How To Choose A Suitable Power Supply

  • Decide a suitable wattage level, including safety margin.
  • Verify your design of LED driving circuit: direct drive by PSU [choose a constant current (C.C.) mode LED power supply] or add additional driving IC to get a more precise constant current level [choose LDD, LDH or LDB].
  • Verify whether the application need PFC function.
  • Verify location of assembly and the required level against dust and humidity for the LED power supply (enclosure style, IP level, dry/damp/wet location).
  • Verify the required safety certificates.
  • Need to adjust the output voltage and/or output current or need the dimming function?

Suggested System Design

Setting Circuit Diagram Description Advantage &
Disadvantage
Use constant current (C.C.) mode power supply only circuit diagram
Using MEAN WELL's C.V. + C.C. mode or C.C. mode LED power supply as constant current source and feed the LED arrays directly.
MEAN WELL product:
APC / LPC / ELN / PLN / PLC / LPF
/ NPF / OWA / HLN / GSC / PLD /
PLM / CLG / CEN / HLG / HLG-C /
HSG / HVG / HVGC / HBG / PLP /
HLP / LCM families
Advantage
  • Simplest design, no need LED driver IC
  • Lower price
  • Higher efficiency with the best lumen per watt(lm/w)
Disadvantage
  • Unbalanced driving current and shorter LED life time
  • LED chips should be sorted for similar VF
Use constant voltage (C.V.) mode power supply with DC-DC LED driver circuit diagram
Using AC/DC C.V. mode LED power supply and separate DC/DC LED drivers.
MEAN WELL product:
Any AC/DC LED power supply +
LDD, LDH or LDB series
(DC/DC LED driver)
Advantage
  • Independent output channels, the most balanced current for paralleled LED strips
  • No need to sort the VF of LED
  • Longer LED lifetime
  • Failures in any string do not affect the other string
Disadvantage
  • Higher price
  • Complicated circuit design
  • Lower system efficiency
  • Larger in power supply volume

Note 1
At the moment of power on, the LED power supply will work in C.V. mode and can provide a peak output current; after the LED turns on, the LED power supply will go into C.C. mode.

Note 2
The C.C. only LED power supplies are suitable for directly driving LED modules, but not suitable for connecting with additional DC-DC LED drivers.

Note 1
C.V. represents Constant Voltage Mode Output, whereas C.C. represents Constant Current Mode Output. For C.V.+C.C., C.C., and C.V. operations, please refer to Application Q&A section on MEAN WELL LED website. (The C.C. only LED power supplies are suitable for directly driving LED modules, but not suitable for connecting with additional DC-DC LED drivers.)
Note 2
  • Single-Stage PFC : No hold-up time and higher Ripple & Noise. Not recommended to use in regions with unstable utility.
  • Two-Stage PFC : Longer hold-up time and lower Ripple & Noise. Suitable for LED lighting and general industrial applications.
  • Non-PFC : PF<0.6 and target at regions where PF compliance is not required.
Note 3
3-in-1 dimming: 1~10Vdc, PWM signal, or resistance. Timer: Timer dimming function, please contact MEAN WELL for details.
Note 4
