Modes of Operation of the Meanwell HLG Transformers:
The well-known and established Meanwell HLG power adapters can be set up with a variety of different options, like the dim function for example. These are described below.
Indicator for that is always the last character in the product description. (Indicator “Z” in the following example: HLG-xxxH-yyZ)
The type without a last character in the voltage information is an exception. (yy) This Meanwell power adapter does not offer any adjustments, but provides protections according to IP67.
Typ A (e.g. HLG-240-12A):
Type A enables alternative constant current or constant voltage operation. This is dependent on the load and settings via internal potentiometers which are hidden behind small rubber covers for protection against moisture of the Meanwell HLG.
- Constant voltage operation:
Via the Vo.ADJ. controller the output voltage can be set according to data sheet specifications in a range around the nominal secondary voltage (data sheet specifications: Voltage Adj. Range): This voltage is held as long as the maximum power is not exceeded. Then the power adapter switches in the constant current mode.
- Constant current mode and works as constant voltage source: The regulator Io.ADJ serves to adjust the maximum operating voltage. The Meanwell HLG goes into current limit and functions as constant current source. This however only works if the associated load is enough low-ohmic to the operation voltage. (Ohm’s law), like it’s the case with LEDs.
Typ B (e.g. HLG-185-12B)
Type B was specifically designed for dim operation of LEDs or LED modules/LED lamps. The specialty are its different options for dimming.
Besides the connection lines for the line input voltage (tripolar, green-yellow, brown, blue) and the output line (red, black) the Meanwell HLG Type B also has a third connection line with the colors (blue, white). This input enables the dim function as it is described in the following.
- PWM (Pulse width modulation):
A 10Vcontrol signal is plugged to the input, which has a ratio of the impulse width that conducts the output voltage of the power adapter and therefore the brightness of the plugged LED lamps. (Caution. The LED lamp has to be suitable for dim operation). For the provision of the PWM signal there are different products on the market that create for example a PWM signal out of phase stage dimming. This way different operation devices are often operated parallel. The adapter DAP-04 of Meanwell that works as a DALI-PWM adapter and can control even the efficient Meanwell transformers over DALI, is especially popular. The PWM ratio determines the output voltage as the following table shows: Usual PWM frequencies between 100Hz and 3kHz.
- 1-10V signal:
If a variable voltage of an external source between 1 to 10V is applied to the input, the output voltage changes according to the following table:
Important: Potential isolation between the output voltage and the control voltage.
- Potentiometer regulation:
If a potentiometer adjustable resistor between 0 and 100K ohm is plugged, the output voltage can be assigned to the set resistance value as follows.
If different devices are operated at the same time, lower resistance values have to be chosen accordingly.
Typ C (e.g. HLG-320-24C)
The only difference between Type C and Type A is just the way of connection. Instead of wires Type C has a terminal block.
