible with smart home systems?
Yes, through its DALI or 0-10V interface, it can be integrated with building automation systems. For 0-10V, you can use a compatible dimmer or controller. For DALI, you need a DALI master controller. The driver does not have built-in wireless connectivity.
What is the expected lifespan of this driver?
Mean Well drivers are designed for long life, typically 50,000 to 100,000 hours at rated load and temperature. The actual lifespan depends on operating conditions such as temperature and load. Using the driver within its specified temperature range will maximize lifespan.
Where can I download the user manual?
