The Thurlby Thandar TTI PLP power supply series is a simple programmable bench power supply.
Items that can be set include :
- Output voltage.
- Output current.
- Output On/Off.
- Voltage limit.
- Current limit.
The device operates in two modes; Constant Current (CI) or Constant Voltage (CV). By default, and on reset, the device is in CV mode. In CV mode the current set point acts as a current limit whilst the current output is 0. CI mode is activated when the load resistance and voltage combination would mean that a current would flow above the current set point. In CI mode, the voltage set point acts as a voltage limit and the voltage output is dynamically calculated. In this mode, there is an active current output.
The IOC has macros for the voltage limits (MAX_VOLT, MIN_VOLT) and current limits (MAX_CURR, MIN_CURR). These can be changed so that in the event of a different model of PSU, alternative limits are supported. The TTI355 supports I = 0.01, 5.0 and V = 0.0, 35.0.
The device has an error state which indicates when the device has received a command value outside the instruments limits.
