Frequently Asked Questions
What kind of LED applications is the Ltech DALI-25-150-900-E1A1 designed for?
This model is a 25W constant-current LED driver intended for internal lighting applications. Its selectable 150mA to 900mA output range makes it suitable for a variety of power LED fixtures that need current matching rather than a fixed-voltage supply.
Does this driver support DALI dimming only, or are other dimming options available?
The DALI-25-150-900-E1A1 supports DALI dimming and also lists Push DIM capability. It uses T-PWM digital dimming with a 0 to 100% dimming range, and the product description states LED startup at 0.01% is possible.
What makes this model different from a fixed-output LED driver?
A key difference is its selectable output current range of 150mA to 900mA, which gives more flexibility across compatible constant-current LED loads. That can simplify product selection when different fixtures in a project need different drive currents but still fit within this model's 25W and 58V limits.
What are the main electrical limits of this LED driver?
This model is rated at 25W maximum power and up to 58V output. It is a constant-current driver, with selectable rated current settings from 150mA through 900mA depending on the LED load requirements.
Is this driver suitable for low-level dimming and flicker-sensitive lighting projects?
Yes, this model is positioned for smooth low-end dimming, with LED startup at 0.01% noted in the product description. It also states 0 to 100% flicker-free dimming in line with IEEE 1789, which is relevant for applications where visual comfort matters.
How does this model handle demanding operating conditions and product longevity?
The specified operating temperature range is -30°C to 50°C, so it is built for a fairly wide indoor working environment. The driver also includes short-circuit, overload, overheat, and non-load protection, and it is backed by a 5-year warranty.
