Unless specified otherwise, the specifications are for the following settings and conditions.
Loads are pure resistive loads. ●The product is warmed up for at least 30 minutes (with current flowing). ●After warm-up, the product must be calibrated correctly in a 23 °C ± 5 °C environment according to the appropriate calibration procedure. ●Values indicated by “TYP” are typical values. They are not guaranteed performance values. ●Values indicated by “rating” are ratings. ●Values indicated by “reading” are readings. ●Values indicated by “f.s.” are full scale values. ●The PWR-01 operates over a wide range of output voltage and output current within rated output power. However, the current that can be output with rated output voltage and the voltage that can be output with rated output current are limited by the rated output power. ●The current that can be output with rated output voltage and the voltage that can be output with rated output current are as follows. Maximum output current with rated output voltage = Rated output power/ rated output voltage. Maximum output voltage with rated output current = Rated output power/ rated output current. ●Rated load and no load are defined as follows:In constant-voltage mode (when the output current is set to a value greater than or equal to the maximum output current with rated output voltage) Rated load: Refers to a resistive load that, when the rated output voltage is applied,makes the flowing current 95 % to 100 % of the maximum output current with rated output voltage.No load:Refers to a load through which no output current flows. In other words,refers to an open load (no load being connected). In constant-current mode (when the output voltage is set to a value greater than or equal to the maximum output voltage with rated output current) Rated load:Refers to a resistive load that, when the rated output current flows, makes the voltage drop to 95 % to 100 % of the maximum output voltage with rated output current. Including the voltage drop in the load cables, the PWR-01 output voltage must not exceed the maximum output voltage with rated output current. No load:Refers to a resistive load that, when the rated output current flows, makes the voltage drop to 10 % of the maximum output voltage with rated output current or 1 V whichever is higher. ●The specifications of the PWR-01 apply to the rear-panel output terminals.
