Mean Well PCD-16-1400B Power Supply 16W 1400mA

Yes, if the fixture needs 1400mA constant current and the LED load stays within the 8-12V constant current range. This B version accepts 180-295VAC input, which can matter where the available mains supply falls in that range. Output power is 16.8W.

It can be suitable when the LED module is a constant current 1400mA load and its total forward voltage is between 8V and 12V. Because it is a constant current driver, it is not a replacement for common constant voltage signage power supplies. The IP42 case also points to indoor or protected use.

Yes, that is the kind of load this model is built for, provided the array requires 1400mA constant current and operates within 8-12V. Its 16.8W rating keeps it in the small-array category rather than larger high-power systems. TRIAC dimming support may also help in compatible dimmed lighting setups.

Match the LED load to 1400mA constant current and confirm that the total forward voltage falls inside the 8-12V CC range. The number of LEDs depends on each LED's forward voltage, so the usable series length varies by LED type. If the module expects constant voltage, this driver is not compatible.

Yes, its rated operating range is -30°C to +60°C. That supports a wide range of indoor ambient conditions, but the IP42 enclosure still means it should be used in protected environments rather than directly exposed wet locations. Environmental fit depends on both temperature and ingress rating.
