2x (30V 5A) 3-channel Bench Power Supply Yihua 3005D-II + 2.5V / 3.3V / 5V 3A
Bench power supply Yihua 3005D-II DC
The series of Yihua triple (three-channel) power supplies for currents up to 5A are reliable and precise laboratory equipment with regulated and stabilized DC voltage and regulated (limited) current consumption. The output voltage and current are regulated by the knobs. Coarse and fine for voltage and coarse for current. The power supplies are protected against the effects of short circuits and thus against overload and damage. Cooling is provided by the built-in fan. They are equipped with 2 readable LED displays. The power supplies can be used in the design of electronics products, scientific works, in laboratories, on production lines and in teaching.

Characteristics:
The Yihua 3005D-II laboratory power supply has two adjustable DC voltage channels. Large backlit LED display and voltage and current adjustment knobs installed in a way that eliminates the risk of accidental change of settings. The first and second channels are independent and can be set to separate current and voltage limits.
The third voltage output gives one of the three defined voltages: 2.5V, 3.3V and 5V with a maximum current of 3A
This power supply can operate in three operating modes:
Independent, where each channel is controlled separately, allowing you to set the voltage in the range of 0-30V and the current up to 5A
For parallel operation, the maximum output voltage is 30V and the current is 10A
The serial maximum output voltage is 60V and the current is 5A
The laboratory power supply has three outputs that can be separately set and activated simultaneously
The large and backlit 4-digit LED display shows the set voltage and the consumed current. And the current power consumption in Watts.
The whole thing is enclosed in a solid metal housing with a large heat sink in conjunction with a thermal switch that starts the fan only after exceeding 45 degrees C, and not, as in some cheap models, immediately after turning on the power supply, it allows you to enjoy stable and quiet operation.
