We are doing the op amp simulation experiments or experiments, there must be a positive and negative power supply, but will encounter some situations:

The first is that we need to use the AC adapter into a positive and negative power supply, this is a relatively bulky and must have 220V AC.

The second is to use a DC / DC converter into a positive and negative power supply module finished, but noise, low power, the price is more expensive, require a relatively high input voltage.

Therefore, in these cases we have made a portable, high-current, low-noise power supply experiment.

Features:

1. Multiple output voltage: 3V, ± 5V, ± 12V, ± 15V.

2. Large current: 3V, 300mA
± 5V, 200mA
± 12V, 120mA
± 15V, 100mA

3. The three kinds of external power connector.
USB powered, direct interface to take power from the computer USB.
DC power supply connectors and terminals, you can easily access our common adjustable power or lithium battery.

4. Very wide supply voltage: 2V-16V DC. Be careful not to exceed 16V, or it may be permanently damaged!

5. Low noise: an internal linear regulator noise under full load conditions only 5mVp-p.

6. Size: 100x50x19mm(L*W*H)
