FAQ

Can I use the PCD-25-1050A for higher-output LED downlights?

Yes, if the downlight is designed for 1050mA constant current and the total LED forward-voltage requirement stays within 16-24V. This driver provides up to 25.2W, so the downlight's LED load must stay within that rating.

Is the PCD-25-1050A suitable for constant-current signage modules?

It can be used for signage modules when the module assembly requires 1050mA constant current and operates within the 16-24V constant-current range. It is not a constant-voltage supply, so it should not be selected for constant-voltage LED signage products.

Can this model run a small LED array at 1050mA?

Yes, if the small LED array is specified for 1050mA constant current and its total forward voltage falls between 16V and 24V. The exact number of LEDs depends on each LED forward voltage, and the overall load must stay within 25.2W.

How do I verify LED compatibility with the PCD-25-1050A?

Match the load to 1050mA constant current and keep the combined LED forward voltage inside the 16-24V constant-current range. Because this is a constant-current driver, it is used differently from a constant-voltage power supply.

What operating conditions is the PCD-25-1050A rated for?

This driver is IP42 approved and has an operating temperature range of -30C to +60C (refer to the derating curve). Those specs make it appropriate for protected conditions rather than open wet-location exposure.

How does the PCD-25-1050A compare with nearby PCD models?

At 25.2W, the PCD-25-1050A/B cover 16-24V, the PCD-25-1400A/B cover 12-18V, and the PCD-25-700A/B cover 24-36V, while the PCD-25-350A/B are 20.3W with a 40-58V range. The A versions are for 90-135VAC input and the B versions for 180-295VAC input.
