WSZ796 & WSZ895 Model
The WSZ796 and WSZ895 power supplies have outputs which can be adjusted from 5V to 30Vdc. The WSZ895 also has an auxillary 12V, 1A rated output. The main output produces 50W of continuous power from 20V to 30V. At 5V the output is rated at 3.3A load or 17W. Between 5V and 20V the output power is linearly interpolated as shown in Diagram 1 below.
Additionally, there is a short term intermittant loading capability at up to 1.5X the nominal continuous output power rating. For loads with signifigant loading times in the 5 to 15 minutes area, an explanation of output loading characteristics during surge loading is available at the following link:

Output Power Vs DC Output Voltage
The adjustability feature can be supplied in 2 basic styles. It can either be a mechanical adjustment accessible from the bottom surface of the power supply or it can be an analog programming signal accessible from the end of the cord.
The analog programming signal may be either a variable voltage or a variable resistance. When the signal is variable voltage, the level must be between 1 to 5Vdc. One volt at the control input will set the output to the maximum level (30V), 5 volts at the control input will set the output to the lowest level (5V).
A variable resistance at the control input between 1K to 10K can alternately be used to set the output voltage. Contact the factory engineering department for specific information regarding this option.
