FAQ

Can the PCD-16-350B power a 350mA LED downlight from 180-295VAC mains?

Yes, if the fixture requires 350mA constant current and its LED load stays within the 24-48V constant current range. This B version is for 180-295VAC input, which is the key input-side difference to watch. Its output power is 16.8W.

Is this model suitable for small LED arrays with a longer series voltage requirement?

Yes, that is where this driver is usually a better fit than lower-voltage constant current models, as long as the array needs 350mA and falls within 24-48V. The higher CC voltage range supports longer series LED arrangements than 8-12V or 12-16V drivers. It remains a constant current driver, not a constant voltage unit.

Can I use the PCD-16-350B for indoor illuminated signage with constant current LED modules?

It can be used for indoor signage applications when the LED modules are designed for 350mA constant current and the full load voltage is within 24-48V. Its IP42 housing makes protected indoor placement more appropriate than exposed outdoor use. TRIAC dimming may also be relevant for compatible dimmed signage or display lighting.

How do I size the LED load for this driver?

Match the load to 350mA constant current and make sure the total LED forward voltage is within the 24-48V CC range. The number of LEDs depends on the forward voltage of each LED, so the acceptable series length changes by LED type. If the load is designed for constant voltage, this is not the right driver.

What kind of environment is the PCD-16-350B intended for?

This model is intended for protected environments, with an IP42 case and an operating temperature range of -30°C to +60°C. That supports a wide range of indoor ambient temperatures, but not direct wet exposure. Environmental suitability depends on both the ingress rating and the ambient conditions.
