    DALI-2 LED driver | constant current | 45 W | 500–1400 mA | 6–58 V DC | NFC | Push-Dim | PFC | IP20 | Sunricher SRP-2305N-45CC500-1400

    Sunricher SRP-2305N-45CC500-1400 is a single-channel constant current (CC) LED driver up to 45 W with DALI-2 (DT6) and Push-Dim control. The 500–1400 mA output current is set with an NFC app, so one model fits different LED modules, luminaires and spotlights.

    Key point:
    Instead of stocking several different drivers, you keep one: the required current is written via NFC before installation, with 0.1 mA resolution. The DALI-2 certified DT6 interface connects the driver to any DALI system, while in simpler projects a standard 230 V push button (Push-Dim) is enough.

    max. 45 W
    Output current
    500–1400 mA (NFC)
    Output voltage

    Control
    DALI-2 DT6 / Push-Dim

    Operating principle

    The driver is supplied with 200–240 V AC mains voltage and maintains a constant current in the LED load. The operating current is selected with the NFC app (iOS / Android) – the phone is held against the housing and the parameters are written: current, DALI address, group and scenes.

    Control is via the DALI-2 line (DT6 commands) or the Push-Dim input: a short press switches on or off, a long press changes brightness. Dimming uses the amplitude (CCR) method, range 0.01–100 %, with a selectable linear or logarithmic curve.

    Keep the power limit in mind: the maximum output voltage at the highest current is limited by 45 W. For example, at 1400 mA the load voltage must not exceed ~32 V, and the full 58 V can only be used up to ~775 mA.

    Why choose SRP-2305N-45CC500-1400?
    One compact driver covers the whole 500–1400 mA range, works with both DALI-2 and simple push-button control, and DALI addresses and groups can be assigned before installation – shortening commissioning on site.

    Main functions

    • NFC current setting 500–1400 mA – one model fits different LED modules, less stock to hold.
    • DALI-2 DT6 interface – compatible with universal DALI controllers supporting DT6 commands.
    • Push-Dim input – dimming with a standard 230 V push button without a DALI controller.
    • Deep dimming down to 0.01 % – smooth light level from minimum to full.
    • Selectable curve – linear or logarithmic – matched to human eye sensitivity.
    • Error reporting – the DALI system receives fault information – easier maintenance.
    • Automatic protections – the driver recovers by itself after short circuit, overcurrent or overheating.

    Where is it used?

    • LED luminaires in offices and administrative buildings
    • Accent lighting in shops, showrooms and display windows
    • Recessed LED downlights and spotlights
    • Linear LED luminaires with CC modules
    • Lighting scenes in hotels and restaurants
    • Meeting rooms and classrooms
    • Luminaires assembled by manufacturers with COB modules
    • DALI-2 lighting control systems in buildings

    Use by need

    For lighting designers.
    Precise current in 0.1 mA steps and DALI-2 DT6 allow luminous flux and scenes to be matched without compromise.
    For electricians / DALI integrators.
    Addresses, groups and scenes are written via NFC in advance – on site you only connect and test.
    For luminaire manufacturers.
    One driver for several luminaire models – simpler logistics and lower stock.

    Practical application

    If recessed luminaires with a 30 V / 1050 mA COB module are installed in an office, and part of the hall must be DALI-controlled while another part uses a simple push button, then each luminaire is set to 1050 mA via NFC (about 31.5 W), addresses and groups are assigned in the DALI zone, and in the corridor the Push-Dim input is connected to the existing push button. One driver model serves both zones.

    Pros

    • Current 500–1400 mA set via NFC, 0.1 mA step
    • DALI-2 DT6 and Push-Dim in one device
    • Dimming 0.01–100 %, linear / logarithmic curve
    • PF > 0.95, efficiency > 89 %, standby power < 0.5 W
    • Class II insulation – no earth wire required
    • Protections with automatic recovery
    • Compact – 145 × 45 × 28 mm

    Cons / limitations

    • 45 W limit: at 1400 mA the load voltage is no more than ~32 V
    • Setting the current requires a phone with NFC and the app
    • IP20 – indoor use only or inside a sealed luminaire housing
    • For constant current LED loads only – not suitable for 12/24 V LED strips (they need a constant voltage supply)
    • Operating temperature up to +45 °C – case cooling must be checked (Tc 85 °C)

    Safety and installation notes

    • Install and connect only with the power disconnected; work must be done by a qualified electrician.
    • Set the correct current via NFC before connecting the LED load – excessive current shortens LED module life.
    • Check that the load voltage fits 6–58 V and does not exceed 45 W at the selected current.
    • Do not connect the output in parallel with other drivers and do not short the output while powered.
    • Do not install in damp rooms without an additional sealed enclosure – IP20.
    • Ensure ventilation: the Tc point must not exceed 85 °C.

    Suitable when you need:
    • to power a constant current LED module or luminaire at 500–1400 mA
    • lighting control in a DALI-2 system or with a 230 V push button
    • one model for several luminaire types
    Check before use:
    • the LED module rated current and voltage (V × A ≤ 45 W)
    • whether your DALI controller supports DT6 commands
    • that you have a phone with NFC and the manufacturer app
    • the space in the luminaire or ceiling: 145 × 45 × 28 mm
    Important reminder: This is an LED driver, not a DALI controller or DALI bus power supply – a DALI system needs a separate controller and bus power supply; this driver is not suitable for 12/24 V LED strips.

    FAQ

    How is the output current set?
    With the manufacturer NFC app on a phone – current is written within 500–1400 mA in 0.1 mA steps.
    Can it be controlled without a DALI system?
    Yes – via the Push-Dim input with a standard 230 V momentary push button.
    What is the maximum voltage at 1400 mA?
    About 32 V, because total power is limited to 45 W.
    Is it suitable for 12 V / 24 V LED strips?
    No – strips need a constant voltage supply; this is a constant current driver.
    Is an earth wire required?
    No, the driver is Class II with a plastic housing.
    Is it compatible with other brands of DALI controllers?
    Yes, with universal DALI controllers supporting DT6 commands.
