2. Input power :

Pin = Vin x Iin

Vin：Input voltage

Iin：Input current

3. Output power :

Pout = Vout x Iout

Vout：Output voltage

Iout：Output current

4. Efficiency :

Pout: Output power

Pin: Input power

5. Voltage accuracy:

Vout：Output voltage

Vout(nominal)：Nominal output voltage

6. Line regulation: (1) Wide input voltage range and regulated output voltage series.

(2) Narrow input voltage range（±10%）and unregulated output voltage series.

Vout(+10%)：Output voltage at Vin = 1.1xVin(nominal)&full load

Vout(-10%)：Output voltage at Vin = 0.9xVin(nominal)&full load

Vout：Output voltage at Vin = Vin(nominal)&full load
