Frequently Asked Questions

Can I use the LCM-40 for higher-power LED downlights?

Yes, the LCM-40 is a constant current LED driver rated at 42W with a 700mA default output. Its 2-57V CC range gives it more headroom than the 25W versions for LED downlights that need a higher-power constant current driver.

Is the LCM-40 suitable for larger signage LED modules?

It can be suitable when the signage modules are built for constant current operation rather than constant voltage. This model delivers 700mA across a 2-57V CC range and is rated at 42W, which supports larger constant current loads than a 25W driver.

Can the LCM-40 power a small or mid-size LED array?

Yes, the LCM-40 is designed for constant current LED loads and is rated at 42W. With a 2-57V output range at 700mA default, it can cover a broader range of constant current LED arrays than lower-power drivers in the series.

How do I check compatibility for the LCM-40?

Confirm that your LEDs require a constant current driver and that their total forward voltage stays within the 2-57V CC output range. The number of LEDs depends on the forward voltage of each LED, so compatibility should be based on forward-voltage total rather than a fixed LED count or constant voltage assumption.

How does the LCM-40 compare with other LCM family models?

The 25W group includes LCM-25, LCM-25BLE, LCM-25DA, and LCM-25KN at 25.2W with 700A and 6-36V, plus LCM-25DA2 at 25W with 0.7mA and 277-180V. In the 40W class, LCM-40, LCM-40BLE, LCM-40DA, and LCM-40KN are listed at 42W with 700A and 2-57V, while LCM-40DA2 is 40W with 0.6mA and 295-180V, LCM-40TW is 40W with 0.7mA and 20-50V, and LCM-40U is 35W with 700A and 2-50V; above that, LCM-60, LCM-60BLE, LCM-60DA, and LCM-60KN are 60.3W with 700A and 2-86V, LCM-60DA2 is 6W with 0.9mA and 295-180V, and LCM-60U is 50.4W with 700A and 2-72V.
