The extensive data sheets of Mean Well LED drivers can easily unsettle inexperienced users. Which possibilities are available, LED modules to be wired with drivers<\/a> we've already treated. In this article we will show which criteria are especially important when we configure LED system.<\/p>\n

Constant Voltage, Constant Current, Constant Power<\/h2>\n

The functional principle of an LED driver is based on one of three parameters: voltage, current or power. Therefore, the Mean Well portfolio also differentiates between Constant voltage<\/strong> LED power supplies (CV)<\/strong>, Constant current<\/strong> LED Drivers (CC)<\/strong> and Constant power<\/strong> (CP)<\/strong> variants.<\/p>\n

Mean Well Driver Series ELG, HLG, XLG and LCM<\/h3>\n

The Mean Well ELG and HLG series offer mainly CV and CC models, while the XLG series consists of CP and CV power supplies. The Mean Well LCM series is a special type of power supply for low constant current applications. With this type, the constant current can be adjusted in steps.<\/p>\n

There are numerous other series of Mean Well, which are mostly designed for very special applications. Therefore, in this overview we will concentrate on these four LED driver series, which are used particularly frequently in the horticulture sector<\/p>\n

Mean Well ELG-240 data sheet <\/h2>\n

As an example we look at the Data sheet of the ELG-240<\/a> on.<\/p>\n

This model exemplifies the variants with constant voltage and constant current (CV+CC).<\/p>\n

The ELG series are high-quality LED power supplies with up to 240 W. The manufacturer promises more than 50.000 hours lifetime under normal conditions and offers a 5 years warranty.<\/p>\n

Model variant - manufacturer part number<\/h3>\n

To differentiate between different variants, Mean Well divides the part number into series, specified output power, voltage and a suffix for the available control and dimming options.<\/p>\n

Dimmable mean well drivers<\/h3>\n

We are primarily interested in the normal, dimmable variants A, B and AB. Thanks to the 3-in-1 dimming function, various dimmers and control units can be connected to the corresponding connections of the B and AB variants. E.g. a resistance dimmer (potentiometer) or also the analogue outputs of CresControl<\/a>.<\/p>\n

With the A-version the current can only be adjusted from 50-100% by operating the potentiometer built into the housing with a screwdriver.<\/p>\n

CV and CC - mixed mode<\/h3>\n

As with the HLG series, the standard version of the ELG driver also has a CV and CC \"mixed mode\". This means that the driver can be controlled via<\/p>\n
