GETTING STARTED Theory of Operation The theory of operation chapter describes the basic principles of operation, protection modes and important considerations that must be taken into account before use. Operating Area Description Background The PSW power supplies are regulated DC power supplies with a high voltage and current output. These operate in CC or CV mode within a wide operating range limited only by the output power.
PSW Series User Manual effective output is actually limited to the power limit of the unit. In this case the output current and voltage then depend purely on the load value. Below is a comparison of the operating areas of each power supply.

When in constant current mode the voltage output can vary, whilst the current remains constant.
PSW Series User Manual (VSET), the load resistance (RL) and the critical resistance (RC). The critical resistance is determined by VSET/ISET. The power supply will operate in CV mode when the load resistance is greater than the critical resistance. This means that the voltage output will be equal to the VSET voltage but the current will be less than ISET. If the load resistance is reduced to the point that the current output reaches the ISET level, the power supply switches to CC mode.
GETTING STARTED Slew Rate Theory The PSW has selectable slew rates for CC and CV mode. This gives the PSW power supply the ability to limit the current/voltage draw of the power supply. Slew rate settings are divided into High Speed Priority and Slew Rate Priority. High Speed Priority mode disables slew rate settings for CC or CV mode. Slew Rate Priority mode allows for user adjustable slew rates for CC or CV mode. The rising and falling slew rate can be set independently.
PSW Series User Manual may remain charged on the filter capacitors for some time and be potentially hazardous. In addition, bleed resistors also allow for smoother voltage regulation of the power supply as the bleed resistor acts as a minimum voltage load. The bleed resistance can be turned on or off using the configuration settings. Note By default the bleed resistance is on.
GETTING STARTED Alarms The PSW power supplies have a number of protection features. When one of the protection alarms are set, the ALM icon on the display will be lit. For details on how to set the protection modes, please see page 49. OVP Overvoltage protection (OVP) prevents a high voltage from damaging the load. OCP Overcurrent protection prevents high current from damaging the load. OTP Over temperature protection protects the instrument from overheating.
PSW Series User Manual Considerations The following situations should be taken into consideration when using the power supply. Inrush current Caution Pulsed or Peaked loads 28 When the power supply switch is first turned on, an inrush current is generated. Ensure there is enough power available for the power supply when first turned on, especially if a number of units are turned on at the same time. Allow at least 15 seconds between cycling the power.
GETTING STARTED Current limit level Measured Ammeter current Reverse Current: Regenerative load When the power supply is connected to a regenerative load such as a transformer or inverter, reverse current will feed back to the power supply. The PSW power supply cannot absorb reverse current. For loads that create reverse current, connect a resistor in parallel to the power supply to bypass the reverse current. This description only applies when the bleed resistance is off.
PSW Series User Manual Reverse Current: Accumulative energy. When the power supply is connected to a load such as a battery, reverse current may flow back to the power supply. To prevent damage to the power supply, use a reverse-currentprotection diode in series between the power supply and load.
GETTING STARTED Grounding The output terminals of the PSW power supplies are isolated with respect to the protective grounding terminal. The insulation capacity of the load, the load cables and other connected devices must be taken into consideration when connected to the protective ground or when floating. Floating As the output terminals are floating, the load and all load cables must have an insulation capacity that is greater than the isolation voltage of the power supply.
PSW Series User Manual Grounded output terminal If the positive or negative terminal is connected to the protective ground terminal, the insulation capacity needed for the load and load cables is greatly reduced. The insulation capacity only needs to be greater than the maximum output voltage of the power supply with respect to ground.
