| *1) The output voltage and current ranges can be set to 105% of the rated value, but the total output will be less. The extra capacity is used to compensate for external wiring loss and cannot be used as a regular value. |
| *2) Measured at room temperature of 23±5°C. |
| *3) Ripple and Noise (rms value) Measurement bandwidth up to 300 kHz |
| *4) Ripple and Noise (peak value) measurement bandwidth up to 20 MHz |
| *5) The time for the output voltage to reach ±1% of the setting value at 10% - 90% of rated voltage, and 10% and above of rated power, with a resistance load. (Fig. 1) |
| *6) Input voltage variation between 200~277VAC with a fixed loading 1~100%. |
| *7) CV Mode:
Constant line voltage; output current variation between 10% - 90% of the
rated value. CC Mode: Constant line voltage; output voltage variation between 10% - 90% of the rated value. CP Mode: Constant line voltage; output voltage*current variation between 10% - 90% of the rated value. |
| *8) All data were measured at the output terminal with local sensing, at 2% - 100% of rated voltage, 1% - 100% of rated current, after 30 minutes warm-up, in a room at 50°C and 80% RH. |
| *9) "Rise Time" means the time from 10% to 90% of rated voltage; "Fall Time" is the time to drop from 90% to 10% of rated voltage. |
| *10) The performance will be affected the character of the external wiring for multi-unit paralleling. |
| *11) LXI interface with minimum 3ms response time. The actual response time will be affected by your network's connection quality and LAN speed. |
