MEAN WELL IDLC-25-350 25W Constant Current Mode LED Driver

Product Information

The IDLC-25 series is a 25W Constant Current Mode LED Driver. It is designed to provide a constant current output to power LED lighting fixtures. The driver operates within a voltage range of 90-295VAC and a frequency range of 47-63Hz. It has a high power factor, with PF>0.95 at 115VAC, PF>0.92 at 230VAC, and PF>0.9 at 277VAC at full load.

The IDLC-25 series offers three different models:

• IDLC-25-350: Rated current of 350mA and rated power of 24.5W. The constant current region is 49-70V, and the output open circuit voltage is maximum 100V.
• IDLC-25-500: Rated current of 500mA and rated power of 25W. The constant current region is 35-50V, and the output open circuit voltage is maximum 75V.
• IDLC-25-700: Rated current of 700mA and rated power of 25.2W. The constant current region is 25.2-36V, and the output open circuit voltage is maximum 63V.

The IDLC-25 series also includes an IDLC-25-1050 model with a rated current of 1050mA, rated power of 25.2W, constant current region of 16.8-24V, and maximum output open circuit voltage of 36V. The driver has a setup time of 500ms/230VAC or 1200ms/115VAC. It provides an auxiliary DC output of nominal 12V at 50mA (for A-Type only). The total harmonic distortion is less than 20% at load conditions of 70%/115VAC, 230VAC or 75%/277VAC. The efficiency of the driver is approximately 82%.

Product Usage Instructions

1. Ensure that the input voltage is within the range of 90-295VAC and the frequency is within the range of 47-63Hz.
2. Connect the LED lighting fixture to the driver’s output terminals, matching the required constant current and voltage specifications.
3. If applicable, connect any auxiliary devices that require a nominal 12V DC output to the A-Type auxiliary output terminals.
4. Check the total load connected to the circuit breaker. The IDLC-25 driver can support a maximum of 32 units (circuit breaker of type B) or 32 units (circuit breaker of type C) at 230VAC.
5. Ensure proper grounding of the driver and all connected devices to prevent leakage current.
6. To start the driver, apply power by connecting it to a suitable power source. The driver has a cold start inrush current of 0.4A/115VAC, 0.16A/230VAC, and 0.13A/277VAC.

DRIVING METHODS OF LED MODULE

• This series works in constant current mode to directly drive the LEDs.

In the constant current region, the highest voltage at the output of the driver depends on the configuration of the end systems. Should there be any compatibility issues, please contact MEAN WELL.

Typical output current normalized by rated current (%)

DIMMING OPERATION

2 in 1 dimming function

• Output constant current level can be adjusted by applying one of the two methodologies between DIM+ and DIM-: 0 ~ 10VDC, or 10V PWM signal.
• Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers.

Applying additive 0 ~ 10VDC

Applying additive 10V PWM signal (frequency range 300Hz ~ 3KHz):

Note:

1. Min. dimming level is about 8% and the output current is not defined when 0%< Iout<8%.
2. The output current could drop down to 0% when dimming input is about 0Vdc or 10V PWM signal with 0% duty cycle.
