1. All the parameters in has not specified, all is in 230VAC voltage input, rated load and 25¡æ conditions measuring income value.
2. Ripple and noise voltage is in 20MHz bandwidth with 12 inches oscilloscope twisted pair end and 0.1¦Ìand 47¦Ì capacitance measurement when.
3. Tolerance is voltage setting error, the voltage adjustment rate and the current adjust rate combined. |
