The power supply has precise voltage adjustment with a trimmer potentiometer, but the output voltage is not stable in relation to the load. For example, without a load, the voltage is at 24 volts, with a load of 75 volts it drops to 22.8, and with a load of 150 volts it drops to 21 and something. It does not have voltage stabilization in the output. Additionally, the fan it has operates at speeds proportional to the current intensity we draw and makes a lot of noise with a consumption of at least 150 volts. Only time will tell if it can withstand long-term use
