TS-15200 Output States

The TS-15200 has four output states. The output state can be read from software.

Constant Voltage

In constant voltage mode (or voltage-controlled mode), the module behaves like a voltage source and holds the voltage across the output terminals constant. In this mode the load current varies with load conditions. As long as the load current does not exceed the current limit setting, the module is in constant voltage mode and the output voltage is constant.

Constant Current

In constant current mode (or current-controlled mode), the module behaves like a current source and holds the current through the output terminals constant. In this mode the output voltage varies with load conditions. When the load tries to draw current from the module that exceeds the current limit setting, the module enters constant current mode and the output voltage drops below the programmed voltage.

Overvoltage

An overvoltage state can produce a saturated voltage measurement. The module enters an overvoltage state if the module voltage measurement is greater than the programmed voltage. This could be caused by an external fault detected on either Local+/- or Sense+/-. When an overvoltage state occurs, check the external wiring and DUT for any faulty conditions.

The module overvoltage error status can be read through software.

Note When reverse voltage is detected on the Local+ pin, module output is automatically disabled. To recover from this state, first ensure that the output no longer has reverse voltage and then re-enable the power output through software.

Output Disabled

The output enters a disabled state when it is explicitly disabled by the user or when fault conditions occur. Fault conditions include overtemperature errors, auxiliary power errors and reverse voltage errors.
