The general module power supply has a minimum load limit, which varies from manufacturer to manufacturer and is generally around 10%. PQMII-T20 may experience current discontinuity due to the difficulty of the energy storage components in continuous current when the load is too light, resulting in unstable output voltage. This is determined by the working principle of the power supply itself. But what if the user does use it lightly or even without load? The most convenient and effective method is to add a certain false load, which is about 2% of the output power. It can be pre-set by the module manufacturer before leaving the factory, or the user can install an appropriate resistor outside the module as a negative load. It is worth noting that if the former is chosen, the module efficiency will be reduced. However, some circuit topologies do not have a minimum load limit, such as Dinglixin’s E-series module power supply, which can meet the normal use of users from no-load to full load.

When selecting a power supply for a multi-channel output module, attention should be paid to the power distribution between different outputs. Taking dual channel products as an example, PQMII-T20 generally has two types: one is a dual balanced load, that is, the dual current size is the same; Another type is unbalanced load, where the load currents of the main and auxiliary circuits are different, with the main circuit being larger and the auxiliary circuit being smaller. For this type of product, it is recommended to choose a power ratio of 1/5 to 1/2 between the auxiliary circuit and the main circuit. Only within this range can the voltage stability of the auxiliary circuit be guaranteed (within 5%), otherwise the voltage of the auxiliary circuit will be higher or lower. On the other hand, if the dual load is inherently different, it is advisable not to choose a balanced load module power supply, as this type of power supply is specifically designed for symmetrical loads. If the load is unbalanced, the accuracy of the auxiliary voltage is not high.
