| Remarks |
Ripple and noise measurements are made by the leaning method: using a 12" twisted pair cable with 0.1uF and 47uF capacitors connected in parallel at the terminals and peak-to-peak measurements are made at a bandwidth of 20MHz. The efficiency is tested at an input voltage of 230VAC, rated load, and 25°C ambient temperature. Accuracy: Includes setting error, linear adjustability and load adjustability. Linear Adjustment Rate test method: from low voltage to high voltage at rated load. Load Adjustment Rate test method: from 0% to 100% of rated load. Start-up time is measured at cold start. Fast and frequent switching on and off may increase the start-up time. When the operating altitude is higher than 2000 meters, the operating ambient temperature should be adjusted down by 5°C/1000 meters. |
