TEST CONFIGURATIONS

All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.

We reserve the right to change specifications based on technological advances.

DC Power Supply: offers a wide voltage and current range precisely.

Current Meter (A): Accuracy

 200µA~200mA 4 ranges ±(0.2% rdg + 2 digits)

2000mA~20A 2 ranges ±(0.3% rdg + 2 digits)

Voltage Meter (V): Accuracy

 ±(0.3% rdg + 4 digits)

Load: At Full Load

Wires: The resistance of the wires must be small.

1. Input Voltage Range: Narrow input voltage range (±10%); Wide input voltage range (2:1 and 4:1)

Ex: Narrow input voltage range (±10%)

5VDC nominal input

 4.5~5.5VDC

12VDC nominal input

 10.8~13.2VDC

24VDC nominal input

 21.6~26.4VDC

Wide input voltage range 2:1

5VDC nominal input

12VDC nominal input

24VDC nominal input

48VDC nominal input

Wide input voltage range 4:1 (W)

24VDC nominal input

48VDC nominal input

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:

Efficiency= Pout

Pin

x100%

Pout: Output Power

Pin: Input Power

5. Voltage Accuracy:

Vout: Output Voltage

Vout

Vout (nominal): Nominal output voltage

6. Line Regulation:

(1) Wide input voltage range and regulated output voltage series

Vout(LL)

HL: High Line Input Voltage

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