Frequently Asked Questions
What is the main application for the Ltech SE-20-250-1000-W2B3?
This model is intended for color temperature lighting applications that use a constant current LED load. It combines 20W output with dimming-oriented control features, including soft-on and fade-in behavior for smoother visual transitions. The product description also highlights Bluetooth Mesh and Tuya protocol support for app-based lighting control.
Is the SE-20-250-1000-W2B3 a constant current or constant voltage power supply?
It is a constant current power supply, not a constant voltage model. The rated output current is 250 mA, and the listed output voltage is 59 V. That makes it suitable for LED products designed around a 250 mA constant current driver requirement.
What are the key electrical specifications of this model?
The SE-20-250-1000-W2B3 is rated at 20W with a rated current of 250 mA. Its listed output voltage is 59 V, and the dimming control type is PWM. These specifications make it a low-power constant current option for compatible LED lighting applications.
Does this power supply support smart control platforms?
Yes. The product description states that it supports Bluetooth Mesh and the Tuya application protocol. It also supports control from iOS and Android devices through Bluetooth connection.
What operating temperature range is specified for this power supply?
The specified ambient temperature range is -20°C to 50°C. That gives it a usable range for many indoor and protected commercial lighting environments. Buyers should match the installation environment to this stated temperature window.
What distinguishes this model for buyer evaluation on a product page?
This model combines constant current output with smart lighting control features rather than serving as a basic non-connected driver. The description specifically calls out Bluetooth Mesh, Tuya support, iOS/Android control, soft-on and fade-in dimming, and T-PWM flicker-free performance. It also carries a 5-year warranty and uses a V0 flame-resistant polycarbonate housing.
