PSW Series User Manual 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 Description 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.
GETTING STARTED 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. PSW 80V Series Operating Area 4.5 9.0 27 13.5 40.5 90 80 80 Type I Type II Type III 60 40 26.
PSW Series User Manual CC and CV Mode CC and CV mode Description When the power supply is operating in constant current mode (CC) a constant current will be supplied to the load. When in constant current mode the voltage output can vary, whilst the current remains constant. When the load resistance increases to the point where the current limit (ISET) can no longer be sustained the power supply switches to CV mode. The point where the power supply switches modes is the crossover point.
GETTING STARTED Conversely the power supply will operate in CC mode when the load resistance is less than the critical resistance. In CC mode the current output is equal to ISET and the voltage output is less than VSET.
PSW Series User Manual 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.
GETTING STARTED 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.
PSW Series User Manual 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 43. 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.
GETTING STARTED Pulsed or Peaked loads When the load has current peaks or is pulsed, it is possible for the maximum current to exceed the mean current value. The PSW power supply ammeter only indicates mean current values, which means for pulsed current loads, the actual current can exceed the indicated value. For pulsed loads, the current limit must be increased, or a power supply with a greater capacity must be chosen.
PSW Series User Manual Note The current output will decrease by the amount of current absorbed by the resistor. Ensure the resistor used can withstand the power capacity of the power supply/load. Reverse Current: Accumulative energy. CAUTION 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 WARNING 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 CAUTION 30 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. If using external voltage control, do not ground the external voltage terminal as this will create a short circuit.
