Isolated DC-DC Converters

BOB3WH3 Series -- 3 Watt

Specifications subject to change without notice.

Test Configurations

All specifications are typical at nominal input, full load and 25°C unless otherwise stated.

◎DC Power Supply:

It 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

+(0.03% rdg + 4 digits).

◎Load: At full load.

◎Wires: The resistance of the wires must be small.

EX: Narrow input voltage range（±10%）
