Open PDF file（108 Kb)
Unless specified otherwise, the specifications are for the following settings and conditions.
- The load is a pure resistance.
- The warm-up time is 30 minutes (with current flowing).
- After warm-up is complete, the PAT-TM/TMX series must be calibrated correctly according to the procedures given in the operation manual in a 23 °C ± 5 °C environment.
- TYP (typical) values do not guarantee the performance.
- rtg: Indicates the rated output.
- rdng: Indicates the reading.
- Rated load and no load are defined as follows.
During constant voltage operation (set the output current at the rated voltage output greater than equal to the rated output current)- Rated load: Refers to a load with a resistance that makes the current that flows when the rated output voltage is applied to be 95 % to 100 % of the rated output current at the rated output voltage.
- No load: Refers to a load through which no output current flows or an open output terminal condition with no load connected.
During constant current operation (set the output voltage at the rated output current greater than equal to the rated output voltage)- Rated load: Refers to a load with a resistance that makes the voltage drop when the rated output current is supplied to be 95 % to 100 % of the maximum output voltage at the rated output current.
The output voltage of the PAT-TM/TMX series including the voltage drop in the load cable must not exceed the maximum output voltage at the rated output current. - No load: Refers to a load with a resistance that makes the voltage drop when the rated output current is supplied to be 10 % of the maximum output voltage or 1 V, whichever is greater, at the rated output current.

*1. The maximum preset voltage and current are used to determine constant voltage or constant current operation when the activation point of the constant voltage or constant current operation is set to the rated output voltage or current. It does not guarantee power supply to the load exceeding the rated output voltage or current.
To establish a constant voltage operation at the activation point (rated output voltage or current), set the output current (I Set) so that rated output current < I Set ≤ maximum preset current. Likewise, to establish constant current operation, set the output voltage (V Set) so that rate output voltage < V Set ≤ maximum preset voltage.

*4. The time it takes for the output voltage to fall from 90 % to 10 % of the rating when the output is turned off.
